I have both Pluggo and Hipno, and I notice that just a few effects make snapping and popping sounds, especially those that dive deep into some intense frequences and modulation. Has anyone experienced this? For instance, Drunken Sailor in Hipno does this. All my other VST work great, and I have a screamin' notebook with lots of RAM (2gig), Intel duo core processors (2gHZ X 2), plenty of buffer (set to 1024)...so it it is not a buffer or processing issue. I am using the Indigo IO soundcard, but I found that the snapping and popping occurs with other sound cards and notebooks as well, such as Soundblaster Audigy 2 for Notbook on a different notebook. The issue is less of an issue with Pluggo, but I noticed there is no forum for Hipno here.
A peer of mine said that he experiences the same with a few Hipno effects as well.
