In Sound.py, it appears that you may be changing the parameter named frameNum to index, which I am OK with. However, there are still references to frameNum. Is that correct, or an oversight? For example, I see frameNum in lines 279, 284, 296, 301, 312, ... 418, 420, 428, ...

@dllargent I can change those if you would like, but I didn't see much of a need to. The instances I changed had situations like this:

• setSampleValueAt() has a parameter index (the function called this method)
• setSampleValue() had a parameter named frameNum that index was passed as when setSampleValueAt called it

I deleted the setSasmpleValueAt since all it did was call setSampleValue. and changed setSampleValue to setSampleValueAt and renamed the parameter to index to match any calls with explicit parameters.
