- env~ is a cyclone external not available on board's Pd 0.55
- Replace with line~ + *~ 0.0055 for velocity-scaled AR envelope
- Fix stripnote outlet 1 (gate trigger) connected to envelope instead of outlet 0 (pitch)
- Change dac~ to dac~ 1 for mono output matching -outchannels 1
- Envelope: attack ~50ms, release ~50ms, sustain scaled by velocity
hsl GUI objects don't initialize in -nogui mode, causing
cutoff at 0 Hz and volume at 0 → no audio output.
Use loadbang + float for headless-safe initialization.
- Create skills: rego-pd-validator, usb-gadget-configfs, led-matrix-msgpack-rpc
- Update pd-audio-synthesis skill with Uno Q specifics
- Add Pd version check (min 0.54.0) to start-synth.sh
- Add DO NOT EDIT headers to generated pd patches
- Add Gitea Actions CI workflow for patch validation
- Add ConditionPathExists guards to legacy systemd services
- Add 'just ci' recipe for CI
Added notein→pack→noteout and ctlin→ctlout chains that forward all
incoming MIDI from the MPK Mini to the board's MIDI port. This means
physical keys/knobs now work alongside the GUI click buttons.
midi-bridge.py:
- Auto-detect rawmidi device (gadget f_midi > env override > fallback)
- Reconnect on ENODEV (device hotplug)
- No longer needs MIDI_BRIDGE_DEV env var in common cases
start-synth.sh:
- Remove all -alsamidi/-midiadddev flags (kernel lacks CONFIG_SND_SEQUENCER)
- MIDI handled entirely by midi-bridge.service → UDP → netreceive
- Host mode: same approach, no ALSA sequencer needed
mpk-mini-sim.pd:
- New MPK Mini Mk II simulator (25 keys, 8 pads, 8 CC knobs)
- Proper Pd #X obj format for all objects (bng, hsl, t, del, netsend, loadbang)
- UDP output to board:8081, matching midi-bridge format
system: enable usb-gadget-audio.service at boot, load dwc3 module at boot
