Diki,
I agree 100%...and just a little off topic but related...CONTENT is the biggest reason prodcts like Mediastation, OMB, LiveStyler etc find it difficult...If we ae all honest...who rally has the tech. and musical talent (AND the time) to do your own drum loops, styles new voices etc.

Content (sure, functions too) is a big reason we buy the arranger we do..or WS as far as that goes.

As an example my PA2XPRO has tremendous tools onboard for sampling & creating new sounds, creating styles, song book programming, tons of different edits, superb MIDI implementation.....AND pretty good content. Some available elsewhere.

But Yamaha has TONS of content built in and available elsewhere...I think that's the reason for their success.
(Don't have much experience with Keton, Roland etc)

Content is hard to come by and costs lots of $$..IMHO.
