HOW I CAN CONTROL MY SYNTH IN CUBASE SX!!!!!
You need to open a midi plugin that deals with controllers, I'm at work right now, so I can't tell you the exact name, but after you have assigned the cc parameters you want, set the Lightwave to respond to the desired cc's, and go to the midi channel in SX and click the little + button opening an automation track. From there you select the control already set (usually volume) and click on 'more.' From there you will have a list of all the cc's available. I'm a little rushed to type this all out right now, so if you need more in-depth explanation, you can email me privately
