Hi again,
If you use either of these synthesizers, please grab the latest. The previous versions moved "gain" to a global parameter. I should have known better; this causes glitches in already-sounding notes when presets change. I had a similar problem last year with [polywavesynth], but forgot about it.
This is the tradeoff to using [poly] to manage voices; if you want the ability to change presets cleanly, most parameters (i.e., those stored to make up the preset) can only be changed on new attacks. I haven't thought of a way around this conundrum yet.
At any rate, the latest versions fix this issue. Sorry for any inconvenience.
