If you have further questions about the FaderPort with Samplitude, Sequoia or other Magix application, please know that Magix develops their own Native device profile for the Faderport. PreSonus Technical Support is unable to assist with such inquiries as PreSonus does not develop the profile. The Magix support team has requested us to let our customers know that any questions about the FaderPort can be addressed by referring to your hardware integration guide found with the Samplitude / Sequoia (or other Magix application's) user guide. Other questions can be sent directly to the Magix tech support group who can assist. http://www.samplitude.com/en/contact
