Genesis to VRC7
« on: July 01, 2017, 03:54:11 am »
So, let's say i have an EXTREMELY Simple instrument that can be converted to Famitracker's VRC7. I wanna convert, but i don't know what some of the letters mean in the FM Instrument Editor.
I mean i can atleast guess that FB = Feedback and D = Decay etc, but what about DT and all that? can even be replicated on the VRC7? I need to know.

Pretty much, what I do (in 0CC-Famitracker) is that I eyeball it. I look at the ASDR and Mult. values of two of the operators in Deflemask (for both the YM2151 and YM2612), and approximate them in 0CC-Famitracker (for the VRC7). I was able to get an almost square-sounding instrument for the VRC7. By the way:
A=Attack
S=Sustain
R=I believe it stands for Release.

I never knew what DT stood for anyway, but I have made use of it for some of my FM instruments.

ALG=4
OPERATOR 1: Modulator
OPERATOR 2: Carrier
D2=31(Both operators)
(Use first two operators)

Amplitude Modulation: AMS
Vibrato: FMS
Feedback: FB
Modulator Level: OPERATOR 1 TL
Sustained: S
Wave Rectification: FB(?)
Level: OPERATOR 2 TL
Mult. factor: MULT
Attack: A
Decay: D
Release: R

DT means Detune, which makes an operator slightly out of tune with the other operators

Makes sense. Thanks, Genatari!

You can try, but you're not getting the same results. This is because of difference in the chip family. Genesis YM2612 is from the OPNx family, while the VRC7 OPLL is from the OPLx family, so there will be differences in ADSR and whatnot
