Midi and audio are not the same thing. With midi, you record the
"score" of the music (notes used, velocity, and timing). You can
playback a midi file of "fûr elise", and link it with a digital piano,
or a sampler that will play a trumpet. MIDI doesn't record any sound,
just the score.

If you want a real guitar sound, and not a synthesized or sampled one,
there is no use for midi.
To synchronize a midi track with an audio track, the only way, is to
edit the guitar track in the audio domain.

There are such software (i don't know for linux), but they do a very
poor job at it. And what would be the purpose ?
