This does not need to read any existing formats (just a basic json format) yet and it doesn't need to sound dead-on yet. It only needs to sound like what you expect a sid chip to sound like for now. To that end, implement the oscillators, amp and egs and filter in terms of how this spec describes the behavior. (the filter on the SID is a real analog filter, which is why it sounds awesome. for now either use a simple fft-based filter if it's ready or leave it out pending us having a self-resonating filter)
