Hi there.
I've tried the IDC a month or so ago and all I could see were midi files by Yamaha and some other companies and loads of styles (thanks to Steve Marsden for helping me set the connection up as my Firewall and router had a mind of their own that night lol).
I can't remember the cost but they were not expensive. It seems that Yamaha midi files have a demo available to listen to although they don't last long, but some of the other companies were not offering a try before you buy demo. I don't use midi files myself so I was mainly interested in new styles.
The styles had demos but to be honest they dont last long and you dont get to hear all of the intro's and endings to them, so it's hard to say if they are good or not. To me some sounded like styles you can freely get off web pages and they were possibly 9000 pro and T1 styles.
I can remember Yamaha stating that there were going to be 10 new Tyros 2 styles available for free or to purchase every month from the T2's release.
The T2 came out in the UK early November so that should be 10 released in December and 10 in January, so where are these 20 new styles because I can't see any of them on any Yamaha site?
COME ON we all need new T2 styles even though the internal ones are amazing
