I have a Roland GW-7 and just bought a Yamaha MOX8 (yay! I love it!). Can anyone give me some guidance as to how to best set up the Tom Saywer growl? I use both keyboards to gig and I've tried a few different things and nothing really gives that long sweep and deep slow growl. I'm kinda new to synths, so I'd like to learn about the different waves, etc.
