Hello everyone! I've been working on a really simple circuit where a Pic Microcontroller makes writes to a YM2612 chip, which in turn happily dumps out an audio signal. The patch that is programmed is the "Grand Piano" that is defined at the bottom of the SEGA2.DOC Technical reference manual. two nights ago I made the very first sounds, and last night I made a programmed c scale and tonite I got a midi interface working where KeyOn/Off and Pitch are Recognized. Here are some unpolished demo videos of my progress so far: http://www.youtube.com/watch?v=p63t3O9LIsc http://www.youtube.com/watch?v=TOsozYpKqhY http://www.youtube.com/watch?v=0JSV9F905Fs so what, you may ask is the goal of this project? The overarching goal is to create a synthesizer module out of the YM2612 which is entirely controlled by midi. After that, I'm want to explore having the system read VGMs. I'm trying to get my hands on some SN76489 chips to fully realize this next device. So with all that said - what other protocols would be useful to interface with the YM2612/SN76489? I'm having a blast building this stuff so I'm looking for exciting ideas. also, I'll be updating this post whenever I have something new to flap around.
