Getting stereo precue and output with a regular 'ol mixer.

Thanks for the great suggestions @PKtheDJ and @Michael_Wisniewski. There are also some great suggestions for proper USB sound cards/audio interfaces in the topic linked below. You might also want to check out the Reloop Flux (https://www.reloop.com/reloop-flux), although it sounds like this is probably larger than what you’re looking for. Personally, if it was me, I’d go for something like the Reloop Mixtour so you have some physical mixing controls, but still in a small form factor. If you can wait a bit, it sounds like the upcoming Mixtour Pro will have a higher quality sound card than the previous iteration.
