I've downloaded and already installed these to try it with
http://www.cykong.com/CubaseSX/SXpanels.htm#Roland MKS-50 Juno + PG-300
http://www.ctrlr.org/page.php?p=ddb (PG 300)
but found a commercial one here
http://www.vst-control.de/MKS-50v.html
I've been emailing him for about a week, no response - so I bought it using the site shop thinking it may be sent out automatically via email, but it's done manualy I think, anyone got any experience of vst-control.de?
Otherwise if it doesn't come through I'll put in a Paypal dispute and get my money back and use the freeware ones instead(well ones a Cubase device panel, never used one before)
Any thoughts...?
