Tuner module from Endorphin.es

The 1U Autopilot from Endorphin. es is a tuner module in a compact 1U format for analog oscillators. The module offers a tuner that tunes the connected oscillators precisely to the note "A". Simply connect the module's "Drop-Out" socket to the 1V/Oct input of the VCO and patch any waveform output to the reference input (Tune In) of the tuner. If a keyboard or sequencer is now connected to the module's key input and the tuner button is pressed, the oscillator tunes to "A". If you press and hold the tune button, the reference tone can be shifted from 440 Hz to 432 Hz.
