Hello Spalding
Harmony Music should have sent you the OAS 6 Demo disc by Stephan Weiler, but as this is now water under the bridge, they missed an opportunity.
The latest Demo CD (Which is for OAS 7) has been done by Mark Whale, (If you follow the link under the style links, it will take you to the Wersi site where snippets of the disc can be heard) and is in the final production stages.
You should also find that from the middle of this year, most Wersi Artists will be using OAS 7 and it will be featured on their CDs. (OAS 7 was a really big upgrade and so it has taken time for the Artists to get in to the Groove so to speak)
I also believe that things are afoot in the UK to bring the sounds and demos of OAS 7 and OAA into the virtual world. (I will post when I have more details)
Regards

Bill
