Michele Caserta has released bitcrust, available for $1.99.
A modern polyphonic synthesizer with a SID brain Three oscillators per voice, twelve voices, in-house chip DSP. Universal Purchase for Mac + iPad
bitcrust is a polyphonic synthesizer built around a SID-style voice architecture: three oscillators per voice, up to twelve voices, with ring mod, hard sync, and the pulse-width behaviour that defined a generation of 8-bit sound. 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 hat keep most SID-inspired tools off the major app stores.
Sonically the plugin sits between a chip synth and a odern subtractive. The voice core can still do gritty arp basses, zap leads, and 8-bit percussion, but the surroundina 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 buvs 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 natrix / FX rack ship on both platforms
Features include:
- Voice core: 12-voice polyphony, 3 oscillators per oice, SID-stvle triangle / saw / pulse / noise with harc 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 z), per-voice mod envelope, 8-slot matrix, MID sources (velocity, poly AT, channel AT, mod wheel bitch bend)
- X rack: 6 slots, draq-to-reorder, per-slot bypass nix; 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, JpDown / Random, 6 rate divisions, octave range) MIDI Learn on everv knob, note Hold
- Presets: 113 factory patches across 10 groups, full- netadata save (author, description, tags), Preset Preview audition without committing, A/B snapshot compare, XML import / export
- UI: 6-tab navigation, 14 themes with optiona phosphor / CRT overlays, monitor strip (oscilloscope vectorscope, FFT spectrum, 3D spectrogram, stered 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.)
