[LAU] Syncing MIDI with accoustic guitar

All, Seems not that easy to use Ardour with seq24 in order to be able to add MIDI tracks to a recorded track of accoustic guitar (recorded using a seq24 4/4 sequence length 1 pattern that repeats itself). There's the lead-in 4 clicks during which silence is recorded in Ardour, that have to be chopped up afterwards so the accosutic guitar riff repeats itself to the click track seamlessly. Then the end of the guitar recording itslef that has to be adjusted to fit on the next click. The idea is to be able to have an accoustic guitar riff that repeats itself over a seq24 click pattern, endlessly. And during that time, being able to input new MIDI intruments of any sequence length. This is to try things out, not to have a setup that will be recorded as a final song. The final song though would be similar as it'd be synced to Ardour but would be based on the song editor of seq24 instead of simple patterns. It'd would be nice to be able to tell Ardour to start recording after the first pattern run, and then to stop recording after x number of pattern runs. Or maybe a seq24 song shoudl be used instead, right from the start. Any suggestions appreciated, thanks.
