Engine quality affects sustain on some patches

[martinog]

Hello,

I've found that the global engine quality setting has a drastic effect on certain patches, making them sustain for a lot longer time.

Repro steps:
- Go to Settings, notice the default Engine Quality setting of 'Draft'
- Go to the first patch in Factory Presets 'AR Ballad Arp TP'.
- Play it & note the sound
- Go back to Settings, change Engine Quality from Draft to Best
- Play 'AR Ballad Arp TP' again. Now, with Engine Quality at Best it sustains for a lot longer.

Not sure whether this is intended or not, but it had me scratching my head for a while. Other patches, like 'AR Berlin School' don't have such a drastic difference. Another patch that shows this behavior is 'AR Lush Arp TP' from Factory Presets.

I'm using SynthMaster 2.7.6,64-bit
