Hey guys,

I'm hoping your engineering minds might help me figure out the best course of action. I want to control the sounds made by vintage game system chips. How hard would it be to modify a synth by putting, say, an NES chip in it? Would it even work or does an NES sound chip need a data signal?

The NES sound hardware is inside the CPU, not on a separate chip, so it needs even more than data: it needs properly timed and sequenced ASM instructions. People have used several methods to make this happen in real-time, the most successful of which has been Wayfar's midines. I have an NES synthesizer module coming out, but not for a while.

A SID is much easier to control since it just needs address and data signals clocked in. It also has many features beyond the NES sound hardware. The midibox SID covers it pretty well.

From what I here, the midiNES is pretty far backordered. My friend Brian is in a band called I Fight Dragons that uses chiptunes live, and he's ordered one over a year ago and still hasn't received it.

I wonder if any one has put a midines (plugged into NES circuit board) inside of a keyboard and rerouted all the control to controls in the keyboard shell. I might end up doing this. Anyone have any thoughts or cautions?

I'll need to figure out how to get the GUI onto a screen in the shell as well.

I'd love to hear anyone's thought's on this.

After looking more closely at the SID MIDIbox, that's way more than I need. Anyone know of a good diy project without the sequencer? Just the midi controls?
