We have recently purchased a Studio 1824, and are having trouble connecting a multichannel speaker system to Reaper DAW (also tested with SuperCollider).
When the DAW sends to hardware outputs 1 through 4, the sound does not go to the designated output speaker, but instead some arbitrary mix of them (almost always channel 4 and one other channel, never 3, and so on). Is there a way for us to see the I/O matrix mapping for the interface? The universal control does not seem to give enough usability with this regard.
The speakers were connected to line outs 1-4. When we connected each speaker to out 1, they all worked, so the problem is not in the rest of the setup. We hope to use all 8 outs and maybe also the monitor stereo pair to send to speakers in an installation.
The opening of the installation is tomorrow, so your timely help is appreciated.
