As the originator of this thread, I want say how grateful I am for the excellent posts! I'm really learning a lot. And VPC1 is getting delivered tomorrow!
You guys are a good bit beyond me on many things, though I may refer back to these posts in the future. But I could use answers to a couple of basic, practical questions, related to the below progress points I wrote earlier:
1. Got asio4all working, set for 2.9ms latency (128 samples) with good quality sound for the Blues demo. Am using optical s/pdif connection from computer to amplifier. The HD analog speaker output works also, but I found I needed a ground loop isolator and that attenuated the signal a lot.
Optical S/pdif avoids the hum/noise, and I read that it introduces very little latency, is that correct?
Tonight I think I will try this even lower, 64 samples, but does it really matter much at this point? Isn't 3ms quite good?
3. While playing the Blues demo, my I5 processor is loafing along at about 12% on just one of the 4 logical processors. I did set my system for "high performance," and apparently Windows 10 and my computer are more than adequate. I set my sample rate in Pianoteq to 44100 Hz instead of 48000, is that reasonable?
Is there any practical reason to sample higher than CD quality, for just live playing?
4. For now I set my polyphony to 96, hopefully that is plenty for the kind of basic playing my son and I are capable of.
