FWIW I had forgotten how good the Zoom B2.1u works as a USB interface. My usual suspects including a B3 and Fast track were already in use with other computers and needed to do a quick turnaround on a couple of songs today on a laptop a friend dropped by, I hate to jinx a work in progress by moving hardware [curse of being a luddite]. The B2.1u was plug and play and ran like a dream, phat juicy bass trax recorded in no time flat. And yes of course we followed proper social distancing.
