Note quantization & filtering

[thepcman]

I will add a sharp infra distance sensor to my MB. I'll linearize it's output with respect to distance and at this point i need some guru help:

If anyone had dealt with roland d-beam controller (that's actually nothing but a sharp sensor) it has a mode "active expression". When you turn on this mode, it produces some definite notes according to sensor output. But it does not go over all notes, it can follow a certain list, for ex. a Em7 over 3 octaves (E,G,B,D,E.... goes on). I wonder if it's possible to program that kind of a quantization to MB64 directly, or should i embed it to sensor output circuitry. If the second one is the solution, has anyone any ideas how to design a good interface for it??

It would be much, much easier to do it in the software.

The technical term for such a mechanism is "force-to-scale" or "harmonizer"

The application which perfectly matches with your requirements is AC Sensorizer:

There are also videos which show how it works
