I am able to hook up my rack and get sound with an 'External Instrument" in Ableton. But when I mute the external instrument track and press a key, I still hear sound (the sound is quieter though). Why is this? It's almost as if there are 2 signals going into Ableton. This makes the effects I put on the External rack almost non existent because there is a signal coming from somewhere that is unprocessed.
thanks!
