Wouldn't you need a software editor for the S900 to edit that patch within the software seq? Does Cakewalk allow you to set controls within the software to send the appropriate CC's to the S900 for specific synth paramters?

Beaky.., why not use the onboard synth tools you already have in your S-900 to tweek the patch?
