This is a fantasy project,
The synth is a Yamaha CS-5, although if i got it working i'd also try it on my fender rhodes which also has a blinking LED.
The light turns off and on to show the rate of the LFO.
Can i set up a light sensor or camera and a Max patch that measures the rate and either outputs a number in BPM or drives an LFO that matches the LFO in the synth?
any thoughts? x
