Performance improvements in 1.0.2

I've been testing 1.0.2, and even though it doesn't directly appear in the patch notes for 1.0.1 or 1.0.2, I think the duplicate stop performance issue has been fixed from 1.0.0.  Thank you, Modartt!

I'd like to see if anyone else can confirm this, but when opening duplicate stops, the cpu staying with 1% of the value of the single stop performance--including with couplers applied, and I can use full organ (the tutti piston) and all default couplers without audio breaking up, where I couldn't do that before.  (It hovers at 63% of cpu on my system at 96 polyphony and 512 latency on a three-voice fugue, which is substantially improved stability and performance for full organ.)  It also doesn't sound like the sound is getting amplified/over-dubbed either (though I haven't confirmed with an SPL meter), which is great!
