APEX Mode

Assignable Parameter EXpression Mode

Keystone's core mission is to make music more expressive, creative, and fun.

To that end, APEX Mode quickly and easily maps parameters (knobs) to en external epression pedal. Hold down FS1 at powerup, turn a knob or many knobs to assign them to the expression pedal.

That's it... epression made simple!
