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.

  • Euclidean pattern control
  • Tempo sync and free control
Read full description

BattleFX was created to satisfy the common request of a dedicated plugin for the send effects in Battalion. The famous "Shatter Delay" and "Headspace Reverb" can now be used on any track. We have included a fully-featured set of mix controls, as well as Solo and Mute, so that you can hear or use each portion individually. Included is the Maximize and EQ section from the Master portion of Battalion, which have quickly become a signature sound of the device, and something fans have requested to use elsewhere. Versatile enough to be used as both a utility-tool and full creative effect, it is the right squad-partner to keep always at your side in the field and trenches. In addition, we have added a system for automatically choking the delay and reverb buffers at repeating intervals, including a Euclidean pattern knob. These can be tempo synced or free, controlled independently on reverb and delay, and even nudged slightly off of the beat in either direction. You can use this to create complex, organic ducking patterns, especially in conjunction with a noisy input and the Maximize knob turned up. If this is your first introduction to a piece of Battalion, be sure to check out the full drum synth itself, which includes everything here besides the automatic choke system (as this can be done directly by sidechaining drum hits).
