I am attempting to use the voice chorus block and have a couple of questions about it's use.

First, what are the two outputs? It seems that one could be LFO and one Feedback. How

would I use these in a design?

Also, I don't see the LFO radio buttons changing any values in the SigmaStudio capture

window. It writes 8 parameters, but these parameters are always the same no matter what

LFO radio button is pressed. Along this line, the only value I see changing is one parameter

called "ch_loop_gain" when I select the Feedback radio button.

The two outputs are actually AudioLeft and AudioRight. The cell takes a mono input (vocals) and produces a stereo chorused output.

I'm not sure about the LFO control. I confirmed that it doesn't seem to be updating any parameters. I will check with the software team.

I checked with the software team and it seems that this was a control GUI problem. The problem is now fixed and the update algorithm will be working properly in the next SigmaStudio beta release.
