All roland gear I know runs from 5 V and isn't the Roland x0x serie defining sync itself ? :-) > some sort of semiconductor switch so a "note on" means run, and the next > "note on" will flip the flip flop back to stop it.

I am working on that. GEt a circuit that stays on if the input gate is on, but shortly brakes this state to go down to 0V shortly and rise back in kind of a inverted triggering way. This will cause a 202 e.g. to start up again. Now get this effect started by a usual trigger (like the 909 rim etc) and you cen get any sequence of any lenght looked to a running system. I have no idea though, how to get this inverted triggering. I'll work on that and let you know. stefan > -- * real electronic composers don't like their music be restricted * * to the physical limitations of the human hand - AH - a great list * * Stefan Gruhl * xxxxxxx@xxx.xxxxxxxxxx.xxx-xxxxxxxx.xx * * Monthly bonus sig: ************************************************ * "The course of true SOUND never did run smooth" * * freely taken from Midsummernights dream by Willy S. * ********************************************************************* *
