b5bdac211a Ignore pitch > 0x1000 for pcm.
It seems to be supported only below 0x1000.  Also, drop optimization for
double for now, simpler this way and doesn't seem common?

dd434cd7c5 Optimize mixing samples at common pitches.
Doesn't seem to be a big help but may matter more on mobile.

8ded863231 Reset sampleFrac on keyon.
Since we're starting the samples over.

38053df4ca Don't drop the last mix of vag samples.
Wait instead until the end of mixing to end the envelope.

3899e18422 Always key on for 32 samples regardless of pitch.
Before it would be more or less depending on pitch.  It's always 32.

e006ab5b2d Don't read the first 32 samples after keyon.
The way I'm approximating this is ugly...

95fc9624b4 Fix PCM looping in SAS.
The parameter specifies where the loop restarts at.

55507d7844 Fix the default adsr sustain mode.
Probably doesn't matter, games always set it.

d097ac5394 Don't change height when keying off a voice.
Tests show that the height does not revert to the sustain level.

d53ab02e5b Don't change height immediately on keyon.
This replicates the PSP's behavior, which is a 32-grain lead in, plus the
height remains what it was before until processing happens.

684caa01ec Correct SAS bent linear curve.
Tests shows that at 0x30000000 it still goes up the full amount.

0265fc757d Flip and shift instead of signed divide.
Clearer than all those zeroes and maybe faster...

b398a84517 Attack switches to decay at max height already.
It does not wait until it goes above.

95a8af9e60 Decay does not switch to release at height max.
This can happen with an exponent rate of 0.  It stays there.

f981d39f94 Sustain defaults to 0, not 0x100.
Not sure how I came to that mistaken idea.
