Note: In this table middle C (60) is C3, not C4 as per ISO system standardized by Acoustical Society of America.
This conversion table doesn’t apply to MIDI note lists of the sort contained in the ‘MIDI Filter’ module. For those a simple ’10/127 x note number’ formula works.

The volts values can be fed to ‘Trigger To MIDI’ and ‘SampleOscillator2’ modules at ‘Pitch’ pin for example, the values can be calculated as well, but it’s not so straightforward and due to deviations product requires constant manual adjustment, the table saves you this tedious process, it’s accurate and verified
