Is there a way to get +1/-1 on the octave settings? There are lots of +9 and -9 which I can't imagine using but I just want to go up one and down one or down one and up two. Thanks.
Those numbers are just a mixer value for for + and – one octave (with 9 being the greatest), not the octaves themselves. Putting the knob at 12 o'clock will give you the full mix of an octave down and an octave up.
