so, ideally this patch would be able to play an audio file and have me change the temperament in real time.

That is a tall order, I understand. I am new to this and don't have much time.

If I could take midi input and change the temperament, I would be very very pleased. I don't need to modify it in real time, but that would be a plus.

Is there a patch or an object that I should begin with? Is there a simple way?

Thanks!
