A Sneak Peek into CME’s iWA Technology Development

Hello i m impatient to be able to do tests if there is a need for a beta tester I am willing

Proposal: iWA as a Modular Wireless Audio–MIDI Network for Musicians
Compact Nodes + Audio–MIDI Hubs + iWA Core + Routing Software = WIDiWA: Wireless MIDI-Audio Musical Network

Dear CME iWA Team,

Thank you for inviting the community to help define the future direction of iWA.

In my opinion, the most valuable opportunity is not to build only one wireless audio product for one specific purpose. iWA could become the foundation of a modular short-range wireless audio and MIDI ecosystem for musicians, studios, live stages, educators, content creators, and musical hardware manufacturers.

The main problem iWA should solve is simple:

Replace short-distance audio and MIDI cabling between instruments, microphones, mixers, audio interfaces, monitoring systems, mobile devices, and other musical equipment—without sacrificing sound quality, stability, or real-time performance.

The current strengths of iWA appear especially suitable for this task: uncompressed stereo HD audio, sub-millisecond wireless latency, high interference resistance, and operation over relatively short distances with minimal obstacles.

This is exactly the environment found around a musician, a pedalboard, a keyboard rig, a studio desk, a mixing console, a recording rack, or a live stage.

1. A universal modular product family

iWA Compact Nodes

Small portable transmitter, receiver, or transceiver modules.

Two compact nodes could be used directly as a simple one-to-one wireless link:

– instrument to amplifier, mixer, or audio interface;
– microphone to mixer or recorder;
– stereo keyboard to mixing console;
– mixer output to active speakers;
– mixer AUX output to headphones or an IEM receiver;
– audio interface output to studio monitors;
– mixer or instrument output to an iPhone, tablet, camera, or portable recording device.

The same compact nodes should also be able to connect to larger multi-channel iWA hubs.

Ideally, the compact node would contain the common iWA radio, digital audio, routing, synchronisation, battery, and control platform, while different detachable adapters would provide the required analogue or digital connections.

Possible adapters could include:

– dual XLR/TRS combo microphone and line input, with gain control and optional 48 V phantom power;
– Hi-Z instrument input for guitar, bass, pickups, and other instruments;
– stereo balanced line input or output;
– XLR microphone input;
– headphone and IEM output with a high-quality low-impedance amplifier;
– 3.5 mm stereo input or output;
– USB-C class-compliant audio and MIDI connection for computers, tablets, and phones;
– optical or other digital audio formats where useful.

This approach would keep the main module compact while avoiding compromises between microphone, instrument, line-level, and headphone electronics.

iWA Audio–MIDI Hubs

Desktop or 19-inch rack-mounted multi-channel transmitter, receiver, or transceiver units.

A hub could connect to many compact iWA nodes in different combinations.

For example:

– eight instruments and microphones transmitting to one rack receiver near the mixer;
– one multi-channel transmitter sending several personal monitor mixes to musicians;
– several stereo keyboards connected wirelessly to a studio audio interface;
– multiple compact receivers connected to powered speakers or monitor systems;
– a central studio hub communicating with instruments, controllers, headphones, recorders, and mobile devices.

Different hub models could be optimised for different roles:

– multi-channel input hub;
– multi-channel output hub;
– personal-monitoring hub;
– universal bidirectional hub;
– studio hub with USB audio interface functionality;
– live-performance hub with redundant power and professional locking connectors.

The hub could include paired stereo XLR/TRS combo connections, balanced XLR or TRS outputs, headphone outputs, MIDI DIN, USB MIDI, and native WIDI integration.

In the future, the hub could also act as a bridge to Dante, AES67, USB Audio, or other professional audio networks. iWA would handle the final low-latency wireless connection between the central system and nearby musicians or devices.

iWA Core for Manufacturers

An embeddable iWA Core would allow musical hardware manufacturers and independent developers to integrate iWA directly into:

– digital pianos and keyboards;
– synthesizers;
– mixers;
– audio interfaces;
– amplifiers;
– active speakers;
– guitar processors;
– pedalboards;
– microphones;
– wireless headphones and IEM systems;
– educational musical devices;
– portable recording equipment.

This could follow the successful philosophy of WIDI Core, but for professional low-latency audio.

2. More than wireless cables

The long-term opportunity is to make iWA a local low-latency musical network, not only a collection of paired transmitters and receivers.

The system should support several connection models:

– one transmitter to one receiver;
– one transmitter to multiple receivers;
– multiple transmitters to one hub;
– multiple transmitters to multiple receivers;
– bidirectional communication;
– point-to-point links;
– hub-based networks;
– direct device-to-device operation without a hub.

A user should be able to create named audio routes such as:

– Keyboard L/R → Mixer Channels 1–2;
– Vocal Microphone → Mixer Channel 3;
– Mixer AUX 1 → Musician 1 IEM;
– Mixer AUX 2 → Musician 2 IEM;
– Main Mix → iPhone Recording Input;
– Teacher Audio → Student Headphones;
– Metronome → Drummer Only.

The routing application could show connected devices, signal levels, battery status, wireless quality, buffer status, latency, and channel assignments.

It would also be valuable to save complete routing configurations as scenes:

– rehearsal;
– concert;
– recording;
– teaching;
– streaming;
– mobile setup.

The system should continue working locally without requiring a cloud service or permanent internet connection.

3. Combining audio and MIDI

One of the most powerful possibilities is to combine iWA and WIDI inside the same product family.

Audio and MIDI should remain separate protocols internally, but they could be presented to the musician as one logical connection.

For example, a wireless keyboard connection could carry:

– stereo audio;
– MIDI notes and controllers;
– program changes;
– transport commands;
– device control;
– synchronisation information.

A single named connection such as “Stage Piano” could therefore represent both its audio channels and MIDI ports.

An iWA Audio–MIDI Hub could become the central connection point for an entire keyboard rig, an electronic drum setup, a guitar system, a studio desk, or an educational workstation.

This would remove not only audio cables, but also MIDI cables, USB extensions, adapters, and complicated routing between multiple independent wireless systems.

4. Important real-world requirements

For professional musicians, the most important specification is not only radio latency, but complete end-to-end latency:

analog or digital input → conversion → wireless transmission → buffering → conversion → analog or digital output.

The system should provide predictable and clearly documented end-to-end latency.

Other important requirements would include:

– stable multi-channel synchronisation;
– low jitter;
– automatic frequency and interference management;
– clear signal-loss behaviour;
– safe muting instead of loud digital artefacts;
– reliable reconnection;
– battery and charging status;
– optional channel encryption;
– channel naming and device identification;
– local diagnostics for RF quality and audio-buffer behaviour;
– robust performance when several systems are operating nearby;
– simple pairing for basic users and advanced routing for professional users.

For personal monitoring, the headphone receiver should include a high-quality amplifier suitable for sensitive and low-impedance IEMs.

5. Recommended first implementation

A practical first product could be a modular iWA Compact Node system.

The first generation could include:

1. A compact stereo transmitter/receiver pair for direct one-to-one use.
2. Detachable adapters for stereo line, instrument, microphone, headphones, and USB-C.
3. A small four- or eight-channel desktop/rack iWA Hub using the same protocol.
4. Basic local routing and diagnostics through the iWA web application.

This would allow CME to test several important workflows without developing a very large system immediately:

– instrument to mixer;
– microphone to mixer;
– mixer AUX to IEM receiver;
– audio interface to headphones or monitors;
– mixer output to mobile recorder;
– several compact nodes connected to one central hub.

The direct compact pair would be useful and affordable on its own, while the hub would demonstrate that every compact node is already part of a larger ecosystem.

6. The larger vision

The final vision is a local musical network in which audio, MIDI, control, monitoring, and synchronisation can move between nearby devices with extremely low latency.

A musician could arrive with an instrument and one compact iWA node. The node could automatically connect to the venue hub, restore the correct audio and MIDI routing, receive a personal monitor mix, and become part of the complete stage system.

The same node could later be used in a home studio, rehearsal room, classroom, mobile recording setup, or content-creation workflow.

This is why I believe the universal modular form factor is important.

A compact node should not be limited to one permanently defined role. A rack hub should not be limited to one proprietary group of receivers. Every part should be able to participate in the same iWA network in different combinations.

In this model, iWA is not merely a wireless replacement for one audio cable.

It becomes the physical layer of a flexible, low-latency wireless musical environment.

Thank you for opening the development process to the community. I would be very interested to see iWA evolve in this modular direction.
