Hi, I've been trying to get the rotary knobs to control the dsp tremolo effect speed and depth for a pcm tone. I have read the manual many times. Especially parts where these settings are mentioned. No luck. There is a long list of parameters to select for the knobs but none of them seem to control dsp effects. I've tried most of the likely settings. Has anyone done this? You would think it's possible and I just can't figure out how to do it Thanks, Pete
