SEGA 315-5660 (Yamaha 3438 IC)

So I have successfully desoldered a SEGA 315-5660 IC from a Sega Genesis. I wanted to harvest its audio chip which is a Yamaha 3438 IC and use it for an Arduino application, however SEGA decided to integrate it into a single IC

Here is the pinout for the 315-5660: 315-5660 - TechWiki

I would like to be able to generate at least 4 channels worth of audio but I don't know exactly where to begin, audio interpolation is a very unknown area for me.

Here's the results, successfully removed!

Any suggestions? or even where to begin to work with producing audio using midi ICs or FM ICs? (preferably FM)?

Your wise, guru super-powers will be greatly appreciated :wink:
