I have a Korg Nano Kontrol which in previous versions of Vegas has worked as a general controller. I could control volume, pan, as well as transport. In V19, the transport works but the volume and pan do not function correctly. The level or pan jumps from one setting to another (like 27 to 33). It does not follow smoothly with the fader. Is the midi function broken? Pan will jump to like 15% left and 6% right although it does seem to vary. Also if I focus off Vegas to another app, when I return the External control no longer functions on existing tracks. The left red bar goes away (indication external control)
