I do physical synths / drum machine as well, in fact I basically use a daw as a mixer with effects :) The latency is good, and I don’t have the newest machine or anything. On Linux it’s super easy to combine interfaces too, like I have my tr-8 (drums) as a multitrack USB interface, and an 8i6 for my synths, and it combines them way easier than I could do in windows! Take with a grain of salt as I’m an amateur, but for my purposes it’s been great so far.
Qwerty though? Remap that thing over to Colemak or something!
