Hi Dave,

I don't think that issue the firmware update addressed is relevant, as you're not transmitting MIDI to the UR22. Your MIDI signal is going to the Coyote WT, which sends audio to Band-in-a-Box's mixer, which routes that audio to your interface. Unless you're unchecking "Use VST/DXi Synth" and using the UR22's MIDI Output port to send MIDI to a hardware synth, it's not being used for MIDI at all.

Do you have stuttering when you use your internal soundcard on that same machine? If so, I'd say this likely has nothing to do with USB or the UR22.

Please try the UR22's MME driver, and also try using the internal soundcard with both MME and with ASIO (using ASIO4ALL). Let's see what happens in each case, that'll narrow things down.

Thanks
Kent
