I am running latest JV software & driver on Win7 x64, installed on two high-end machines and both setups having the same problem: Korg EXP-2 expression pedal and Vox VFS-2 footswitch work very inconsistently, as if JV software misses 75% of inputs from those two devices, or reacts with a delay. Expression input sometimes gets picked up 10-15 seconds later. JV software works well otherwise.
The reason I think it's JV problem is because I ran JV software on different systems, used different cables, and both the footwsitch and the pedal have similar issues. I wrote to firstname.lastname@example.org about the problem about 5 days ago and haven't heard from them.
Will be thankful for any suggestions re: how to resolve the problem.
