Just like with the MIDI channel configuration, you need to set up your device mappings (this time with audio outputs), like in this image:
You can either enable the audio outputs on your existing MIDI input mappings (so you can have MIDI input and the corresponding audio output on one track), or create a new mapping for each output (keeping MIDI in and audio out tracks separate).
Just make sure you select the right configuration – Hypersonic’s outputs are probably stereo pairs, so it’s channels 1+2 for output 1, and so on!
It’s also probably best if you save this in your Podium plugin database, or create a project template when you’re done, so you won’t have to do this in every project.
Let me know if you need any more help!
