I’m not a professional music producer, I am still learning.
I am running my music production in a MacBook Pro with OSX El Capitan, and I have set up system audio to have Quadraphonic speakers. But FireBox has its own FireBox Mixer which seems to give only two channel outputs at once (by the way, I have never heard any sound from any other output than Main 1-2), not even in the “speakers test” for channels 3-4 at Audio MIDI Setup (see screenshot attached). Should I uninstall Persons FireBox Mixer?
How can I get Quadraphonic output with FireBox?
