I usually got some not-too-annoying latency with MIDI in Ubuntu, and Julian explained me a method to get much smaller lattency value.

Console command
sysctl -q dev.rtc.max-user-freq
returned 64 in my case. When I set 1024 frequency, latency was almost gone. So I first tested it with:

sudo sysctl -w dev.rtc.max-user-freq=1024

and restart ALSA with:

/etc/init.d/alsa-utils restart

In my case all MIDI applications (including TuxGuitar) worked much better.

To make this fix permanent you need to add line in file /etc/sysctl.conf :

dev.rtc.max-user-freq=1024



You have this process explained in Ubuntu help also:
