Hi friends.. I'm in need of a quick solution. I'm trying to change the tempo of MIDI music programmatically . The idea is to queue up all the midi notes from a fast playing input midi node and then rate limit them to slow them down. I'm trying to use the 'rate limit' option in the delay node.. but that only goes down to 1 message per second. I need to be able to go down into the milliseconds. Is there a a way to rate limit down into the milliseconds. For extra credit .. i'd like to control the rate programmatically like from a slider.. any ideas ?
while i'm at it .. does anyone have an example of generating polyphonic Midi from Node-red using node-red-contrib midi ? .. I see the opcode is supported.. but cant figure out how to make that work..
