Quantizer that outputs a trigger on note changes

General

I don’t think there is one in the MetaModule library, is there? A bit surprising since many hardware quantizers do this. Let me know if I’m missing one.

This is probably much larger and more complicated then what you are looking for, but the Venom Non-Octave-Repeating Scale Intervallic Quantizer outputs triggers on note change.

Thanks Dave! Very cool device but yeah, seems like overkill for my purpose.

For anyone who’s interested, here’s the modular version I figured out thanks to a Modular Grid post:

  • run the output of the quantizer into a sample and hold triggered by a very fast clock
  • get the difference between the S&H output and the quantizer output using an analog math module
  • patch that difference voltage into a comparator that triggers whenever it’s greater than 0 – i.e. whenever there’s any difference between the the current value and the sampled value.

Or simply use a Venom WinComp to detect the change directly.

Use the WinComp module context menu to enable “B normalled to A - 1 sample” option, patch the quantizer output to A input, and get a 1 sample trigger at A<>B output. If you need a “proper” trigger, then convert it to a 1ms trigger using VCV GATES.

Even better! That “B normalled to A - 1 sample” feature is clever.

FYI, I did look for a comparator that could do something like this but WinComp doesn’t show up in a search for “comparator” in the module finder.

@danngreen I wonder if it would be possible for the search field to include the library description text as well as the name and tags?

Yeah, unfortunately VCV has a restricted set of tags, and “comparator” is not included. The VCV library does search the description (both web and within app), so it works OK there, but doesn’t help with the MM.

I agree, it would help if the MM module finder also searched the description.

Maybe using slope detector from count modula could do the trick?

Yes, actually it’s quite easy. I’ll add a button to show/hide the description field, too, so there’s no mystery why certain modules come for a particular search.
