I've been tinkering around with using clock sync'ed lfo's for making rhythms and I could use some tips from you all on using them, especially keeping them in sync when the rate is changed. Also, I need a method of offsetting an lfo if I wanted to start it on the up beat rather than the down beat, for example for a standard kick/snare combination. Also, is this idea more crazy than it's worth? Will I just end up eating more DSP power than just working with lots of sequencers?

One idea is to use a ShapeLFO with Direction set to zero, so it doesn't oscillate anymore, but rather acts as a waveshaper. A second LFO, which is clock-synced and set to sawtooth, will act as a driver for this waveshaper. By multiplying this driver LFO by 2,3 or 4 and connecting the results to a 4-1 switch, you can drive the waveshaper (modulate its phase) at 4 instantaneously selectable speeds, but without ever losing sync with the MIDI clock when switching around. Also, the Phase control knob of the ShapeLFO neatly serves as an offset in your intended fashion.

I used this approach some time back with my DeluxeLooper patches.

Example attached.

cheers,
