Dave,

thanks. As far as hardware midi is concerned, I'm OK, but I was
wondering about soft midi, say from Timidity. Does alsa provide
soft midi connections by default (the 'virMIDI' ones?), or do you
have to configure them?

Also, I am using -+rtmidi=alsa (no portmidi in the system I want
to do this, the OLPC). If I list with aconnect -l I generally get
just the hardware ports. How to get the soft ones?

Thanks

Victor
