Hi All
Here are a couple of Artists that might interest you.
1. Daniel Watt http://www.danielwatt.com/index.php?id=home he will be of particular interest to those who want to here Wersi, as in addition to his Spectra he also uses an OAS expander, (Currently OAS 6 but shortly to be updated to OAS 7) which also has extensive Akai samples installed, and also (If memory serves correct) the Colossus and B4 VST instruments. (Pavane and Aquarius feature the OAS Expander)
2. Ace Holiday http://www.soundclick.com/pro/view/02/default.cfm?bandID=534393 who plays both Yamaha and Roland keyboards. (So no bias here) and proves you don’t have to have one or the other to make music.
Hope you enjoy.

Bill
