It appears my first hunch was right. I swapped the EPROM after playing
with it a bit. Put in the old version 1.0 I had in my tray. The lfo
works great with that in there...
My friend on the phone said that I could easily get signed on a label
doing 'glitch' music with some of the stuff I was doing with it! LOL. I
was modulating a sound with that weird half wave lfo half wave garble.
and arpeggiating and varying the lfo rate and some filter settings while
playing chords on it.
