Anne (or others),
Can I make a recommendation for the EOS/Ion client software?
It would be really awesome if we could use something like the Griffin PowerMate with the client software along with the x-keys. It would give you a physical encoder, but there would need to be a way to swap it among the 4 virtual encoders.
A link to the manufacturer's page is here: http://www.griffintechnology.com/products/powermate
Let me know what you think.
