MIDIbox Live MIDI Quantiser?

[sylwester]

I want to implement a stand-alone variant of http://www.maxforlive.com/library/device.php?id=196

What I want to achieve: I want to select quantize grid, feed clock to the core and play live, but with getting quantised output.

Has something like this been done? What's the best approach? I was thinking of using the NoteStack from MBSEQv4 and pushing/popping notes on the notestack
based on midi clock.
