Why is the write_wav executable 1.5MB even in ReleaseSmall, even with the progress bar stuff commented out? It should be like a couple of kilobytes. Is it the GeneralPurposeAllocator?
Make a module that lets you artificially alter the sample rate and resolution of the input stream.
Updated: I added decimator, which lets you change the sample rate, but doesn't do anything about the resolution, I guess that would be a separate module.
Maybe as part of this, add an visual indicator to the examples of the number of "active" modules.
This is the function that tries to sync the timing of the main thread and the audio thread, so that when you press a key, the impulse is scheduled to play at an exact sample offset, which should be the time the key was pressed plus the duration of one mix buffer.
Right now I have all this code disabled so that all new sounds play at the beginning of the next mix buffer frame.
At least for square wave instruments this would probably be an improvement.
maybe just if there is a note-off and then a note-on.
When a voice slot is taken over, don't just play a new note on it, somehow cause the reset method to be called. Otherwise e.g. the old note's envelope is resumed, noticeable for example if you have really slow attacks.
For example, if you have a long release duration, and you release the note at the peak of the attack, you'll get a long, loud release, even if your attack & decay were both short and your sustain volume was low.
I guess I need to run the attack/decay alongside the release, and take the min of them or something.
