Fugue Buddy echos whatever you play, transposed and delayed. Use it to help you write classical fugues. You know you’ve been itching to write classical fugues. Actually there’s a lot more going on in a fugue than what you get here. Maybe I should call this “Strict Canon Buddy.” This was ported over from the Organelle version, but the Pocket Piano version allows you to record your sequences and is better in other ways.

Tempo Knob sets click tempo, as it usually does.

Knob 1 sets transposition interval:
all the way left = down a perfect fourth
12 o’clock = unison (good for playing rounds)
all the way right = up a perfect fourth

Knob 2 sets octave of second part

Knob 3 sets number of beats of delay (1-16)
