converting stereo - mono on the fly

    Aug 20 2010 | 2:35 am
    Hi guys, ive been looking for a piece of software for a while now which can convert stereo sound into mono, effectively doubling a sound card output on a mixer.
    i currently use dj software traktor pro, which allows 4 decks to be played simultaneously all at stereo sound (meaning 8 outputs needed) however my mixer only supports 6. is there a way i can technically 'marry' one of them up meaning 1 deck can come through L output and another deck play though R as mono sound eg (2/1 - 2/1)? i hope this makes sense.
    thanks in advance, Simon
    edit: hopefully this diagram will explain things better -

      this is not really max stuff, but can't you assign, say, deck 3 and 4 to output 5-6 and hard pan them left and right so that you get deck 3 through output 5 and deck 4 through output 6? if traktor won't let you to pan, you can probably use rewire to route sound to max or logic to do the assigning.

      Max should let you bring in all 8 channels via adc~, then you can route however you want (including wacky configurations on the fly using matrix~) out to your dac~. If your sound card is recognized, you would use dac~ 1 2 3 4 5 6 and route the appropriate signal cords to the respective outlets.
      If you haven't used Max before, try out the 30-day demo and read up in general a bit, then look at the help patches for dac~, adc~, matrix~, and probably [preset] where you can easily store different configurations for your routing (the matrixctrl UI element hooked up to matrix~ which does the actual signal routing).

      In Traktor, if you only assign the left channel of a deck to an output of your sound card, the program switches to mono by itself (this is in the manual). No need for extra software, let alone Max/MSP.
