Ah,  now that you've explained how it works, I do recall hearing pitch
changes that were probably due to the modulation - it sounded great!

The PCM-42 delay line has an LFO which is used to modulate the delay 
line, it can be used to create flange, chorus or wobbly echos. It has 
two waveforms available, triangle and square. If you use an expanded 
memory PCM-42 and modulate your loop with the square wave the effect 
will be similar to having someone switch the speed of a tape machine, 
with dramatic jumps in pitch and speed.
