I have a guitar track a bongo track and a vocal and I want to duck certain fundamental frequencies from the acoustic guitar when
a) the bongo is playing
b) when the vocal is playing
to do this, I set up one multiband compressor on the acoustic guitar track and send from the bongo but when I try and open up another instance of the compressor to send to it from the vocal, it doesn;t work. It is like I am only allowed one per channel. Is this the case?
