The driver routes the output of all MIDI voices to the same accumulators.
You would have to rewrite that part of the driver.

Thanks Clemens. It appears I asked a similar question about 2 years ago, but I think it was forgotten about :-)
From what I remember, the assignments of the accumulators are 'organised' in emufx.c, so my guess would be to make the changes in there.
I'm unsure of how to refer to the outputs from the WaveTable synthesiser, as the current driver configuration only shows the stereo pair (e.g. master mix) coming from the synth.
I've come from the kX project drivers in Windows, where I know there's a two-stage process there too:
1. Use kXRouter to assign the synth outputs to FXBus channels
2. Use the kXDSP to connect the FXBus channels to audio inputs (e.g. ASIO)
So I would imagine with ALSA it's a case of compiling the routing into emufx.c, and then making the connections with lo10k1. Would that be correct?
Thanks for your help so far,
Dan
