MSX Musics > MIDI

Lazy, may be.. but as J-War points out: it's about spare time. If the MIDI route is faster, then why go slower? For one tune it may not make much of a difference, but for a whole game it may.. especially if the game is the size of, say, Xak, MG2, SD-sn., IC etc.

Reverse operation is possible, making MID files into files that can play MSX with OPLL or SCC?

Thank to Quibus to mention this post.
However, it's not very hard to convert PSG or SCC to audible frequencies and then it's just matter of maths and you have the correct note (note number). Later, it's even easier to convert this number to a note name like C#.

On KSS-X I decided not to spend time on the .mid file format as there is too many information to provide as well as I do not have time to learn this format.
Instead, I send the note to the default IAC driver which then can be access from any application.
For testing purpose I use Garage Band with it's very limited features (For instance it's unable to distinguis midi channel, putting all notes on the same track).
At the moment, if I want separate channel for each Msx channel I need to do multiple recording.
The code is not finished and I still need to do fine tuning to make sure the score is human readable while containing a maximum of information.

As is, I tried with Dragon Slayer 6, Town PSG version as well as with Yaksa.
The result is there :

The bass do not play enough note (all repetition are lost). But it's going to be resolved soon.

One of the various test of Dragon Slayer 6 Town leads to this:

or this:

Here is the code to convert the audible frequencies to note number.

if(frequence>=16)
{
resultat[0] = 0;
result = log(frequence)/loga - r3;
resultat[0] = round(result);

return resultat[0];
}

Of course, there is no vibrato or other stuff considered in this process but my point was to have some information to start working on a sequencer instead of having an automatic remix.

Hope it helps.

A little voice in my head tells me that J-War will reply with:

How can you use a MIDI-PAC to extract and log MIDI data from PSG, SCC or MSX-Music?
