untouched, as you say. -+rtmidi=alsa, however, doesn't seem to give MIDI 
control.

You are completely right that MIDI input is done via USB for the most part 
these days (including on the XO-1). So it should already be included in 
Sugar. I assume this means, as you say, that it is emulated in software - 
but I don't know.

In any case, ALSA MIDI is crucial to realtime Csound, and I fervently hope 
we can get it going, as with the XO-1. I'll as always be more than happy to 
do *any* sort of testing, and am well positioned to do so. (You want any 
particular MIDI device? You name it; I've probably got one.)

Thanks so much for all your monumental work
