Hello NI Community. I'm looking for information / guidance on if or how it's possible to utilize the Maschine+'s single physical stereo line-in ports to somehow control multiple physical devices' audio out signals, independently? I see that in the channel menu, you can select from inputs sources of either 4x stereo or 8x mono(L/R) but I'm not certain how I can assign sources to those channels with the single physical stereo input source on the Maschine+ hardware. I'd assume I will likely need an audio interface vs. just a standard analog mixer coming into the single stereo ports, but will the Maschine then just be able to know that the external sources are there and available and just work? I guess it's just not clear in my head how to assign sources to those variations of input sources? I've got multiple external hardware and would live to be able to treat up to that many devices as independent external audio sources all out of the box without the need for PC! I dug through the manual but didn't seem to see (unless I missed it) anything specifically talking about how to assign to the input sources. Currently I have to silence each device I'm not trying to record from to get an isolated signal, then do the same for each device until they're all either sampled or sequenced up, which works, but would be really nice to not have to do that if possible. Thanks for any and all help!
