With the Luppp-1e182d3-x86_64.AppImage, it works but not properly. Sometimes, no tempo changes, sometimes the bpm taped is not set (tap tempo at 120 and Luppp set at 77 for example)

@sub26nico when playback is stopped?

With Luppp-ceec6d2-x86_64.AppImage, it doesn't work all. And the tap tempo during transport doesn't work properly (maybe my mouse?).
