Scales for the 4-Voice Polysynth

Pick a root — melody lines that never wake the voice reducer.

The 4-Voice Polysynth scale reference: choose a root and one of 24 types — common, pentatonic, blues, modal, bebop, symmetric, world — and see the pattern lit on the keys themselves, 4 voices across its 49 keys (C2–C6).

The 4-Voice Polysynth answers touch, so practice these maps at more than one dynamic — the pattern is the same, but the hand that plays it soft and loud owns it twice.
