Shrinking Notes Bug

Hey Fingers here is that project file and the script.

There are events on CC3.., I tried with a couple other CC's and received the same result. Just run the script and you should notice that some notes shrink to zero length. As I stated in my post at the REAPER forum this only happens when CC events are present.

Thank you,

Anton

A little more info;

I noticed that the bug does'nt appear if you run the script on an item with only one row of notes and I think it even ran fine with three rows of notes.., Oh-yea this is running on Windows Vista.

i can fully reproduce that with a brand new midi item and with just
allocating and freeing a midi take.

Some note-on's get shifted towards some note-off's of the same pitch, so they will instantly set off. I attached the relevant part of the chunk of Anton's project item.

some interesting points i found out:

• it dont need to be note rows to be buggy
• it only happens after drawing a specific number of adjacent notes and when at least one cc is in it

Thanks mths.funk for looking into it. I fixed it in r923 and r924 . I just changed the sorting function to order by note offset, followed by event type with a special case for note ons.

The issue is that the note-off and note-ons for the same pitch and channel were being switched, so the note-off message for the current note was being put after the note-on message.
