i think (and i could be wrong) that you need a four channel external mixer to control the sound. However, you can control decks C+D with the VCI as far as play, loops, effects, etc. goes.
Yeah you’re gonna need 4 channels. You’ll need to upgrade to the Audio 8 DJ and a 4 channel mixer. Although if it’s possible, you could try routing decks A & B to output 1 & 2, and C & D also to 1 & 2. Then assign volume faders for your decks you are using with the VCI (so C & D for example). Might work, I dunno
i believe it can be done with a 2 channel mixer, u route the audio of the internal decks out the same channels as the external decks and then control the levels of the internal via midi.
i’m sorry i don’t know TSP well enough to know how to do it or if you still have vol control with the software mixer gone in external mode
You could route your audio through Ableton before routing it to your mixer, that would let you mix 2 decks internally inside of Ableton while routing the other 2 decks to the external mixer.
