The [coll] object applies here I think; see Cycling74/examples/max-tricks/notes-and-pitch, there's a useful [coll] in there that you can modify to suit.

not much math, just have 7 [+] objects with the right offset. So for major:

0 2 4 5 7 9 11

where 0 is the first chosen note, in your example, C2. But it could be anything.

Have int boxes (probably restrict min and max to 0 and 12?) attached to each number box. Use a preset on the int boxes and you can have any scale you want. Use [zl group] on the output of the boxes to make a scale list, then you can use [zl rot] to transpose.

[% 12] is also useful with scale stuff...

I have an example called ScaleMaster which can be found here http://xfade.com/max/

It is a scale database with a couple different flavors of note quantizers.

more complex than I'll ever need.
