Not being a member of the twitter-verse, I wasn't sure how else to contact you.
I see that you're working on a Performer version. Hooray!
Just some general info.
They haven't updated the firmware for a year or two.
I have had no bug-like experiences with the ViSi app, other than its amazing inflexibilty.
I love the console; it's super configurable, but hate the ViSi app.
After having used the SC UI24 'app' I dream of that sort of flexibility for my Performer.
I have a lot invested in the SI system, and I don't want to change to something else.
If I can help or contribute in any way, please feel free to contact me.
There is a community of Soundcraft users here waiting for your product.
