32 x 32 Mix Matrix
Create up to 32 independent stereo mixes from the same sources. Each output can have its own blend while strip controls stay predictable.
Mixing, Routing, Processing, Recording
FusionDesk
A Windows software mixer for flexible audio routing, sandboxed VST3 processing, direct recording, and monitor control across ASIO, Windows Audio, and Per-Application Audio Capture - and now plays software instruments live.
Now in Beta-3
Routing Without Hardware Lock-In
Inspired by the matrix-mixer workflow of RME TotalMix FX.
Build independent mixes from the same sources, send them to different destinations, and keep the whole session visible in one dense, console-style interface.
FusionDesk brings that always-visible routing philosophy to the wider Windows audio world: professional ASIO interfaces, standard Windows devices, application audio, VST3 insert chains, snapshots, monitoring, and recording.
Core Features
Everything visible. Everything routable.
ASIO, WASAPI, and PAC
Use professional ASIO channels, standard Windows Audio devices, virtual audio devices (including Dante Virtual Soundcard and other ASIO drivers), and Per-Application Audio Capture in one session.
Sandboxed VST3 Hosting
Third-party plugins are isolated from the mixer. If a plugin crashes or hangs, FusionDesk keeps audio running and lets you reload the slot.
Built-In Recording
Record inputs and outputs to WAV, FLAC, or MP3. Loop capture keeps a rolling buffer so you can export the last moments after they happen.
Control Room Monitoring
PFL, AFL, Solo, listen output routing, monitor processing, LUFS metering, peak holds, and live status readouts sit where you need them.
Native Processing
A built-in suite - parametric EQ, Compressor, Limiter, Tone Generator and Alignment Delay - loaded like insert plugins, with no plugin-host overhead. See the processing suite.
Play Instruments
Load a VST3 instrument plugin on any channel and play it live from your computer keyboard or a MIDI controller, then record the result. See how it works.
Built-In Processing
A full processing suite, before you load a single plugin.
FusionDesk ships with native processors you can load into any input or output slot, just like a VST3 - but with no plugin-host overhead. They save with the session and snapshots, and travel when you copy a channel's chain.
Parametric EQ
Up to 24 bands - Bell, Shelf, Cut, All Pass, Band Pass, Tilt - edited on an interactive curve from 10 Hz to 20 kHz, with a live spectrum analyser behind it. Bypass any band with a right-click, type frequencies as musical notes, and recall Factory or User presets in one click.
Compressor and Limiter
Native dynamics with strip-style gain-reduction metering and a scrolling history graph that shows level and reduction over time - so you can see the compressor catching transients or the limiter just kissing the ceiling. Reset every control to its factory value in one click.
Tone Generator
Seven waveforms - Sine, Triangle, Square, Saw Up, Saw Down, White and Pink Noise - for line-up, calibration and testing. Set frequency, level, and a mix to blend the tone over the channel or replace it entirely.
Alignment Delay
A pure time delay from 0 to 2000 ms - no echo, no effect - to line a channel up against other feeds. Time-align subs to the mains, correct lip-sync, or align a delay tower, with coarse and fine controls and a samples readout.
Play, Don't Just Mix
Play VST3 instruments, live, inside your mix.
Load a VST3 instrument plugin onto any input channel and play it live - from your computer keyboard or one or more MIDI controllers - straight into your mix. No project to set up, no separate DAW to launch just to play an idea.
PC Keyboard or MIDI Controllers
Choose the computer keyboard or a connected controller from a channel's input menu and play. The computer keyboard is polyphonic - hold a full chord, limited only by your keyboard's key rollover. One or more controllers can drive several instruments across different channels at once, each playing independently.
Capture the Take
What you play runs through the same channel and mix as everything else, so you can record the performance with the built-in recorder.
Played at ASIO Latency, In Time
Because FusionDesk already runs at the low buffer sizes live work needs, instruments feel immediate - the same low-latency path your audio takes. Set a global tempo and instruments with tempo-synced arpeggiators, delays, or LFOs follow it.
The Mixer
Designed for people who need to see the whole signal flow.
Input strips, output strips, mix buttons, plugin slots, meters, recording controls, and the Control Room stay on one screen so routing decisions remain visible. Keep your favourite audio sources together, then send them to speakers, headphones, recorders, streams, or call apps as needed.
Use Cases
Built for practical Windows audio rigs.
Audiophile Stereo Listening
Get the best from a two-channel system: switch between DACs and headphone amps, A/B sources instantly, and apply per-output EQ to voice each pair of speakers or pair of headphones to taste.
Studios and Musicians
Build headphone mixes, route DAWs and media players, insert room correction or headphone EQ, play instrument plugins live from a keyboard or controller, and save complete setups as snapshots.
Livestreams and Content Creation
Capture microphones, browsers, games, music players, guests, and comms apps separately, then decide exactly what each destination hears.
Multichannel and Surround
Build a surround or multichannel setup by hand: route each source to the speakers you choose - 5.1, 7.1, or a custom array - and place, level, delay and EQ every channel individually. You mix it manually; FusionDesk gives you the routing and per-output control to do it.
Live and AV Work
Create Main and Monitor mixes, recording feeds, utility mixes, and backup routing from one screen, with live-performance protections for show use.
Voice and Video Calls
Send selected audio sources into a messaging or conferencing app during a call while keeping your own monitor mix separate.
Real Session Tools
The everyday details matter.
FusionDesk keeps setup, routing, plugin choice, and recording checks close to the mixer so you can make changes without losing the session.
Per-Application Audio Capture
Capture browsers, media players, DAWs, messaging apps, and other sources, then route them like any other input.
Plugin Management
Load native dynamics or third-party VST3 plugins, organise favourites, hide plugins you do not use, and keep insert chains ready.
Recording Confidence
Check disk usage, recording rate, remaining time, and estimated full date before committing to a long take.
Audio Quality
Transparent by design.
FusionDesk runs a 32-bit floating-point mix bus with constant-power pan law, calibrated RMS, LUFS and True Peak (dBTP) metering, and adaptive resampling for asynchronous Windows audio sources.
- Frequency Response
- 20 Hz to 45 kHz at 96 kHz, ruler-flat
- THD+N
- 0.0009% through the digital signal path; analogue I/O results depend on your interface
- Phase Integrity
- Stereo null across the full audio band
- True Peak
- dBTP metering catches inter-sample overs a sample-only meter misses
Reliability
The audio doesn't stop.
Plugins crash, drivers hang, shows run long. FusionDesk is built so that none of that takes your sound down - and when something does go wrong, it leaves a plain-language trail you can actually follow.
Sandboxed Plugins
Third-party VST3 plugins run isolated from the mixer. If one crashes or hangs, FusionDesk bypasses it and keeps the audio flowing - then lets you reload the slot without restarting.
Protected Audio Path
The audio stream is defended on every side: denormal numbers that can spike CPU on near-silent signals are handled automatically, diagnostics only ever write between the audio - never in the middle of it - and a faulting plugin drops to clean pass-through. The things that quietly wreck a session are designed out.
Live Performance Mode
For shows, a single mode hardens FusionDesk against mid-set surprises - including pausing diagnostics writes - so nothing competes with audio while you're on.
Pro Audio Scheduling
Plugin processing registers with Windows' Pro Audio scheduling - the same class your ASIO driver uses - so it's far less likely to glitch when other software keeps the computer busy.
Diagnostics
When something does go wrong, you get answers.
Flight Recorder
An always-on, plain-language log of each session - device changes, plugins loaded, crashes, audio stalls, snapshot saves. It runs automatically and costs nothing while idle.
Readable Crash Reports
If FusionDesk ever closes unexpectedly, it writes a companion text file with the version, the error, and the last events - so a crash comes with the story of what led up to it.
Export Diagnostics
One click gathers logs, crash reports, settings and plugin history into a single dated zip you can email. It works entirely offline, and your Windows user name is removed automatically.
Plugin Health
See which plugins have crashed this session and how often, so you can spot an unreliable one at a glance. A crashed plugin is bypassed automatically while audio keeps flowing.
Performance and Scale
Built for big sessions.
FusionDesk uses your whole CPU and keeps large, dense setups workable on the screen you actually have.
Parallel Plugin Processing
Channels are independent, so their plugin chains process simultaneously across your CPU's cores. In testing, a 96-plugin session ran cleanly at a 512-sample buffer, and testers have reported sessions well beyond 100 plugins. It's automatic, with nothing to configure.
Bank View
When you have more channels than fit across the screen, Bank View pages them into equal groups - 2 banks of 16, 4 banks of 8 - with inputs and outputs always lined up. Every channel keeps running in every bank; only what's on screen changes.
