What are you trying to do? Don't forget that signals are essentially floating point numbers streaming through at the sampling rate, so when you say "sends alternatively zeros and ones:, you'll need to specify how frequently you want them to switch. The help file for >~ shows you how to make a signal that alternates between 0 and 1. You could also look at the train~ object which goes from 0 and 1 as well. Here's an example of what I think you are looking for:

Maybe thresh~ is what you need

Thanks guys for your help. I have an incoming signal that is constantly at 0 except for very short peaks at 1 (coming from the metronome samm~ by Eric Lyon). I want to send 1 in signal to a sfplay~ the first time there is a peak from the metronome, and send it a zero the second time, and so on. I ended up doing this with edge~, toggle and sig~

but I wonder if leaving the signal domain for a short time with edge~ and coming back with sig~ keeps the sample accurate precision of the sfplay~

Try this:

Oh thanks!!!

Or this:

Above toggle~ in GEN (the simplest way I can think about atm). if [+=~] -> [%~] accumulates too much it would stop working (with 64bit floats it would take some time, but nevertheless...).

Thanks a lot this is very helpful!
