Notes prepared ahead keep playing on time even if the phone stalls. Knob changes are heard after this delay.

Each composer's strip in the deck shows the parts they play (Melody, Chords, Bass, Rhythm) with the instrument for each. Tap a composer's strip to open it, then tap a part to switch it on or off and pick its instrument.

Blend style

Over MIDI, the ensemble's sounds are sent as General MIDI program changes, which GM synths follow. In Logic, pick the instruments on each track instead.

Composers, breeding, tempo, key, dynamics, sounds and the melody and accompaniment switches change the music live. Length, form, mode, meter and key changes are planned when you press Play.

MIDI control

Turn knobs and faders on a MIDI controller to move these sliders while the music plays. The standard layout uses the mod wheel for Dynamics, CC 7 for Volume, and CC 21 to 29, the first knob bank on many controllers, for the rest. Press Learn and move a knob to assign your own.
