Hello, I have OpenMPT-1.17.02.54 that I plan to use to convert midi files to module files. I have created a midi file and I can play it with my windows media player. When I import this midi into modplug, the music sounds different from the way it sounds in the windows media player. This musical deformation will also be hearable after the music is exported as a module file(I can only export it as IT). I discovered that the midi file also sounds different when I play it in the quicktime player. So I guess each player has its own instruments for midi files. I like the music the best the way it's played in the media player, I need that music in some kind of module file. Is there a way to make the exported IT file sound exactly the same as the original midi file(played by my windows media player)?

MIDI has no intrinsic sounds, just instructions to play sounds. So it will sound different depending on which hardware or software is playing back those sounds - it might be the Microsoft software synthesizer, or it could be your sound card's onboard sounds.

Tracker formats like IT however use samples to play back their music. Typically this is done by embedding the instrument definitions in the tracker file. I seem to recall that MPT allows you to use a General MIDI sound bank, which probably results in similar output to that which you'd get via the Microsoft soft synthesizer route. However, I expect that you can't legally distribute those sounds with your file. So if you intend to distribute this IT file to others, it will sound different for each user (if it even plays at all - they may not have the GM sound bank that you're using on your PC). The alternative is to change the file to use different instruments that you're allowed to distribute.

If you instead used a compressed wave format such as MP3 or OGG, you could capture the exact sounds of your MIDI setup and distribute that however you liked. But then it would obviously not be in IT format. If IT format is absolutely necessary then you could write a new IT song, with a single note in it, that is playing back the compressed audio. This depends on the tracker decoding software supporting compressed audio formats, of course.

The reason I want my music to play as notes/samples is that my music should be treated as two parts:

1 the intro, that is played only once at the beginning

2 the main tune, that is looped

The sound from the last notes of the intro overlaps about a second with the sound of the first notes in the main tune.

I could try to make several wavs or mp3s and give each of them a time to start playing, to make it sound as if they were one song. However, then I wouldn't have that super precize synthesizer to let the right wav/mp3 be played at exactly the right (millisecond accurate) time. The time precision would depend on the framerate that my app runs with.

Or is it someway possible to link a wav/mp3 to a midi event?
Or to treat a complete wav/mp3 as a sample for IT?

If you're playing this under Windows, or any consoles then you can easily allow 2 streams at once - and specify the start the main loop to begin 1 sec before the end of the intro.

Is there a website that teaches this for C++ on windows?

There are many different ways of doing this in C++. But if you were going to use an IT file, what were you going to play that back with? If you had a library of playing back IT files then such libraries usually have capability for playing other sound formats, and setting loop points.

Originally the plan was using bassmod to play the music files. But now I hear it's possible to play a wav/mp3 with delay, that seems a much easier solution.
