Hi Bachus.
The styles were a joke. They were worse than very bad, they had little or no intro's to them, no endings, very lifeless and badly programmed midi files. If you can imagine converting a Tyros 2 style through EMC styleworks for a low end Yamaha PSR model you get the idea, it simply doesn't work or sound good. The quality of the sampled instruments were very poor and were no way near the quality used in the Tyros 2, SD1, G70 etc. Fair enough I had a huge piano sample (2GB is it?) but this didn't do anything for me and neither did the VST organ plugin which was badly implemented with the way the instrument works. The sound output I can't comment on as mine had serious faults and I used to get dreadful buzzing noises or samples locking up on me.
Having heard the new demos on Lionstracs site, in my opinion the sounds and styles are still of a very poor quality considering that this instrument is up there with the top end arrangers on cost.
I've said it before, the idea is an excellent one but I don't think they will ever get it all working correctly. If you want plugins stick with Wersi at least they know what they are doing and their instruments sound good.
