That's always a good question. 'Closed' arrangers and keyboards have their faults, but when they say 128 voices, you get 128 voices, no matter WHAT sound is being used... (and yes, I know a four element voice uses four voices!)

I'm just curious, but when CPU overloads occur (from using some very intensive VSTi's and effects, etc.) does the MS multi-task, and only close down on the overloaded VSTi, or does the whole thing glitch out?
