I just tried 2.1 version and currently I found 2 bugs.
1. The light doesn't appear on every note for fast passage. I'm not sure if its related to the fps setting. Here is the video which have this problem, not quite obvious but noticible if you pay attention to it.

2. When i render the video, the last notes still seem to get cut off. For this song, when i render it the video is finished before the particle disappear. So the last frame stopped while the particle is still there. I have to create a longer midi with some extra notes after that to avoid it. Not a big issue but i think it's probably still related to the play speed in the app which caused that?
Thank you
These bugs should now all be fixed in Beta Version 3.2. Thanks for pointing them out!
1. For the fast notes, they likely are showing, but just for 1 frame (I've worked many hours to make sure that notes show at least 1 frame). This is related to FPS and extreme short note length - if a MIDI note lasts for less than the duration of a frame, it becomes very difficult to manually override that and make sure that it shows up in the video. I'll take another look, but the best solution would be to set a minimum note length for the notes in your MIDI file using your MIDI editor (Logic / Cubase, etc.).
2. I'll check this again - I thought I had added enough padding at the end of tracks to make sure this doesn't happen, but maybe not.
