Won't start. I can do right-clicks though and it opens dropdowns:

It looks like you haven't started JACK before starting Luppp. Try starting the JACK daemon beforehand, e.g. using QJackCtl.

[sezanzeb]

not having started jack gives me different errors:

however, it works today, so I cannot reproduce the issue anymore.

The error logs you posted indeed seems like Jack2 (the version of JACK you're using) is having some issues with something... not sure exactly what.

@sezanzeb - to confirm - Luppp is working OK now?

[sezanzeb]

it launches yes, thanks.

I was hoping it would work differently though, or maybe I just didn't figure it out yet.

The nux loop core, once it has the loop length set, will start recording over the beginning once it reaches the end.

for example, playing like: --o--o-- over 4 beats would result in -oo- being recorded. And it will also play back --o- while recording -o--. Like a tape that continues to go in a circle, and new incoming sound adds to the existing sound, while the old existing sound is played back.

I would love to reproduce this on a computer with multiple tracks.

Luppp has "overdub" behaviour, as well as recording. I'm not following the exact description, but the "UI won't load" issue seems fixed at this point, closing.
