trigger seq / polyrhythms

speaking of trig seq's...(florian's ideas look great, btw) there's something i've been trying to work out how to do lately and i wonder if any existing sequencers or groups of modules are capable of doing it. say, for a trig seq w 2 or more rows.. can one row be, for lack of a better word, 'slaved' to another so the loop cycle time of each row is the same length despite each row having different numbers of steps? i guess one way to do it would be to have a seq that derives its step tempo by CYCLING once per trigger rather than STEPPING once per trigger. so to get your beat divisions each row would need a simple clock divider to determine step duration within that cycle, and ideally could be automatically calculated by the # of steps in that row which are 'on', or by the # of steps between the first/last 'on' trigger for that row. that way you could have syncopated 1/2 note triplets under a 4beat and even rest on the 2 of the triplet row. (this 3 against 2 example can actually be done already on a single a155 using 2 rows w 6 steps each, accenting the 1&4 on one row and the 1, 3, 5 on the other, but anything requiring more complicated subdivisions is impossible). i think this would be a great 'mode' for a trig seq if nothing else. also, now that i think about it, i guess what i'm really wishing for is a clock divider that can deal with divisions beyond the straight 2, 4, 8, 16, etc. if regelwerk or schaltwerk can do this, i want one! rhythmically challenged, duff
