About the Synth
My goal for this project was to capture the 2A03 sound, and then add features to make the chip more friendly to musicians. Call my program an enhanced "re-implementation" of the 2A03. It is an 2A03 freed from the limitations of the original hardware. The core 2A03 "sound" however is preserved and faithfully reproduced.
At it's core, the 2A03 contains 4 sound generation circuits:
To ensure that the sound was authentic I first read various online documents describing detailed operation of the chip. I found Brad Taylor's online technical reference document to be an invaluable source of information for this project. Using this information I then determined what was and wasn't needed from an audio perspective.
I've basically determined that there are three things that give the A203 it's distinct sound:
These are the portions of the 2A03 that are replicated exactly in the 2A03 Synthesizer.
Now, to "expand" the synthesizer I've added the following features. I've detailed how these features differ from a real 2A03.
I've considered possibly adding the following features in the future:
