Start with a rhythm, not music theory
Choose a key and scale, then tap melodic steps. Even before you pick exact notes, the pattern has a rhythm you can hear and change.
Turn steps into a phrase
Move active steps up or down to change pitch within the selected scale. Resize a step from its edge with a pointer; on touch, press and hold, then drag sideways to shape its length.
Keep the idea fully editable
The pattern becomes MIDI in the active Song Part. Open its clip in Arrangement to refine notes, timing or scale, or ask Spider AI to develop the idea further.
