Ok, but what I try to say is :
EVERY brand (e.g. Ketron, Solton, Gem, Roland, Yamaha etc) has good quality demo-pieces to show potentials of equipment.
Wersi & Lionstracs have not !

In fact they are a couple of years behind compared to other music brands (in soundquality and styles)

The open systems are built upon an ordinary PC concept, right ?
Be honest and tell me how many years are PC's 'up to date' nowaday? I'm computing since the eighties and learned every three years an upgrade was needed because of new developments in hardware and more demanding software.
So when people say "These open systems allow you to keep the hardware forever and with only new software users stay uptodate! ", I only can smile and think 'come on, wake up !'

In my view serious/realistic thinking musicians don't purchase these PC based stuff, because they are not interested in 'building' a keyboard. They want reliable/solid machines that sound great.

Those who do purchase must have lots of money, feel 'pioneers' and try to convince 'ordinary' musicians they are a kind of old-fashioned.

Magica Alfa your song sounds OK, but how many days took it to find the right settings?

While using a normal modern keyboard it's a matter of minutes.

I'm lurker at this forum for ages and read many discussions with- and about Lionstracs.
Lionstracs showed a nasty attitude on top of the fact that the product itself is extremely poor IN MY VIEW !
