Well, mine also does it, and i think it’s perfectly normal.
Your VCF attack must be at 0, and your decay fairly low, it’s the filter envelope that’s clicking.
If you don’t like it you can either raise your VCF decay, or raise your VCA attack, and I guess it would solve the problem.
I agree with Embryo. It’s just the filter attack clicking away. My other analog synth does this too (a Roland SH-09). It think it’s fairly normal. Some VAs actually have a function to add the click to bass patches to get that ‘authentic analog feel’ - Zebra 2 for instance (and the Virus come to think of it, although they call it ‘punch’ or something.
This. The beauty of really fast analogue envelopes is that you can choose to have this click, or not, depending on your settings. If you carefully increase the volume envelope attack or filter invelope decay (perhaps using Precision Mode on the LP for precise adjustments), at slightly longer time settings you will then reach the minimum possible envelope times on these clickless VA synths.
The LP (and SH-09 and other analogues) simply have faster minimum envelope times than most any VA. A sound level change that approaches instantaneous will increasingly sound like a click or pop.
