I've been having a hell of a time getting the Faderport to work in Sonar.
See post http://forum.cakewalk.com/Annoying-Process-to-Get-Sonar-to-see-Presonus-Faderport-m3439279.aspx
and post http://forum.cakewalk.com/My-projects-are-toast-and-Platinum-is-unusable-open-case-326713-RESOLVED-m3476790.aspx
Tonight I was doing more troubleshooting and I was going between the AZController and the Faderport Controller and was unsuccessfull with both. If you read through my other postes you will see what I mean. The two main problems was Sonar would not see the Faderport unless i opened a Studio One project first. The other was more inportant where the Faderport was preventing my projects to open. In the Faderport plugin I noticed a checked box (Link WAI indicator and track strip selection) For the heck of it I unchecked it and saved under a new name. Low and behole Sonar is seeing the Faderport everytime and every project is opening. I don't know what this (link WAI indicator and track strip selection) does but I have to assume it is what was causing all the problems. Anyway I thought it may help others to know. I am hoping this finally ends these problems for me.
