Summary0001195: MIDI export sometimes assigns instruments to wrong channels and/or detunes at random
Description

When selecting the option to allow instruments to overlap channels, sometimes this causes instruments that are playing to be overwritten by other instruments that come in later in the song. When the overlap option is disabled however, the MIDI will go off-key during random sections. This means that no matter what is done, I cannot achieve an accurate MIDI export.

Steps To Reproduce

This seems to occur primarily with files with instruments that come in later in the song; songs that use the same instrument set from beginning to end do not seem to have this issue. Does not seem to affect percussion instruments.

Additional Information

I would enclose a source file and the MIDI exports with the issue but the uploader does not seem to support these file types.

The "overlap" mode behaves as intended, by the way. It is intended to be used when exporting stems that are then used as individual MIDI tracks in the DAW where they are imported. The rationale is to be able to export more than 16 concurrently playing instruments for this usage mode.

The default mode, however, should behave as most people would imagine and as if all instruments were exported into a single MIDI track. I have now managed to reproduce your issue with the pitch bend based on the description, so there is no more need to upload an example file (you can simply zip or 7z your modules to attach them, by the way).
