hold down shift and press track
in the 2nd row, press the encoder that reads "plugin"
press track one or two more times
now, whichever track isselected in sonar or on the mcu, those plugins are controllable from the C4. use the slot up and slot down buttons to switch between plugins within a track and use the track R and track L buttons to switch between tracks.
if a plugin has more than 32 params, use the bank buttons to reveal the other params.
i toggle between plugin control and functioon control using the "Function" button
this makes it quite useful!
works with every vst i have (i have alot).
contact me if u have trouble
