The ottopot is a MIDI controller featuring 8 high-quality dials. It stands out from other similar devices due to its high resolution with 14bit MIDI CCs and a quasi-1:1 mapping from physical movement to CC value. While software support for 14bit CCs is good, hardware support is lacking, which is why the creator built their own controller. Building the ottopot requires soldering and electronics experience, but the process is expected to become easier with the next version, which will include a PCB. The cost for materials and shipping is estimated to be around 220€. The article provides detailed instructions for building and setting up the ottopot, including replacing the grease in the pots for smoother turning.
