welcome to the proud GENMDM owners club

Very strange behaviour - I must have stuffed up apologies. I'll have a look at it once I get a chance.

Also, link in first post fixed

It makes me think...does your vgm loader convert to midi prior to sending midi to the genmdm or those it sends directly registers writes ?
because if it is vgm to midi in real time...it opens up a lot
anyway looking good!
thx for the comment between

So the midi out of your max patch contains raw midi data converted from the vgm, that is great so if we send the midi out to a synth or whatever it will receive midi notes / per channels + cc ? That is huge , so The psg midi data for exemple to anything that received the right channels?

I'm not being clear enough, sorry.

In the case of PSG data, this is always just a single byte.

In the .VGM file, this single byte is logged as "0x50 dd" where dd is the data nibbles used for the PSG byte for that entry.

What the Max patch does - and of course it sounds simple NOW but it took me half the morning - is extract those single byte entries, and time them based on the delta timing entries.

This stream of single bytes is encoded as MIDI data - specifically of the form:
MIDI Control Message:
controller value = PSG data & B01111111;
controller number = PSG Data & B10000000 >>1;
channel = B00010000;

This leaves room for YM2612 OR YM2413 data in the form of:
controller value = YM data & B01111111;
controller number = YM address & B01111111;
channel = ((YM address & B10000000) >> 5) | ((YM data & B10000000) >> 6) |  page);

A Kind of reverse genmdm, yes lots of work indeed but could be fun!

Between
-Added .tfi export to FMDRIVE 2612 Vsti  also save as plain text decimal data
One ot two more thing to work on for the SSG part.. and we are close to the release
