Turn your iPhone, iPad or Mac into a customizable MIDI controller. Plug in your synth, pick parameters by name, and start playing in seconds. Condukt connects to any class-compliant USB MIDI device. No adapters. No manual CC programming. Just plug in and go. ▸ PLUG AND PLAY Connect your synth via USB-C. Condukt recognizes it instantly. Pick parameters from a list, filter cutoff, oscillator pitch, envelope attack, and you're controlling it. No more digging through manuals for CC numbers. ▸ RUNS IN YOUR AUv3 HOST (NEW) Load Condukt as an Audio Unit inside AUM, Loopy Pro, Logic Pro for iPad, Cubasis or Drambo. It follows host transport and tempo, so every sequencer starts on the host's downbeat. Run as many instances as you like, each with its own board, clock and patch cables, and your host project saves and restores all of it. ▸ SEVEN SEQUENCERS Conduktor, Phrase, Drum, Arpeggiator, Turing Machine, Cartesian and Painter. Draw chords with a finger or Pencil, program a XOX drum grid with polyrhythmic track pages, or let a Turing Machine find the pattern for you. One clock runs them all. ▸ POWERED BY midi.guide Condukt uses the midi.guide open-source database with MIDI definitions for hundreds of synths, drum machines, and effects. Community-maintained and constantly growing. ▸ BUILD YOUR OWN BOARDS Create custom control surfaces tailored to your workflow. Sequencers, faders, crossfaders, recall buttons: arrange them however you want. Save multiple boards for different setups. ▸ DO WHAT YOUR HARDWARE CAN'T - Add multiple LFOs to synths that only have one - Shape any parameter with the new Step Modulator - Control the same parameter across multiple tracks with a single fader - Instant snapshot recall for live performance - Sophisticated generative sequencers ▸ MULTI-DEVICE CONTROL One board can control multiple synths simultaneously. A single "Filter" fader can adjust cutoff on your Minifreak, Digitakt, and Moog at the same time. ▸ PERFORMANCE LAYOUTS Switch between layouts on the fly. Page 1 for sound design. Page 2 for performance. Page 3 for mixing. All within the same board. ▸ SNAPSHOT RECALL Store and recall control settings instantly. Tap and hold to save. Quick tap to restore. Perfect for live sets. Add crossfaders and morph between saved scenes. ▸ FULLY THEMEABLE Condukt looks as good as it works. Custom themes make your controller visually distinctive, whether you're performing on stage or filming content. ▸ WORKS WITH Elektron (Digitakt, Syntakt, Octatrack, Analog Four, Model:Cycles, Model:Samples), Arturia (Minifreak, Microfreak, MiniBrute), Moog (Subharmonicon, DFAM, Mother-32, Matriarch), Teenage Engineering, Novation, Korg, Roland, Sequential, and hundreds more. ▸ MADE FOR MUSICIANS Built by synthheads for synthheads. We've been working on this project for 5+ years, and Condukt is the app we always wanted. Start free with the Hello board, subscribe monthly, or buy Lifetime once and be done. No account required.

GrainHeads is a granular synthesizer that turns any sound into something entirely new. Built for sound designers, musicians, and experimental producers who want deep, hands-on control over texture and motion. Multi-source granular engine Load material into four sample slots and deploy independent playheads — each targeting its own source. Blend, crossfade, or dynamically switch between samples using modulation. The result: rich, multi-layered textures that evolve continuously without repetition. Shape every grain Each playhead carries a full set of granular parameters — position, scan speed, grain size, pitch, chance — plus a drawable grain envelope. Sculpt transient character using splinter or Bézier curves for anything from soft clouds to sharp, percussive fragments. Modulate everything, from everywhere A summing modulation matrix lets multiple sources target the same parameter simultaneously. Assign LFOs, envelopes, and sequencer lanes to virtually any control — including sample slot selection, filter cutoff, and even other LFOs. Filter envelopes add per-step timbral motion in Sequencer mode. Sequencer with parameter lanes Go beyond note patterns. The step sequencer locks any parameter per step — pitch, position, filter, grain size — with polyrhythmic lengths and clock divisions. Each playhead runs its own sequence independently. Macros for expressive control Four macro axes map multiple parameters to simple X/Y gestures — Time Smear, Spatial Bloom, Degradation, Complexity. Combined with the 4-finger 2D touch pad controlling up to 8 parameters, GrainHeads becomes a performance instrument. Effects that reshape the signal A re-routable effects chain includes delay, reverb, lo-fi degradation, and filtering — with adjustable signal flow so effects interact in the order you choose. Key Features • AUv3 instrument and effect plugins — use standalone or inside your DAW • Up to 8 independent granular playheads • 4 sample slots with per-playhead source selection • Drawable grain envelope (splinter / Bézier curves) • Summing modulation matrix — multiple LFOs, envelopes, and sequencer lanes per target • LFO-on-LFO modulation for deeply nested movement • Step sequencer with parameter locking and polyrhythmic clock divisions • Filter envelope per step (Sequencer mode) • Per-playhead dual Moog-style ladder filter (self-oscillating, with overdrive) with link and mirror modes • 4 macro axes (X/Y pads) for multi-parameter gestures • Re-routable effects section (delay, reverb, lo-fi, noise, limiter) • Scale quantization — chromatic, major, minor, and exotic modes • Dice — one-tap randomization for instant inspiration • Ableton Link • Import/export presets • Customizable look and feel PRO version unlocks loading external samples and microphone recording. GrainHeads turns granular synthesis into a hands-on instrument — not a menu-diving exercise.
