Chiptune Guitar Synth Project
I did find a neat link of a guy who made a Guitar Hero PS2 guitar controller thing, and the chord buttons were connected in series. The different chord buttons, when two or more are pressed, create different notes. There was also a whammy bar that made the chipnotes act like guitar notes with reverb. He also added an audio jack to connect it to a speaker or an amp.
The one part im trying to figure out is how to make this instrument more of a synth than a one sound chiptune device. It might be possible to replace the "strum bar" thing on the GH controller with some additional buttons that make different kinds of 8-bit sounds while the whammy bar is used by the palm. The sketch ive made should shed some light on what im talking about.
With all of that being said, is there anyone out there who could help me design a schematic or something that can help to make this thing better than what i could design by myself? I got the skills to build the instrument, but not the skills to design the electronics and circuits that go with it. Any help is greatly appreciated!
