<div>Hooking up this MTPAV has been frustrating enough that it looks like I'll be needing a USB MIDI box too (e.g. <a href="http://github.com/koppi/alsa-midi-latency-test/blob/master/benchmarks/um2ex.txt">http://github.com/koppi/alsa-midi-latency-test/blob/master/benchmarks/um2ex.txt</a> or <a href="http://github.com/koppi/alsa-midi-latency-test/blob/master/benchmarks/midisport2x2ann.txt">http://github.com/koppi/alsa-midi-latency-test/blob/master/benchmarks/midisport2x2ann.txt</a> )</div>
