Operators

AND

The AND operator creates sudden jumps with the read position. It works by clearing

selected bits in the read position data word. Turn on SYNC and flip the higher

(left-

most)

bits to create beat-repeating effects. The middle bits generate granular "buffer

underrun" effects while the lowest bits can be flipped to achieve "aliasing" like from a

bit-crusher effect.

MUL

MUL changes the rate of the read position in relation to the write position. In other
words it will change the pitch and / or speed of the input audio. The operand is a lin-

ear rate multiplier

(expressed in fixed-point notation with sign bit)

Some examples:

0200 = double rate (1 octave up)
0100 = normal rate (no change)
0080 = half rate (1 octave down)
0000 = stop
8100 = reverse (leftmost switch flips the sign to reverse mode).

(Unlike a proper pitch shifter, there is no crossfading in

Permut8

which means there

will be audible clicks as the read position and write positions meet.)

OSC

OSC makes the read position swing backwards and forwards in a triangular motion.

The results range from wobbly backward / forwards effects to subtle pitch vibrato to
