How Do I Add a Fader (liner pot) to a Kontrol F1? I really like the f1 but wish that it had a crossfader to round out the package. I have popped open the case and have found room to put the fader at the bottom. How would I go about adding a fader to the current PCB? I have looked through the forums and searched the web but haven't found anything relevant. I have found a location that is very similar to the MF expansion ports but the labeling is unclear. The label underneath the PCB holes is "XSYS_HEADER1" and I assume this is an expansion left on the PCB for mods, or greater use of the PCB by NI in the future. Has anyone modded an F1 or have any ideas as to how this can be done? Any help is greatly appreciated, thanks!
