Hexcast comprises two distinct components. The plugin (VST3, Audio Units, or AAX) runs as an insert effect within your DAW and the Hexcast Web Client, the microsite web application that runs on the device required to monitor your master bus through.

Hexcast can support up to six simultaneous connected devices with varying sample rates and channel configurations. Each client can divert the audio from your main studio monitors to its own internal loudspeaker, enabling the monitoring of your mix in real-time to achieve a balanced mix across the devices.

In addition to managing multiple connections, Hexcast intelligently retrieves the client audio configuration. Such as sample rate and channel configuration. It uses this information to resample the stream on the fly to ensure the data is in the correct format for the client. For example, suppose your phone is configured to support a 48kHz sample rate and your DAW is set to 44.1 kHz, Hexcast will resample the stream in real-time to match your phone to ensure accurate playback.

As Hexcast has been designed for In The Box (ITB) usage it should be instantiated as the last plugin on your master bus. The reasoning for this is that it routes the audio through your studio monitors when a client device is not streaming and diverts the audio from your studio monitors when a client device stream is active.

The plugin supports both mono and stereo configurations only. Although most audio applications are stereo based. In the event that the client’s device only supports mono configuration, Hexcast will convert the audio to mono to conserve bandwidth.

When you launch the plugin, you will see your local IP address in the LCD address bar on the main panel along with the default port for the Hexcast internal web server. This indicates that the plugin is ready to serve audio via its own internal web application. (More on that later.)

In the event that the plugin cannot connect to your network, you will be presented with the IP resolution. This indicates that the plugin is currently searching for network connectivity, and until the IP address is determined will render the plugin non-operational.

As you can see the main interface is quite simple. The UI is mostly presentational with options to manage the plugin configuration. As a web client device joins the session, a hexagon icon is displayed, gently rotating in a carousel in Mex’s hand.

Furthermore, the icon depicts the type of device connected to Hexcast, allowing you to differentiate between devices. Click the device icon to reveal further details about the connected devices. Such as sample rate, device type and the I.D. Clicking anywhere on the main panel will return the icon back to the rotating carousel.

The web client application serves as the controller for the client device UI run in a browser. The interface adopts a simple design that is both clean and accessible. Keyboard accessibility is important to allow the use of a remote control when accessed on a TV or device without a mouse or touchscreen.

Hexcast offers two connection protocols, HTTP and HTTPS. We recommend that you use HTTPS where possible as it permits the Hexcast client web application to use a separate background process to process the audio rather than sharing the same process responsible for rendering the page. HTTP connections are supported as a fallback to maximise compatibility between Hexcast and client devices and should be used if HTTPS cannot be used.

Click About on the web client’s button bar to open the Device Info view. This screen brings together information about the device, its audio configuration and the current stream. It is useful when checking a connection, comparing playback across devices or gathering details for troubleshooting.

Hexcast can support up to six simultaneous connected web client devices for a single session. A web client device is either a Smartphone, Laptop, Tablet or TV.

There are two methods to connect a device:

As mentioned prior, Hexcast offers two protocols for when making a connection. Namely HTTP and HTTPS. We suggest using the HTTPS link as it allows the audio and data inflator to run in low-latency mode in a background thread. HTTPS is required to run the Hexcast web client in a secure context to access lower-level audio capabilities of the browser, resulting in lower latency, thus a better user experience.

On first use, using a browser on your Phone, Tablet, etc you will notice your connection is not private warning when accessing the link via HTTPS. Proceed by clicking through to Advance accept the risk. Hexcast generates a Self-signed Certificate to be used purely for LAN connections and does not serve audio data across the internet.

The setting modal screen allows you to configure Hexcast’s internal web server to serve the web app and audio stream. The majority of users will not find much use for this screen as it contains mainly advanced options to tune Hexcast functionality.

The section below details the options along with their purpose:

Hexcast includes a built-in high-performance resampler that ensures your audio is accurately streamed to any connected device, even when sample rates differ between your DAW and the playback target.

When a device connects via the browser interface, Hexcast automatically negotiates the optimal streaming configuration by detecting the device’s current sample rate. Based on this negotiation:

This negotiation is handled independently for each connected client, allowing playback across devices at different sample rates in real-time.

Hexcast supports a wide range of common and high-end sample rates. Testing has confirmed successful playback up to 384 kHz in Windows and macOS systems, depending on browser and OS capabilities. Keep in mind that browser-based streaming relies on the system’s shared audio environment (WASAPI/Core Audio), which may limit playback rates compared to native ASIO performance.

In the event that you decide to assign new port numbers for Hexcast’s web server you may encounter a port clash with another service. Hexcast will check that the port is available on your system upon save. In the event that a conflict is detected, Hexcast will offer to find a suitable alternative for you. The following modal window is presented when a conflict arises. Answering ‘Yes’ will engage the port hunter and resolve your conflict. Answering ‘No’ will rollback your port changes to their original value.

To install a self-signed certificate on macOS, you can follow these steps:

After following these steps, your self-signed certificate should be installed and trusted on macOS.

To install a self-signed certificate on Windows, you can use the following steps:

By following these steps, your self-signed certificate should be installed and trusted on Windows.

This typically occurs under the following conditions:

There will always be some latency due to the nature of network technology/broadcasting. However, it is possible that the web client falls out of sync so much it diminishes the usefulness of Hexcast. By clicking the SYNC button on the Hexcast web client button bar will cause the web application to clear its internal buffer and resync with the DAW.

Hexcast can support up to six devices connected simultaneously. The system will prevent the 7th web client device from joining the session to prevent Hexcast’s internal server from being overwhelmed.

This occurs when you update the Hexcast plugin to a new version but you have not refreshed the page on your client device creating a version mismatch between the plugin and Hexcast client. To remedy this, simply refresh the browser on the client device and the web application should update to the latest version that the plugin serves.

This typically occurs under the following conditions:

This issue is commonly encountered on iOS devices when the physical mute switch is enabled, even though the web client shows a healthy signal and connection.

Tested on iPhone 6, iPhone 14 Plus, and iPhone 16 Pro Max (physical devices and simulators).

This issue can occur if the installed plugin format is incompatible with the capabilities of older DAWs such as Cubase 11.

This typically occurs under the following conditions:

This typically occurs under the following conditions:

This plugin requires graphics hardware and compatible drivers supporting OpenGL 3.3 or later. Integrated graphics are supported; a dedicated graphics card is not required. Please ensure that your system meets these requirements and that compatible graphics drivers are installed.

Hexcast uses information collected from your hardware to generate Licence Key Activation, so any substantial changes to the system will require a new activation code to be issued.

If you sign in to hexmarkrecords.com using your account credentials, navigate to the My Account section and under Licences you will see your licence information.

There should be an information box allowing you to regenerate an activation code. Click that button and begin the authorisation process again from the plugin window.

If you see the modal above you have multiple copies of Hexcast running on the system. Only one instance of Hexcast can run on a single system at any one time, independent of which host is running. Close any other instances of Hexcast down on your system, whether it be on a different channel or a different DAW. Hexcast exclusively uses the selected ports on a system thus cannot support multiple instances.

The HTTP and HTTPS port numbers should fall within the range of 1024 - 65536 and not be considered a restricted port.

This Agreement is between you and Hexmark Records Ltd, registered company number 10933357, of Wisteria, The Grange Barn, Pikes End, Pinner, London HA5 2EX, United Kingdom ("Hexmark", "we", "us" or "our").

"You" means the individual or legal entity acquiring the licence. If you accept on behalf of an entity, you must have authority to bind that entity. Acceptance does not automatically bind its affiliates.

"Software" means the proprietary Hexcast software we supply, including native plug-ins, the browser application, JavaScript, workers, WebAssembly components, proprietary assets, documentation and updates supplied under this Agreement. Third-party components are addressed in section 11.

"Licence Details" means the licence duration, authorised users, installations and usage limits expressly agreed and made available when your licence is supplied. They do not include restrictions introduced later without agreement. Technical limits described in the documentation are not, by themselves, additional purchased-licence limits.

This Agreement covers paid licences and trials acquired from us or an authorised reseller. A reseller or merchant of record may separately govern the purchase, payment and refunds; this Agreement governs the Software licence and does not remove rights under that purchase contract.

By expressly accepting this Agreement, or installing or using the Software after this Agreement has been made available to you with a reasonable opportunity to read it, you agree to its terms. If you do not agree, do not install or use the Software and contact the seller about your applicable cancellation or refund rights.

An existing licence is not retrospectively replaced merely because we publish this version. Changes to an existing agreement require an effective agreement with you in accordance with applicable law. An update does not, by itself, reduce previously agreed licence rights.

Subject to this Agreement and the Licence Details, we grant you a non-exclusive licence to install and run the Software on devices under your control and to use its intended functionality, including within compatible digital audio workstations (DAWs) and through connected web browsers.

The licence is personal to the licensed individual or entity. You may allow the authorised users identified in the Licence Details to operate the Software. If the Licence Details do not identify additional users, they do not create a separate licence for another person to install or operate the native plug-in independently. You may allow collaborators and clients to listen through the intended browser connections within your authorised Hexcast session. Take reasonable steps to ensure that users you permit to access your licensed session comply with the applicable restrictions in this Agreement.

You may use the Software for personal and professional audio work, including paid mixing, mastering and other work for clients. You may distribute your own audio and project content without licensing that content to us.

You may make the copies reasonably necessary for authorised installation, execution, browser loading, caching and backup. You may configure the Software, use documented customer integrations, manage documented network and certificate settings, and perform ordinary compatibility, playback, latency and performance checks for your permitted use. We may also authorise troubleshooting, support, integration or security-research activities in writing.

The licence continues for the duration agreed in the Licence Details, or until terminated under section 14 if no expiry was agreed. Trial use is subject to the trial period and limits disclosed when the trial is supplied. Updates and support are included only to the extent agreed when supplied; this Agreement does not promise an unspecified support period or future feature set.

You may not transfer or sublicense the Software licence without our written permission, except to the extent applicable law prevents that restriction. Supported reinstallation, licence recovery and hardware migration within your licence are permitted.

Every restriction in this Agreement, including restrictions on analysis, competition, automated extraction, AI use, confidentiality and technical controls, is subject to this section. Nothing in this Agreement prohibits or restricts an activity to the extent that applicable law prevents that prohibition or restriction.

In particular, this Agreement preserves a lawful user’s rights to make necessary backups under section 50A of the Copyright, Designs and Patents Act 1988; qualifying decompilation for interoperability under section 50B; and observation, study or testing of program functioning under section 50BA. Terms restricting those qualifying acts are void to the extent provided by section 296A.

Those rights remain subject to their statutory conditions. Interoperability decompilation must be necessary for the permitted objective, be limited to the necessary acts, and comply with the limits on availability, use and disclosure of the resulting information. It does not permit copying substantially similar program expression or other copyright infringement. Observation, study and testing rights apply while performing the acts the lawful user is entitled to perform.

Other applicable mandatory exceptions are also preserved, including qualifying copying for computational analysis for solely non-commercial research under section 29A. Necessary copying or adaptation, including error correction, must be assessed under section 50C and other applicable law; this Agreement does not remove any right that cannot lawfully be restricted.

No prior permission, notification, fee or additional confidentiality undertaking is required for a statutory activity where applicable law does not permit us to impose that condition. You may contact us for interoperability information or support, but doing so is not an additional condition of a mandatory right.

Except as permitted by sections 2 and 3, separately authorised by us in writing, or permitted by the applicable third-party licence, you must not:

The intended serving of the browser application to permitted connected devices, use within compatible DAWs, configuration, permitted customer integrations, and creation or distribution of your own audio and project content are not prohibited incorporation, modification, redistribution or hosting.

"Implementation Material" means proprietary material forming part of the Software, including source and object code, source maps, code representations of algorithms and data structures, internal implementation documentation, protocol implementation code, and proprietary user-interface assets. It does not include your content or third-party material licensed separately, and this definition does not assert ownership of unprotected ideas, functionality, standards or information.

Subject to section 3 and the permitted use and authorisations in section 2, you must not reverse engineer, decompile or disassemble the Software; decode, reconstruct or attempt to discover its source code; or inspect, analyse or extract Implementation Material to reproduce or reuse the proprietary implementation outside your licence.

Delivery of JavaScript, other source-like code or Implementation Material to a browser, client device or runtime does not transfer ownership or grant rights to modify, publish, redistribute or reuse it beyond this Agreement or applicable law. Readability, browser developer tools, minification, obfuscation, source maps and the absence of an access control do not enlarge the licence.

These restrictions do not prohibit the ordinary browser and diagnostic activities reasonably required for permitted use or authorised support, or any activity preserved by section 3.

Subject to section 3, you must not use Implementation Material copied or extracted outside your licence, our Confidential Information outside its permitted purpose, or material obtained through an act prohibited by this Agreement to develop, reproduce or assist a competing or substitute implementation of the Software.

You must not use automated tools to harvest or reconstruct Implementation Material outside your licence, or systematically capture internal program material for those prohibited purposes.

You must not supply the Software or proprietary Implementation Material as training data, a training corpus, embeddings or another development input for software or AI systems intended to reproduce its proprietary implementation or provide a competing or substitute implementation, except where we authorise that use or section 3 applies.

This section does not prohibit independent development that does not misuse protected material or Confidential Information; mandatory statutory activities; permitted customer integrations; ordinary compatibility or performance testing; truthful product reviews; or use of your own audio and project content with other software or AI tools. It does not claim exclusive rights over functionality, ideas or knowledge lawfully obtained through activities that applicable law protects.

Subject to sections 2 and 3, you must not disable, evade, falsify or interfere with licensing, activation, authentication or security controls; falsify activation credentials or device information to obtain unauthorised access; or defeat agreed installation, authorised-user or trial limits.

You must not publish, sell or share licence keys, activation codes or account credentials to enable unauthorised use. Take reasonable care to protect them and notify us promptly when you become aware of their unauthorised use. Access by authorised users must remain within the Licence Details and any supported account-access arrangements.

Documented licence recovery, reinstallation, hardware migration, network configuration, browser permissions and certificate export or import are permitted. An activation failure does not, by itself, establish a licence breach; contact support to resolve it. We will not treat the exercise of a mandatory statutory right as a breach or a ground for suspension.

The Software is licensed, not sold. Hexmark and its licensors retain their respective intellectual-property rights in the Software and in updates and modifications they supply. No ownership transfers through installation, download, access or browser delivery. Rights not expressly granted or preserved by law are reserved.

You retain your rights in your audio, recordings, project files, settings and independently created material. Use of the Software does not give us ownership of that content or make it a derivative of the Software merely because Hexcast processes, streams or stores it.

This Agreement does not automatically assign to us rights in separately authored customer contributions, independent integrations or modifications. Any authorised development arrangement requiring an assignment must address ownership expressly in an appropriate separate agreement. This does not authorise modifications prohibited elsewhere in this Agreement or affect our rights in the underlying Software.

"Confidential Information" means non-public technical or business information we disclose to you in confidence and identify as confidential, or that a reasonable recipient would understand to be confidential in the circumstances. This may include non-public source code, unreleased designs, internal technical documents or restricted support disclosures.

Use Confidential Information only for the authorised use, integration or support for which it is disclosed, and protect it with reasonable care. You may disclose it to authorised personnel and professional advisers who need it for that purpose and are subject to appropriate confidentiality duties.

Confidential Information excludes information that becomes public without a breach of duty, was already lawfully known without restriction, is independently developed without use of the disclosure, or is lawfully received from a third party without restriction.

Software or JavaScript is not Confidential Information solely because it is delivered with a proprietary notice. Copyright protection and applicable licence restrictions remain separate from confidentiality.

Disclosure required by law or a competent authority is permitted. Where lawful and practicable, give us advance notice and limit disclosure to what is required. This section does not restrict mandatory statutory rights, protected disclosures or reporting to a regulator or law-enforcement authority.

Activation and related services may require account information and device identifiers. Any collection and use of personal information must comply with applicable data-protection law and the privacy information made available for the relevant product or service. The published privacy policy is available at https://hexmarkrecords.com/policy/privacy.

This Agreement is not blanket consent to collect information in any manner, to use support material for unrelated purposes, or to send marketing. Optional analytics and marketing remain subject to the applicable choices and legal requirements. Before sending support logs or project material, remove information you do not wish to share where practicable; we will request only information reasonably needed for the support purpose.

Third-party components remain subject to their applicable licences and notices supplied with the Software. If this Agreement conflicts with rights granted under a third-party licence, that licence governs the relevant component. It does not grant rights in Hexmark’s separate proprietary code. Nothing here claims ownership of a third party’s material or restricts rights that its applicable licence grants you.

This Agreement governs the Software licence alongside the Licence Details and any expressly agreed written variation. The Licence Details define the commercial scope described in section 1; they do not silently override the protections in section 3. A written variation expressly agreed by both parties may govern the matters it specifically addresses, subject to mandatory law and third-party rights.

The Hexcast Proprietary Licence (HPL) notice and source, browser and package notices summarise ownership and refer to this Agreement. They are not separate licence grants or additional warranty exclusions. A notice does not change the Agreement you accepted.

Website and purchase terms may govern their respective services and transactions, but do not by themselves enlarge the Software restrictions or retrospectively replace this Agreement. Any inconsistency affecting mandatory rights is resolved in favour of those rights.

If you are a consumer, nothing in this Agreement excludes statutory rights concerning digital content or services. These may include rights that content be of satisfactory quality, fit for an agreed purpose and as described, and applicable rights to repair, replacement, price reduction or refund. Cancellation and refund rights are governed by applicable law and your purchase contract; this Agreement does not make them conditional on returning materials where the law does not permit that condition.

For business customers, we will exercise reasonable care and skill in services we agree to provide and will comply with any express written product warranties. Subject to those obligations and section 13, other warranties or terms implied by law are excluded only to the extent their exclusion is lawful and reasonable.

We do not promise that the Software will be free of every error, operate with every device, DAW or network, or meet requirements beyond its agreed description and specifications. This does not override express commitments or statutory obligations. You should keep appropriate backups of your audio and project content.

Nothing in this Agreement excludes or restricts liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any liability, obligation, right or remedy that cannot lawfully be excluded or restricted.

If you are a consumer, we are responsible for loss or damage that is a foreseeable result of our breach of this Agreement or failure to use reasonable care and skill. We do not exclude remedies that the Consumer Rights Act 2015 or other applicable law makes available to you. The business limitations below do not apply to consumers.

For business customers only, subject to the first paragraph of this section and to the extent lawful and reasonable, we are not liable for indirect or consequential loss, or loss of profits, revenue, anticipated savings, business opportunity or goodwill. Our total liability arising out of or in connection with the affected Software licence is limited to the amount you actually paid for that licence. This limitation remains subject to applicable reasonableness requirements and does not limit a remedy that cannot lawfully be limited.

You are not required to indemnify us merely because you legitimately use the Software. Each party remains responsible for its own breaches and liabilities under applicable law; this Agreement does not impose a general indemnity for all claims connected with your use.

You may terminate your licence at any time by notifying us and stopping use. Voluntary termination does not itself create a refund entitlement, but does not remove any refund or cancellation right you otherwise have.

We may terminate for a material breach by written notice. If the breach can be remedied, we will identify it and give you at least 14 days to remedy it before termination. We may terminate immediately by written notice for deliberate unauthorised distribution, deliberate circumvention, or a material misuse of intellectual property or Confidential Information that cannot be remedied.

Where reasonably necessary to prevent an ongoing material breach or security threat, we may temporarily suspend affected activation or service access. Suspension must be proportionate and limited to what is reasonably necessary. We will explain the grounds as soon as reasonably practicable, review them promptly, and restore access when they are resolved. You may contact us to challenge or resolve a suspension. Exercise of a right preserved by section 3 is not a ground for suspension or termination.

On expiry or lawful termination, stop using and uninstall the Software, cease making it available to others, and delete copies and proprietary extracts you are no longer entitled to retain. Retention required by law is permitted if the retained material is protected and not used to continue operating the Software. Independent rights under applicable law or third-party licences remain unaffected.

Termination does not transfer your content to us or require deletion of your audio or project files. Accrued claims and mandatory consumer remedies remain unaffected.

We will not use withdrawal of a related service alone to revoke an otherwise continuing paid Software licence. If we discontinue an activation service required for its continued use, we will make reasonable arrangements to support continued lawful operation or provide remedies required by the applicable contract and law. This does not authorise bypassing controls without permission or a legal entitlement.

Unauthorised copying, distribution, circumvention or misuse of Confidential Information may cause harm that damages alone cannot adequately remedy. We may seek an injunction or other relief available under applicable law; the court determines whether relief is appropriate. Contract breach is not, by itself, a criminal offence.

Either party may pursue remedies available for a breach in the circumstances, without double recovery for the same loss. This Agreement does not guarantee an injunction, a particular damages award or recovery of legal costs.

Intellectual-property ownership, restrictions on retained material, confidentiality for information that remains confidential, termination consequences, accrued rights, applicable liability provisions, remedies and dispute resolution survive expiry or termination to the extent relevant. Survival does not authorise continued use of the Software or prohibit acts that applicable law protects.

This Agreement and related non-contractual disputes are governed by the laws of England and Wales. If you are a consumer, this choice does not deprive you of mandatory protections applicable under the law of your habitual residence.

For business customers, the courts of England and Wales have exclusive jurisdiction. Consumers may bring proceedings in any court available to them under applicable mandatory law; nothing here removes that right.

If a provision is invalid or unenforceable, it does not affect the remaining provisions to the extent they can lawfully operate. This does not make an otherwise prohibited restriction enforceable. A delay in exercising a right is not, by itself, a waiver. Statutory rules on interpretation and consumer fairness remain applicable.

This Agreement, the Licence Details and expressly agreed variations set out the Software licence. They do not exclude liability for fraud, override mandatory pre-contract information or remove rights under an applicable purchase contract.
