DEMO KETRON SD40 

I've been a dealer and made my living using KETRON products for over 40 years, and I can honestly say no Yamaha , Korg, or other keyboard can come close when playing live with ease of getting your groove 's and sounding like a real band . Great product ! !

What a cool demo, everything sounds so good from this SD40

Mais um Demo Maravilhoso, Obrigado carissimo José Carlos

VERY GOOD REVIEW MODULE ... SHOW THE POSSIBILITY OF SOUNDING ALL ACCORDIONS HARMON BAYAN ... THANK YOU ..

Can you tell me which midi control keyboard do you use with the sd40?

Está com um bom peso de som. ;)

What style used at 3.00 please?

Very talented..... I need advice please. I got the Sd40, but I can't get the voice to work... Does it have to be connected to keyboard to work? I play Oud, oriental instruments similar to guitar and I connect it to the system, but I just was able to have the styles to work... Any idea please?

Boa noite amigo Onde eu encontro este módulo pra comprar? Abraço.

Cómo se puede poner eso en un teclado marca Roland V3???
