Potent13 | Buy (

The Potent13 is a user-customizable, high-resolution, potentiometer-based MIDI controller with an analog feel. Play a software MIDI synth, and shape the sound with smooth, high-resolution control. Add knobs to a hardware MIDI synth for instant control of parameters otherwise hidden in menus.

Because each knob has a specific visible state, a musician need only look at the pointers on each knob and is freed from looking at a screen for visual feedback. The potentiometer positions are read at a 10-bit resolution, which is eight times higher than the ubiquitous 7-bit MIDI CCs. It is not uncommon to hear “stair stepping” when using 7-bit CCs, whereas 10-bit control yields a smooth, analog-like sonic experience.

A web browser based configuration tool enables the user to customize the MIDI messages generated by each control. Each knob is independently configurable to transmit MIDI messages of the following types: NRPN, CC, Pitch Bend, System Exclusive, and MIDI Clock with a variable tempo. The button toggles between on and off and can transmit MIDI messages of types: Start, Continue, Stop, Note On, Note Off, and System Exclusive.
