And I decided to port a couple of FF7 songs to the Sega Mega Drive using Deflemask. The Mega Drive's chip is definitely weird and interesting, some things are ridiculously easy to do and others almost impossible. I like to cheat and use a single 4-op instrument to simulate 2 2-op instruments, in order to get more channels.
What do you guys think ?

EDIT : Changed the song according to comments (see below).

Nice.

I liked FF7REACTOR the best of these. The timpani + drone orchestration works very well.

In FF7PAROCHIAL I wish the glassy keyboard sound had a longer presence; the attack portion of the sound is really good, but it seems to fade off really quick to me.

The sound pretty nice, but Parochial and Reactor seem to do something wrong - at some point they end up playing one single note for eternity (on multiple Genesis emulators, I made a ROM with these since I don't have any VGM player). For Parochial it sounded like an organ and for Reactor it was noise.

Not bad! (Thanks snarfblam for the tip that VLC plays .vgm.)

That's because I was lazy to insert some keyoff events. But I now fixed it. It's actually very touchy, I only reduced the decay by 1 and it already makes a lot of difference - reducing by 2 would make it fade too long.

Maybe that's a problem with Deflemask' VGM export ?

Could be Deflemask allows you to do things the hw won't allow? You mention cheating, maybe it was that? (No, I don't understand what 4-op and 2-op mean)

I doubt. "Cheating" means abusing the chips to create 5th chords with a single channel, and I'm pretty sure the hardware allows that.

I've done exactly that sort of "cheating" for just-intonation perfect fourths (3:4 frequency ratio) and perfect fifths (2:3 frequency ratio) in TFM Music Maker. Use the algorithm that looks like this:

Code:
[Mod1]->[Car1]--.
                |
               (+)-->[Out]
                |
[Mod2]->[Car2]--'

Correct me if I'm wrong, but I think it's algorithm 4.

This will produce intervals so long as the ratio between the "multiple" values for carrier 1 and carrier 2 is something like 2:3 or 3:4. To ensure the same timbre for both voices, make the ratio between the "multiple" values for modulator 1 and carrier 1 the same as that for modulator 2 and carrier 2. Then you can make major, minor, or suspended triads and their inversions by using this instrument on two channels, with carrier 2 of the second channel muted.
