how to set YAC #2 as the first YAC ?

Recommended Posts

Hi guys

i'v build an OPL3 board, buying readymade PCB,

but i have only one YAC512, and i soldered it on the PCB has shown on this image from the Thorsten tutorial : mbhp_opl3_1.jpg

but i realized after that : "on my PCB this is the place for the second YAC, so i'll have only outputs 3 & 4 !

nevermind, i won't take more risk with the YAC, i let it there. "

my two outputs #3 & #4 are working fine (with the Testtone app)

Now my question :

how can i set my only YAC (OPs 3 & 4) as the main YAC, so the CS will show me OPs 1 & 2 ?

is it clear ?  :-\

thanks strid_one  ::)  but i'm looking for a safer solution, i don't want to desolder and resolder it, i'm too scary with this little piece of 90's electronic !

of course if it's the only way.... i'll do it  :'(

I'm sure you could do some firmware mods to make the app think it's talking to one pair (of channels on the OPL3, not the YAC!) when it's talking to the other.... But honestly I'm not interested in spending time on that, when the real solution is to get it right in the first place ;)
