Increase Knob resolution?

But in my application receiving the events, I only get an update every 3 degrees (same whatever the bit depth I use)

Is this an hardware limitation?

It’s not a hardware limitation. The hardware is good for 10 or 11 bits before noise creeps in.

Note your max value of 127. That matches a 7 bit integer range. (Note also how this impacts the displayed step size, showing that only one quarter of the resolution is being utilized.)

I don’t know what software you’re communicating with, or how, but you’ll need to adjust that max value to be correct for the chosen bit depth, and then you’ll need to adjust the code you are using to send data so that it carries all of the bits.

In MIDI this often requires separating the seven least significant bits from the others and communicating each separately, for example.

thank you very much for the answer

I'm communicating with an custom application I'm coding

I tried increasing the Max value to the suggested High resolution, but didn't see any changes

I will try again, thank you

How are you communicating the value from the grid module? What specific MIDI messages are you using?
