i'm building a midi controller for ableton live called sifão,
i've included a exterior sound car for line in and line out.
since i don't have a fancy sound card, i got a crappy usb type pen just enough to get something in and out
now the problem "how to connect two sound cards", the internal and this pen type crap
i use the asio4all driver that allows to connect multiple sound cards and you can assign what you want each one "ear", unfortunately i didn't found a way to send the same thing trough 2 outputs...
digging in ableton live i've found that you can set one output in master for two channels 1/2 (left and right) and you can assign individual tracks to another two channels 3/4 (left and right - the external sound card) but again, it doesn't allow to send the master to 1/2 and 3/4 at the same time.
so i've created a audio track and in the input routed to the master and the output to the 3/4, so the master will go to 1/2 and the audio track will go to 3/4, just as simple as that.
since we are talking about crappy material, there is a slightly latency between the two outputs but is nothing big...
does anyone have a better way to have the same thing going out to 2 sound cards? help appreciated...
thanks
