It is working just fine, but you have to route signals to the qvca module in the grid or it won’t do anything. I provided a preset together with the update, put that preset on your card and load it up and look at how the qvca is patched to the LFOs.
The qvca user interface just shows 16 scopes, 8 for the inputs and 8 for the outputs. There are no controls to tweak. The module basically multiplies signals and outputs the multiplied result, and it does that 4 times in parallel.
When you are on the qvca in the network grid and press the P-page button you will see the qvca user interface. Press the p-page button again (as explained in the update notes) to bring up the user interface of the vst module again where you can load/unload plugins. This is how you “exit” the qvca screen.
Note that if you have a blank preset and put the VST module in it, and then go to the P-page, just selecting the qvca doesn’t do anything. You have to push the encoder to load it or press the Load 1 softkey. The Load 2 soft key is used for loading programs, after the VST plugin is loaded. The qvca plugin only has one (default) program.
