I am having some trouble here too. I have a TR-8S with 8 Audio outputs. I use Out 1 for the bassdrum, Out 2 for the snare etc...
I created a external Instrument in Studio One and set up the Aux-Channels. But when I Bounce my pattern, I somehow get a stereo mixdown?! I mean, what's the point of setting up multiple Aux Channels for one Device when you cannot bounce each one in mono to mess with the effects later?
I already tried creating instruments for each output and group them but the only way this works out is if I create a pattern for the Bassdrum, another one (on another channel) for the snare and so on.. so this is not what I want.
The whole point of the Instrument-Aux-Midi combination is to have the option to bounce your patterns directly, but this does not work with gear with multiple outputs.. or am I missing any settings here?
I hope anyone can help me or the devs can add the option to bounce each aux channel to its own track..
