Hello,

I am programming generative music and I was wondering about different ways of syncing multiple instruments together. Which one is more accurate?: creating a patch with one metro object, and sending the signal to each instrument to process, or to have each instrument have a metro object of its own, and starting them simultaneously?

I have experienced trouble with a main metro object sending signal to each instrument.. it seems like when the signal is going into several layers of subpatches, some delay occurs which depends on the number of subpatches, the objects it goes through etc.. Whereas two metro objects started with the same BANG in different subpatches provide no extra delay.

Could you possibly post a patch that illustrates this? As a rule, for perfect sync there should be one clock to rule them all. It seems strange that multiple [metro]s would have better timing than a single, master one.

when you say that you have layers of subpatches, do those include throw~/catch~ or send~/receive~ pairs?

in those situations, you'd often get blocklength delays in your audio signal. You can have a look at audio help G.05_execution_order if that's the case.

Thank you for your answers. I will make an example patch asap. I am debugging my code atm, and it seems like one master clock is the way to go.

@mod: I don't use any of those, just plain wiring.
