I'm sure this question has been raised a few dozen times, but I skimmed over the search:feedback results without finding an appropriate answer.
I like feedback!
In a guitar amp, feedback is generated when the sound from the amplifier is picked up by the guitar's pickups and fed back through the amplifier, and so on.
How would it be possible to emulate this process in Max, with a dial (for example) representing the angle of guitar to amp? So 0 is no feedback (pickups are not receiving the signal from the amplifier), and 127 is maximum feedback (guitarist is fully facing amplifier.
Any suggestions are happily welcomed.
