This article is for this model FaderPort:
The community over at Renoise created their own support for Faderport Classic.
You can find out more information about it here.
If you have further questions about the FaderPort Classic with Renoise, please know that Renoise Community developed their own Native device profile for the Faderport Classic. PreSonus Technical Support is unable to assist with such inquiries as PreSonus does not develop the profile.
Other questions can be sent directly to the Renoise tech support group or their community forum for assistance.
