Thanks Lanefair,
I know the X knob function and the stereo waveform settings but as already mentioned delay A has always a deeper modulation than delay B and delay B doesn't modulate at all with a 0ms setting no matter which waveform I choose while delay A always does…
I think user documentation about how algorithms actually work in lower end effect units has always been very poor to be fair.
I hope eventide will improve that in the near future!
