Attention

This is the documentation stub to the upcoming TBD V2 release.

It is incomplete and subject to future changes.

Calibration Procedure

Preparation

Make sure you have a well calibrated 1V/Octave CV keyboard available 0V corresponds to C0 2.5V corresponds approx. to F#2 5V corresponds to C5 -5V may not be achieved, in this case your TBD cannot be calibrated for bi-polar CV use Or have a CV generator available which can be adjusted to precise voltages Elektron Analog 4 or ornament and crime work well for this purpose An adjustable lab voltage source together with a precise multimeter does the trick as well Allow for TBD two CV ins to be connected at the same time to the calibration voltage source

Procedure

In the main menu, hit the “Edit configuration” button to enter the configuration tab Hit the “Reboot, calibrate CVs” button → TBD will reboot in calibration mode, the LED blinks red Turn CV pots all left, apply 0V to CV in jacks → single press trig0 Turn CV pots mid position, apply 2.5V to CV jacks → single press trig0 Turn CV pots all right, apply 5V to CV jacks → single press trig0 Turn CV pots all left, apply -5V to CV in jacks → single press trig0 Turn CV pots mid position, apply 0V to CV in jacks → single press trig0 Turn CV pots all right, apply 5V to CV in jacks → single press trig0 TBD is now calibrated and will reboot to operating mode

Backup / Restore

You can backup and restore your calibration data e.g. prior to a fresh calibration or system update by hitting the “Calibration Backup” in the Configuration page. A new page will pop up, here you can down/upload calibration data (JSON format). Videos https://www.youtube.com/playlist?list=PLB5iCbhcvJ2qdD7s1o9wsvQ9qtsCUWVLR
