Hi,
I am trying to control a multi-channel USB sound card in PsychoPy in order to create stimuli on any of the sound card’s channels. I need precise timing, so PTB seems the way to go. However, I don’t see any possibility to select the output channel in the PsychoPy function.
In the Psychtoolbox under Matlab/Octave it is possible:

In python it is also works using a library provided by Syntacts:
Here, it is possible to create any type of stimulus on any channel. But the timing is not sufficient for my application (as it does not use anything like prescheduling as the PTB driver does).
Is there any update planned that the multi-channel functionality will be implemented in the PTB sound in psychopy?
Grateful for any hints!
