Has anyone had any success in emulating or sounding very similar to the second mega drive or an ad-lib sound blaster with their preenfm2?

Hi,
To do that, you have to know what are the FM spec of the ad-lib engine.
The chip used is the YMF262.
I just had a look at the spec (pdf can be found), looks like it's a 4 operator FM synth.
So use 4 operator algo.
I read quickly so I maybe wrong, but it seems it only has one Amplitude enveloppe.
So your carrier operator(s) must have the same enveloppe (can be copied with the PC editor).
( hold button 3 (preenfm2) to modify the env of all operators at the same time / in the tips here (https://raw.githubusercontent.com/Ixox/preenfm2/master/docs/pfm2_qs.pdf)).
And the modulator enveloppes must be very simple : value 1 all the time.
Amplitude modulation or vibrato can be done with the matrix modulation.
And i think you can add a little noise (by using more operators) and use the "crusher" effect to get a slighty dirtier sound if that's what you're after.
So no miracle recipe but you need to know how this card works to mimic the sound.

Can we do this on the FM3?

Sure it's "MENU" + turn encoders.
It works in :
EDIT > Oper > (ADS and R)
And also in
EDIT > FM > IM (to modify all IMs).
I just tried and it seems
"EDIT > FM > Mix" does not work although it should / Bug.
You will see the value turning Green (instead of Yellow) if several params are modified.

;D

ok, I've been messing with this for.... probably 40 hours off and on, and there's ALOT of timbres I can't get with 6 operators that other fm synths can get with 2..... in particular, a sort of metallic or more complex sound.
...Like, instead of getting more subtle harmonics, the sound just gets messier, or doesn't go anywhere....
EDIT: Nevermind... I figured out why.

Care to share? Might be helpful for other users. Gain too high, or something else?

hi there!
That’s exactly what i’m after. I’m a beginner at synth, but i love that FM sound (especially that Mega drive bass)
I’m trying to replicate that (it’s a 4 fm chip, well documented), but i’m having a hard time to figure out how you do what you can in FM.
So if you’re up to sharing your patch, i’m really curious :)
Thanks!

Ok. so this may be the link we need for sega patches
