I'm interested in working on writing a piece (for live performance) using simultaneous independent click tracks, in order to easily create complex rhythmic relationships. For instance, having four performers: 1st receives click of 60bpm; 2nd receives 65bpm; 3rd receives 70bpm; 4th receives 75bpm.
How could I do this?
Obviously this is easy with just two clicks, as you can use a stereo output. Also, it would be easy to simply send each performer a completely independent click at their tempo - but this defeats the object of creating complex rhythmic relationships; the clicks need to periodically align.
It would be good to get an answer with the simplest possible setup, e.g. Laptop + Software + Interface/Mixer ( + Mixer) + Headphones. In other words, something relatively easy to set up, not needing loads of studio gear. Also, would be good if this is easily scalable, to use a higher number of independent clicks.
Although I'm a guitarist - assume I know very little about Music Tech…!
EDIT: would be good to have a solution that allows me to generate clicks of arbitrary tempi, rather than simply creating a pre-recorded multitrack recording.
