If you use Linux to edit audio, mix songs and work with audio in general, including having trouble making certain audio hardware work, it’s your chance to join a community effort to make Linux audio creation better and more accesible.
The Audio Creation SIG (Special Interest Group) is a hub for creators to help each other create and together try and find ways to get better hardware and VST support for Linux.
As far as exotic stuff goes, I only buy stuff that’s class-compliant so I don’t have to worry about the manufacturer sunsetting support in the future. Supporting those sorts of devices should be a priority over anything with weird proprietary issues (fuck you IK Multimedia!).
