Not sure what you mean by "polyrhythmic". There are two basic approaches, and which you want will determine which modules you will need (besides the VCO / EG / VCA chain for each voice).Auxiliaryoctopus wrote:My goal is to set up polyrhythmic sequences with two separate oscillators. I want these sequences to be melodic. I want to be able to choose the specific notes of each sequence. What would I need to be able to do this, (aside from the synth voices themselves)? Would just one Yarns be able to do this? Would I need two?
Approach 1 - different rhythms, same basic tempo. Pamela's Workout works fine for this, using the various programmable aspects of each clock, you can do swing rhythms, hi-hats vs. kicks, etc. etc. Random is possible using the "skip" feature, and the alternate Euclidean sequencer firmware can provide some very interesting beat configurations. But all variations are just divisions/multiplications of the same base tempo (Pam has tempos ranging from 25 to 300 BPM).
Approach 2 - different rhythms, different tempos. For this you need two clock sources, distinct from each other. In the simplest case, you could use two LFOs for this. But the rhythmic aspect is lacking, so you need some kind of rhythmic clock source for polyrhythms. Like 2 Pams Or you could use AND logic with a S&H module and an LFO to have only certain pulses transmit (this gives essentially random rhythms).
I second the recommendation of a Z8000 - it will work well in this application, regardless of approach. But you could also use two smaller (cheaper) sequencers if you want the melodies to be independent. I like the XAOC Tirana for this kind of application, as you can easily remove steps from the sequence for rhythmic variation.
