I have this nice rhythmic setting on the band delay, whith tempo on (delay A to 1/4, delay B to dotted 1/8). I would like to slightly decrease the overall delay time, but just a little. If I use the knobs and try to set the delay time A and B to the next lower value, it's just too much, I would like it somewhere in between. I tried setting the tempo off, and working in milliseconds, but the delay lines are no longer rhythmically related. Can anyone help me?
