James,
Yep good way to do it...BUT, anything, anything at all, your fault, my fault, nobody's fault (Quote from a movie!) that crunches the CPU during live play...enough that the CPU can't get the sound into RAM...and...Dropout happens.
The OS and complete system must be optimized and have safeguards to try to prevent this.

But, it can happen in the right situation.

IMHO, with Windows this is more concern than Linux? The CPU speed and all other aspects must be way overkill to hopefully prevent this.

Then, what about very heavy polyphony????
And who can really predict how many notes may need to go at the same time?
