Pedal test: waiting for MIDI

Pressing a pedal (value ≥ 64) starts or stops the band once. Releasing does nothing. Pedal control requires incoming MIDI messages.

PIANO · ECHO ROUTING

MIDI CHANNEL PLAN

Piano 1 · Drums 10
Bass 2 · Chords 3 · Extra 4

Connected setup sends Local Off and echoes your keys to GM piano 1. Sustain follows the piano. Band Stop leaves your piano playable.

Left piano: off mutes keys at or below the split, while those keys keep controlling the band. Local Control commands are sent, not confirmed by the piano.

Pan uses standard MIDI CC10. Stereo placement depends on your piano and speakers.

GETTING STARTED

Play with the band

1 · Connect & play

Connect USB MIDI in Settings. Play chords below the split point. The chord display follows your left hand; your right hand stays free.

Major, minor, 7, maj7, m7, dim, aug, sus2 and sus4 are recognised.

2 · Lead the band

Choose from the sixteen supplied styles. A–D subtly lift touch and dynamics while the source pattern stays steady; Human Feel shapes touch and timing. Intro, break and ending follow the bar. Fills are removed for a steady groove.

Left CC67 starts, middle CC66 stops. Right CC64 remains sustain. Release does not trigger an action.

3 · Shape your sound

Use the four upright faders in Play. Each has volume, mute and a left/right pan control. Double-click Pan to centre it.

Musicians appear only in Play and respond to their MIDI notes. Other tabs keep the controls and style names clear. Muted players rest. Shade darkens the wood; both finish and shade are saved.

4 · Install & update

Version 0.9: sixteen supplied pattern styles. Low-key changes are briefly grouped and applied together on the MIDI grid, without restarting the drums. Shared notes can continue through chord changes. Celtic Folk uses 6/8; its BPM counts dotted quarters. Old SongBook styles are labelled when mapped to the new set. Local Off / Echo On and Restore normal piano are unchanged.
