I'll start:
1) mode 1 > mix to 1 o'clock or so > quantize set to free > set pitch to just below unison > apply a max speed, minimum depth lfo > set feedback to ~ 3 o'clock > adjust len b to fastest, then dial it back till you get a real nice underwater sound.
2) classic mode 2 > mix to taste > quantize to 5ths and octaves > set for 1 octave up/down/backwards to taste > Len s to very short, but find a rhythm > set random to taste (on the low side, but depends on your input) > hold soft button for a second or less > play live into the pedal while holding soft button down with occasional strategic lifting of the button for tasty freezes / glitched up goodness. Sounds really good w/ max reverb going into the ct5, (would love a 2nd verb after it
)...
I have more, but that'll do for now. I wanna hear yours.
What's your favourite settings? I wonder if you have found a trick which I have not...
