I couldn’t find the Poly Dance program so I guess it’s from an additional sound pack.
Program size and CPU usage aren’t really related, it’s more about voices and polyphony. If the program size is 0 kb, that means it’s a program that’s only using the internal synth and no samples.
Some Halion sound packs are copy protected and limit your access to settings, but there are 2 ways to alleviate this problem.
-
You can turn on voice management under the program’s sound tab to limit polyphony.

I presume this is a program with a long release time, that’s usually where the buildup occurs. So if you have access to the amp envelope release time via the zone tab, quick controls or a macro window, try shortening the release significantly.
