Hi! semi-n00b here. I'm working on a modular-synth-style virtual synth in pd. I'm using arduino to make a physical interface, similar to those on old modular analogue synths.

I would like to have a decent way to patch output from, say an oscillator, through a series of pd effects. However I want to be able to change the order of the effects in the sequence between the oscillator and dac~ on the fly. To make it more complicated, I intend to do this only with my arduino interface, no gui at all.

Is there any good strategy for patching effect modules together without either a gui or physical patch cables? Maybe something like a radio item that sends signals in numerical order?

Thanks for any advice, sorry if this is unclear!
