Tides is calibrated for accurate pitch tracking by feeding known 1.000V and 3.000V references into V/OCT in a button-triggered routine

To make Tides track pitch accurately as a VCO, it must be calibrated against a known voltage reference. The procedure: disconnect all CV inputs, then connect a well-calibrated keyboard interface or MIDI-CV converter note-CV output to the V/OCT input, leaving all other CV inputs unpatched. Press buttons [A] and [B] together to enter calibration (the first LED slowly blinks orange). Send exactly 1.000V to V/OCT and press any button (second LED blinks orange), then send exactly 3.000V and press any button. Tides now maps the Volt/octave scale correctly. This two-point calibration is why V/OCT tracking is reliable across the module range.

Examples

Patch a precise MIDI-CV converter to Tides V/OCT only. Press [A]+[B]. Output 1.000V, press a button; output 3.000V, press a button. Tides is now calibrated for accurate V/Oct pitch tracking.

Assessment

State the two reference voltages used to calibrate Tides V/OCT tracking, and explain why all other CV inputs must be disconnected during the procedure.
