I often create notes for the higher range in a 2 to 2.5 octave range. I often grab notes from the same source (quantizer) for the bass, but find sometimes there are too many higher notes for the bass effect I want. What I needed was a way to reduce the notes to a single octave. Although this technique could reduce 3 octaves to 2. I know there is probably a module that does this, but I took a stab at creating an Octave Nutralizer using comparators.
The input range is 0v - 2.99v and the output is equal to the input minus anything over 1.00v and 2.00v.
Input - Output
0.25v - 0.25v
1.25v - 0.25v
2.25v - 0.25v
It was fun to figure out a solution.
