JACK is pretty useful. You may be able to configure
/etc/asoundrc or $HOME/.asoundrc so that ALSA I/O is routed
to JACK[1].

Nama[2] is a command-line application that uses Ecasound for
recording and editing audio. Although it is currently
oriented toward audio, Nama can send commands to a midish
process, and has been used with midish and a2jmidi[3] for
combined audio/MIDI recording under JACK.

A simple hack for starting audio and MIDI in sync was to put
midish and ecasound commands in the same line:

nama> midish-command r; start # For midish, "r" means "record"

I expect we'll eventually add in a MidiTrack class that
would handle MIDI recording and playback.  For now, you
would have to issue all the midish commands yourself.
