Browsing GitHub issues, I came across an interesting project. Oscmix.
Many audio interfaces have onboard DSP and mixing functionality. Even my MOTU 828 MK3, released in 2007, has a full suite of mixing effects, including EQ, compression, and reverb. As you might guess, accessing these features isn't exactly straightforward, and some technical know-how is required to unlock them. That's what Michel has been up to with the RME Fireface UCX II.
He has figured out how to access the onboard mixing, routing, and EQ.
But the coolest part is the user-friendly graphical interface he's created for it.
Even works over OSC
I would love something like this for my RME AIO pro, since that critter has all the DSP brains packed in it as well.
