uMIDI calibration

Hi. New here, and new to Eurorack. (oh what have I done :slight_smile: I’ve just started my journey with a humble few modules, but the uMIDI will not give me 1v per octave rendering it useless. How do I calibrate this thing? TIA.

Hi Smidi,

If your µMIDI was not calibrated you should return it to where you purchased it for a replacement, or we can issue an RMA# to have you send it back to us.

It is possible to perform this calibration yourself, but you will need a Voltmeter.
