The DSP is an in-house, clean-room implementation written from the public MOS 6581 register map and general DSP literature — not an emulator port — so bitcrust sounds SID-adjacent without inheriting the license constraints that keep most SID-inspired tools off the major app stores. Sonically the plugin sits between a chip synth and a modern subtractive. The voice core can still do gritty arp basses, zap leads, and 8-bit percussion, but the surrounding architecture — three LFOs, a per-voice modulation envelope, an 8-slot modulation matrix, and a 6-slot post-SID FX rack with drive, bitcrusher, tempo-synced delay, chorus, reverb, compressor, and limiter — extends it into pad, keys, and texture territory. Universal Purchase: one price buys the Mac Standalone plus the iPad AUv3. The iPad build is a co-equal target, not a downscale — the full 113-preset factory library, all 14 themes, and the complete mod matrix / FX rack ship on both platforms. Voice core: 12-voice polyphony, 3 oscillators per voice, SID-style triangle / saw / pulse / noise with hard sync and ring mod, per-VCO ADSR Filter: global VCF (LP / BP / HP) with live curve, selectable 6581 / 8580 chip model, Vintage vs. Modern oscillator mode Modulation: 3 global LFOs (7 shapes, host-sync or Hz), per-voice mod envelope, 8-slot matrix, MIDI sources (velocity, poly AT, channel AT, mod wheel, pitch bend) FX rack: 6 slots, drag-to-reorder, per-slot bypass / mix; effect types Drive (5 modes), Bitcrusher, Delay (tempo-sync), Chorus, Reverb, Compressor, Limiter — every FX parameter is a modulation destination MIDI: 16-step sequencer, arpeggiator (Up / Down / UpDown / Random, 6 rate divisions, octave range), MIDI Learn on every knob, note Hold Presets: 113 factory patches across 10 groups, full-metadata save (author, description, tags), Preset Preview audition without committing, A/B snapshot compare, XML import / export UI: 6-tab navigation, 14 themes with optional phosphor / CRT overlays, monitor strip (oscilloscope, vectorscope, FFT spectrum, 3D spectrogram, stereo field), QWERTY note typing from any tab Mac: Standalone app with universal binary (Apple Silicon + Intel). iPad: AUv3 extension plus a Standalone for headphone jamming. A supported AUv3 host is required for in-DAW use on iPad (GarageBand, Logic Pro for iPad, AUM, Cubasis, etc.).

Sweep, detune, or animate hard-sync tones from any source. - Modulated knobs show a live arc on the value ring indicating where the modulation is pushing the value. Direction shows polarity, length shows depth. - Per-step trigger probability in the sequencer. Each step has a 0 to 100% chance of firing. The pattern randomizer (dice button) now fills probability across the full range too. ### 1.0.7 — 2026-05-05 - Fixed-velocity toggle for the keyboard and grid. Lock either surface to a single velocity, independently. Tap the new VEL button in the footer for the keyboard panel; grid uses its setup popover. Doesn't affect external MIDI. - Sliding across grid pads now plays each pad at your initial tap's velocity. Swipe direction no longer encodes loudness. - Hold latch keeps the played key or pad highlighted until the latch releases. - Mod matrix: each source row's activity glow now reflects only that source, even when multiple sources drive the same destination. ### 1.0.0 — 2026-04-23 No release notes. ## More apps by Michele Caserta - [Untracker](https://appshunter.io/ios/app/untracker/id6760624490) - [Earshot — Ear Training](https://appshunter.io/ios/app/earshot-ear-training/id6765878618) All apps by Michele Caserta: https://appshunter.io/developer/1885379520 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
