Okay, a few little things:
1. The preferences is not working as it should. Clicking, for example, on <groove dir> brings up a short list of directories, but I cannot step though a selected dir. I'm only able to select a top level entry.
2. I can edit the .linuxband/linuxband.rc file and change the paths there.
3. I think there is a concept problem with swingmode. You're not the first to have this problem ... but the way you are using it (just like in lemma) it has no effect. The loading of a groove restores the previous setting. Doing it after a groove is loaded doesn't help either since the sequences are already parsed. For a user, the only time swingmode has an effect is when you have something like: Swingmode On ... some solo notes .... I think this is covered in the docs, but I'll re-read them before the next release.
4. Not sure how you are doing the "follow the bouncing ball" thing to highlight the chord changes. But, I might be able to help at this end by writing data to follow into the meta track of the midi.
5. With jack running I get no sounds playing a midi track. Player issue? Jack not setup right? I don't know since I normally don't run jack.
...........
If I send more time on this I'm sure I can help more.
It's a great concept and should help folk who, unlike me, don't love the command line
Look forward to the next version!
Best,
