# [sdiy] Quantizer project.. incoming CV's switching point to change to quantized output CV's ...

```I'm starting a CV quantizer design and am wondering

Let's assume a normal quantized semi-tone scale:

All the incoming CV's are quantized to semi-tones like this:

incoming CV 'around' C, output quantized CV -> C

incoming CV 'around' C#, output quantized CV -> C#

incoming CV 'around' D, output quantized CV -> D

and so on..

12 equally spaced output quantized intervals. OK.

But if the quantized scale output is a TRIAD like

C-E-G-C-E-G-C, etc... ( 3 quantized intervals)

where are the switching bounderies of each incoming note CV's

to change to the next outputed quantized note ?

This question is for ascending and/or descending notes..

Same question for a quantized PENTATONIC major scale output like

C-D#-F-G-A#-C-D#-F-G-A#-C, etc.. ( 5 quantized intervals)

I would think of dividing the octave range with

equal intervals with the number of intervals

inside the actual quantized scale..

For example:

That's 3 intervals

1 octave = 1 volt

so 1volt/3 intervals = 0.333v between each quantized notes (??)

or

PENTATONIC major scale C-D#-F-G-A#-C

That's 5 intervals

1 octave = 1 volt

so 1volt/5 intervals = 0.20v between each quantized notes (??)

But... I don't think that is working this way..

I think I must keep the incoming CV interval sizes

and use them for the quantized switch points.. (???)
