.img.xzfile above (~720 MB compressed, ~4–5 GB on the SD card). - Open Raspberry Pi Imager → Choose OS → "Use custom" → select the file.
- Choose your SD card (8 GB+) → Write.
- Insert SD card into your Pi, plug in your touchscreen + sampler, power on.
First boot launches a setup wizard that handles input mode (touchscreen vs mouse — it auto-detects), touch calibration, WiFi, and finishes by checking your USB devices.
What's in v0.1.0
Distribution
- Compa OS image and one-command installer at raredata.net/compa.
Touchscreen UI
- Workspace per device — SP-404 MK2 and Roland AIRA Compact P-6 — with live FX control, kit builder, chromatic keyboard, MPC / Force / Ableton export, and a session view tying everything together.
Push 2 control
- Keys mode: full-screen LCD layout with a piano keyboard, rolling note roll, and chord recognition (Cmaj7, F#m7b5, slash chords, etc.) on both the Push 2 LCD and the touchscreen.
- Chord layout: every pad plays a full chord. 8 columns are the diatonic chord positions (I–vii°+I'); rows are variations (root, +7, 1st inv, 2nd inv, then +1 octave). Tap LAYOUT to cycle chromatic → in-key → chord.
- Arpeggiator across all keys layouts. Encoders control rate, octaves, stab, swing, density, inversion, humanize, accent. Top buttons are pattern shortcuts (UP / DOWN / UP-DN / DN-UP / RANDOM / OFF) + RESTART + HOLD. Tempo follows the P-6's BPM live.
- Top scale buttons (above LCD) and root buttons (below LCD) are direct shortcuts — Major, Minor, Pent, Blues, Dorian, Mixolydian for scales; C–B for roots (Shift+root for the sharp variant).
- SP-404 chromatic mode: Push 2 grid auto-aligns to whichever pad you're playing chromatically.
Setup + updates
- First-boot wizard with mouse auto-detect, touch calibration, and WiFi setup.
- Auto-updater polls every 30 min in the background. When a new build lands, the Settings menu's UPDATES button lights up; one tap shows the changelog in plain English and pulls the update.
