It means you are organized enough to have a TODO list.

No Alsa MIDI app I've ever run has shown anything other 72:0 or 80:1. (qjackctl, kaconnect, aconnect, Rosegarden) Possibly Rosegarden now displays names entered by a user to describe these in text instead of numbers. I'm not even suggesting it should be automatic. If I have to configure something in .asoundrc or somewhere else by hand I'm fine with this. One other related frustration about Alsa MIDI is that under Gentoo at least my MidiSport is never recognized by Alsa until I hotplug it. This may not be true under the Planet flow. I could test that if necessary. The device is seen very early in the boot process, before Alsa is loaded, and the USB identification of the device doesn't change, but Alsa doesn't see it causing me to have to walk over to the unit and pull plugs before I can use it. > > 3) I have undocumented low-level 'concerns' about the timing accuracy of > > MIDI under Linux, but it's not so bad as to warrant 'worry' or a bug > > report.

(TODO: FAQ #15)) This is likely at least part of the problem. Is fixing/improving this done by changing the 'Timer Frequency' in the General Setup section of menuconfig, or is this some setting on the sound card itself? (Maybe handled during the alsa-driver build?) This answer confuses me. Do I need to do something with both 'timers' AND 'the RTC to make Alsa work better?
