I have a potentiometer connected to a DIY microcontroller board which sends MIDI data to my Axoloti. I would like to control the Filter Cutoff Frequency with more than just 7 bits. In the patch the Filter Pitch parameter is set to a CC number. Controlling the parameter with a 7 bit data MIDI CC command works fine. How can I control the parameter with 14 bit?
Thanks for suggestions in advance! Sebastian
How to control i.e. Filter Pitch via MIDI with high resolution?

Either midi/in/cc hr i or midi/in/cc hr ii.
With each object you have a brief description...

as an aside - and I apoligise if I can't explain the technique - have a look on the net for Dave Smith talking about smoothing midi when using analog filters. I know there's at least a few interviews where he has talked about using smoothing techniques when applying midi to an analog filter.
A practical test to explain this in real hardware if your local music store is friendly enough: Take a controller like Alexis keytar controller that has a midi output you can rapidly sweep from 0 -128. Plug this into something like an Access Virus Ti - the resulting output sounds raw and choppy because of the type of controller and the lack of midi smoothing on the Access Virus. Compare this to any Dave SMith Instruments synth with an analog filter - the DSI will sound smoother. This is a practical example of midi smoothing on a filter. the same midi input with no smoothing vs smoothing.
What im drawing this log bow for is it might help for ideas on how to use the extra bit depth maybe apply some drift (?) to the higher resolution signal 
Id have to go check, but Im pretty sure the TI does smooth midi, based on its "Adaptive Control Smoothing" setting.
this probably wouldn't apply to automation, but Id assume that would be a function of the DAW, given that automation values are floats.
