Well, this is a well-known limitation; Module formats and MIDI don't have very much in common so the conversion can never be exact. The MIDI import code will probably be rewritten and improved at some point, but don't ask me when that will be.

Thank you for your attention. I would really wait for further developments.

I have to agree with him here. MIDI import's been a problem with the tracker ever since I've used it.
I think you could make 'Note Delay' more fine and possibly add a 'Note Boost' or something that allows notes to jump in ahead of time also.
I think that would do it, at least for the timing issue--which seems to be the most serious issue by far.

The timing issue cannot / should not be resolved by note delays; the problem at hand is a completely different one, described in the thread that also gives you a tool to fix your MIDI files to be imported more nicely into OpenMPT: https://forum.openmpt.org/index.php?topic=4703.0

r6840 introduces the long-awaited fixes for MIDI import. It will be up at https://buildbot.openmpt.org/builds/ within the next few hours, so please try it and see if you can spot any MIDI files that still sound very broken.

Wow. Finally, the long awaited features is come.
Thank you very much for the fix, Saga. It makes me almost cry when know about this.

Just a little more request before you release the 1.27 version.
Please translate the CC#111 event in MIDI file as a loop point in the resulting module. The CC#111 event is not a standard way for MIDI loop, because unlike module, there is no such thing as loop point in MIDI, but it seems a standard way for looping MIDI in some Japanese software, especially RPG Maker game engine. The other software known to support CC#111 MIDI loop are Sekaiju, Foobar2000, and smfplayer.js.

I understand that we can manually add loop point later after conversion, but it can save huge time if it can be done automatically, especially if we have large collection of looped MIDI that needs to be converted to module file.

For reference I attached a sample of looped MIDI file (try Sekaiju to play its loop point). This MIDI file has CC# 111 event and will play from beginning for the first time, but will loop to the loop point after it reach the end, without starting again from the beginning, therefore the game music can be played infinitely.

Best regards,
RyanBram

I know about CC#111 but I did so far not implement it because it would conflict with e.g. how Doom supposedly used the CC. I will think about it though.

Implemented in r6892.
