I have made I template for my LPX to control numerous of settings for all the pads A1-D8. I use the CC99, CC98, CC6 route for this (manual p.72).
At the current OS, the CC messages sent to the S2400 will only get applied when the machine is set to track override for the corresponding track and corresponding parameter.
I would love to have an added CC to turn on/off track override for all channels, for all parameters, so I can just select the pad and the parameter on my controller and just jam on (with) it.
