frequency()

Schedule a frequency on the device to play after a delay and last a set time.

midiout.frequency(frequency, start, duration)

Play only one frequency per channel at a time: since this uses pitch bend, it affects every other note sounding on the channel.

Parameters

midiout.frequency(frequency, start, duration, dynamic=100, channel=0, panning=-1)
