MessageCool! Should be easy enough to set up then, as Sonar supports the Mackie protocol. I guess you would ad the MackieControl control surface in the control surfaces dialog in Sonar and take it from there. There's an entire help book written that tells you how to set up this control surface. You will find the book in the : C:\Program Files\Cakewalk\Shared Surfaces folder Regards, Phil Muir P J Muir Productions, Music And Audio Production Telephone: US (615) 713-2021 UK+44-1747-821-794 Mobile: UK +44-7968-136-246 E-mail: info@xxxxxxxxxxxx URL: www.philmuir.com/
