I’m pretty sure I have written to the forum about this before; any case, here it is again. in my studio, I often start compositions using (gasp!) a guitar.
I record a phrase into an electrix repeater, & then start to build up other parts using the other tracks in the repeater to record more guitar, bass, keyboards, w.h.y.
then I will slave the sequencers to the repeater & begin on the step-sequence parts.
the sequencers are- P3, doepfer maq, notron, octopus. depending which one happens to best suit what I’m doing.
after I’ve figured the best tempo for the piece, I will lock it down & slave the repeater to one of the sequencers. the repeater’s own clock occasionally glitches.
