I confirm what Dennis is saying...
This is an Elation product so it is best to contact them directly for information at the MidiCon Pro. I am not sure when the product will be launched for the European market, the units they had at LDI were non-stock items....I believe availability for the USA market is Spring 2014.
Thank you in advance - and yes it really does look like a great product to work as a wing for CueluxPro!
