STEREO PITCH SHIFT EFFECTS

If you selected PITCH SHIFT in the field, the screen will look like this:

The pitch shifter allows you to set an interval for left and right. More often than not, a

small amount of detune is set here (i.e. LEFT = -00.05/RIGHT = +00.05) but you can also

set these parameters to specific intervals such as a fifth (+07.00) or an octave (+12.00) or

whatever.

NOTE: As with all but the most expensive pitch shifters, there is a small delay in the pitch

shifted sound. This can be used to enhance an ensemble effect, however. Also, extreme

pitch shifts will exhibit some ‘wobbly’ artefacts. In this case, mix the level of the pitch

shifted signal back a bit.

If you select PITCH SHIFT+FBK (pitch shift plus feedback) in the page, you will

see this screen.

This is exactly the same as before and you may set the pitch shift interval as described

above. However, in the PITCH SHIFT+FB selection, you also have access to a delay line.

The delay parameters allow you to set a delay time for the feedback loop. This effects

selection looks like this as a block diagram:

SHIFT LEFT

SHIFT RIGHT

The signal from the pitch shifter is fed back into itself via a delay time. If you can imagine

it - the sound goes through the pitch shifter and, after a delay, that pitch shifted sound is

fed back into the pitch shifter where it is further pitch shifted. After a delay, it is fed back

again after the delay and shifted again. The amount of feedback and the delay time for

each channel is separately variable and this gives rise to all sorts of weird and wonderful

arpeggio effects.
