Well then perhaps two instances of AUSampler.
Right, so I'm trying multiple instances of AUSampler, connected to a
MultiChannelMixer, connected to output unit, but I don't get any
sound, even with only a single sampler.
It does work on iOS though - both channels, where my audio graph looks
like this:

CurrentState:
mLastUpdateError=0, eventsToProcess=F, isRunning=T (1)
Just no sound output on OSX. I've tried to set the
kMultiChannelMixerParam_Volume to 1.0 and the
kMultiChannelMixerParam_Enable to 1.0 but neither of these made any
difference. Any ideas?
thanks,
Hamish
