Wrong terminology

[NS-Clone]

you using wrong method to select algorithm

there is no ANY Amplitude modulation
in 2 operator mode it's can be named as Additive synthesis

for 4 operator mode
this AM/FM switches completely nonsense

it's different patches that completely cannot be described as AM\FM + AM\FM

and you can't get algorithm that actually do this "AM"+"AM"
(on OPN you can)

you need graphical selector like

and MAIN problem
it's wrong names of output operators in different algorithms
i'm put volume to operator that named "carrier"
and get silence....

correct naming

but in 4 operator mode this "carriers" depends on 1 fnum
so maybe? it's better way to named it as "output" operators

Hello!
Interesting explanation, yea. Speaking about 4op mode of OPL3, it somewhere weird unlike OPN family, and to change the mode is need to select a combo of AM/FM flags on both pairs. Actually, I used this wrong terminology from various documentation including Yamaha's that's I used as a reference. I'll check this deeper soon, and I'll try to revise the overall stuff to resolve this problem. Thank you for the explanation!
