CVlyzer - a “Multimeter” for the Drambonaut

catherder

Born out of the need to know what note a certain CV level in Drambo represents.

Analyse Drambos CV signals:
– Show Octave and Note.
– Select Voice.
– Oscilloscope with two modes.
“Input” shows the raw CV signal from the probe input.
“Delta” shows the difference between the input and the expected value for the quantised note. Very useful to check the pitch accuracy of self made modules.
The “Multiplier” is to get around the limitation of only two digits behind the decimal point of the scopes value display.

Awesome.

I'll download this and give this a try.
I had designed something similar, basically a per note precision adder
across all octaves to keep my external filters and oscillators in tune.

This is really cool for dRambonaut modular heads.

Thank you.

My pleasure @Gravitas ! Let me know if you find any bugs or inaccuracies.

Great idea with the precision adder. I think I am going to improve my patch by not using that switch as the main comparator to get the notes. What comes to my mind is something like: FullRectify(CVinput - NoteCV) > AccuracyThreshold
If this goes to zero we have a match for the note. The advantage for this would be an adjustable accuracy and it would be easy to implement a "not in range" warning.

It was much needed because it was slightly irritating getting them to scale correctly across the octaves.
I'm going to give a once over before I let it into the wild.

I'm learning something here myself.
