Changelog - Ambivalent Instruments

[2.0.3] - 2026-02-24

New Modules

  • AutoPanTremolo: Stereo auto-pan and tremolo effect with morphable LFO waveforms (Sine/Triangle/Saw/S&H), tempo sync via external clock, and adjustable stereo phase
  • Cheby: Chebyshev harmonic generator with 8 independent harmonic sliders (H1–H8), dry/wet mix, and optional soft clip output
  • Seq8: 8-step CV/Gate sequencer with internal tempo (40–200 BPM) and external clock sync (0.25x / 0.5x / 1x / 2x / 4x multiplier)

Fixed

  • Grainer: Fixed implementation bug that was converting input audio to mono.
  • Delay: Fixed typo in panel labeling.
  • All: Reduced processing load through optimization.

[2.0.2] - 2026-02-04

Delay Module

Changed

  • Smoother mode switching: Reduced clicks when changing delay modes
  • Reverse playback refinement: Cleaner reverse repeats and time changes
  • Modulation updates:
  • Reverse mode adds chorus-style movement
  • Octave mode uses tremolo-style movement

Improved

  • Mode button tooltip: Shows MOD knob behavior for each mode

Fixed

  • DelayExpander clock: Stable clock pulses at very short delay times

Grainer Module

Added

  • Freeze buffer persistence: Frozen sample buffer is now saved with your patch and restored on reload

Improved

  • Parameter tooltips: Hover over knobs to see descriptions

Fixed

  • Startup stability: Fixed a crash on startup/exit

Modulo Module

Improved

  • Parameter tooltip: Modulo Value knob shows formula
