Build Multi-Key instruments from motion, harmony, and texture inside one living engine.
A generative VST3 and AU plugin for serious sound designers who want some randomness in their music. Every preset holds multiple keys: switch between them on the fly, or let them play in a round robin sequence so one patch moves through its keys on its own.
$39.50 for the plug-in alone, lifetime updates. Or grab the Complete bundle for $59.50 and save $37 vs buying the three packs separately. Sale prices are already on the buttons, no code needed.
We rebuilt the entire CustomTone 1 sound set as a full CustomTone 2 expansion pack — 110 presets with their original waves baked in. It's bundled free with every purchase and waiting in the preset browser the moment you install.
Tone, saturation, and harmonic content. Warm at low values, electric at the top.
Rhythmic density and gate behaviour. Sets how the motion sequencer fires notes.
How freely Evolve mutates state — from frozen to wild — within your locked sections.
Reverb size, modulation depth, and the sense of room around every voice.
Texture, layering, and the silvery tail of every note. Drive, growth, character.
Delay, Wave, Resample, Reverse, Stretch, Filter. Each is a fully independent voice with its own source — drag a sample onto any card and the engine slices, key-detects, and routes. Round-robin them or stack them; pitch-shift one an octave down for a stretch pad while another reverses for a percussive tail.
The Motion panel granularizes the effects themselves. Delay, reverb, reverse, gate, grain, and pitch are chopped into steps and fired by the sequencer, so the effects move like notes instead of sitting on the output.
Eight outer nodes orbit a central hub. Drag to rewire — every connection becomes a live signal path that sequences notes and modulates parameters at the same time. Press Evolve and the engine mutates state under your locks: anything you've pinned stays put, everything else drifts toward something you haven't heard yet.
The Harmony engine analyses any audio you drop and locks the rest of the plug-in to that key — host MIDI, motion-fired chords, every note from every layer is quantised to a scale you actually meant to be in. Pick a mood, pick a scale; the chord cards rewrite themselves.
Every preset is Multi-Key: it holds several keys at once. Switch between them on the fly, or let them play in a round robin sequence and the whole instrument follows, chords, layers, and host MIDI included.
Twenty hand-built factory presets get you playing the moment you load the plug-in — every one comes with its source samples baked in, so the sound travels with the preset. Plus the full Custom Tone 1 Library — 110 presets with their original waves included free (shown up top). Lifetime free updates included.
Four optional expansion packs (Creator Arc, Lucid Dreams, Nostalgia, Shrimp & Grits) sold separately at $19 each. Add all four for 82 more presets and 450+ more baked samples — see below.
Each pack is a set of hand-built presets with their samples baked in — most also ship original MIDI patterns hooked into the engine's motion map. $19 each; licensed to your CustomTone 2 account.

Eight unedited patches straight from CustomTone 2.
CustomTone 2 ships as VST3, AU and, from version 1.0.7, CLAP, on macOS and Windows. All three come from the same engine, so presets, sessions and your sign in are shared across formats. The CLAP build exposes the automatable parameters only, which gives you a shorter, cleaner list in your DAW, and it is the format that makes per note modulation of the Multi-Key engine possible down the road.
One installer per platform puts all three in place. Not sure which to load? AU vs VST3 vs CLAP, explained.
Audio Tech Hub has shipped commercial VST plugins under our own name and a dozen producer brands since 2019. CustomTone 2 is everything we've learned about real-time audio software, generative composition, and plug-in UX — packaged as a tool. If you'd rather build your own instead, we teach the craft directly: our VST development course walks engineers and producers through the full pipeline — JUCE / HISE / FAUST, UI design, DSP fundamentals, store launch, distribution.
Brands we've shipped VST plugins for: MacShooter · Busy Works Beats · Infinit Audio · Producer Sources · StudioTrap · DNX · B Rackz · Killshot · SoundWare · Studiolinked VST · Banana Audio.
One-time purchase. Free updates for the life of the plug-in. Test drive it with our money for the first week.
