Since I upgraded to the newest version of Jupiter8V (2.5), any time I send Midi Controller signals to VST I hear crackles in the audio.
I also noticed that the VST seems much more sensitive to 'moving' and 'resizing', as these also generate pops. I'm running the instrument at 4ms as I always have.
My rig is as follows:
Windows XP (32bit)
Pentium i7 (Quad Core)
Emu 1616m (ASIO set to 4ms)
The crackles and pops do not happen in Moog Modular V, Arp2600V, ProphetV, or other plugins. They also happen regardless of CPU load.
Interestingly enough, if I moved the sliders using the mouse on the GUI.... The crackles do not happen. They only seem to happen when i use a Modulation Wheel to control Filter Cutoff or my Behringer BCR2000 to adjust pitch, Envelope Attack, Decay, etc values.
