Version History
Redesigned Interface
A ground-up redesign: a larger, lighter raised-panel canvas with one unified top bar — settings, INIT, presets, randomize, A/B, undo and redo. The combined MOD row puts LFO 1 / 2 and ENV 1 / 2 side by side. SPREAD is now STEREO, REVERSE is a rotary knob, and FREEZE sits on the waveform bar.
Envelope Modulation
Two ADSR envelopes join the two LFOs in the MOD row. Drag an envelope onto any knob to assign modulation, with AUDIO (fires when the input crosses a threshold) or GRAIN (fires on every grain) trigger modes. ENV 1 green, ENV 2 magenta; one-shot and one-sided.
Step Mode
Turn the grain visualizer into a rhythm sequencer — 4, 8, or 16 steps with note divisions down to 1/128, per-step subdivisions, and right-drag painting across steps. Works alongside EVEN / DOT / TRIP for swung patterns.
A/B Compare
Two independent slots in the top bar — click A/B to switch between two versions of your sound. Each slot keeps its own preset and edits; loading a preset or hitting INIT only affects the active slot. Right-click for Copy A to B, Copy B to A, or Swap.
Undo / Redo
Ctrl/Cmd+Z to undo, Ctrl/Cmd+Y (or Shift+Z) to redo — up to 64 steps covering knob moves, FX rack changes, modulation routes, rhythm edits, A/B flips, preset loads, RND and INIT.
140+ Presets & Favorites
140 factory presets across 14 categories — including two new ones, Evolving and Modulated, that use LFO and envelope modulation. Star your favorites, browse by category in the new preset panel.
Main Filter Q + Slope
The main HP/LP filters now have resonance and a 12 / 24 dB-per-octave slope switch. Use the new Q knobs under the cutoffs, or drag vertically on the spectrum ring to set Q.
A 6th Knob on Every FX
All 10 FX gain a 6th control — Bitcrusher TILT, Chorus / Reverb / Delay WIDTH, Phaser STAGES, Flanger STEREO, Distortion OUTPUT, Tremolo SKEW, Utility TILT, Filter SLOPE. Defaults are neutral, so existing presets sound identical.
Hover Help
Hover any control for a moment and a short contextual description appears — replacing the old tooltips and info-card buttons. Toggle Hover Info off in the settings panel.
Settings Panel
Redesigned with a new GUI Size option (snap to 75 / 100 / 125 / 150%) and a Visualizers toggle that turns off animations to save CPU.
