1) how can one design a max patch which only lets through incoming notes belonging to a certain scale, such as D major scale?

2)how can one design a max patch which only lets through notes belonging to a certain scale, such as D major scale, and where every note played below midi note number 60 is being accompanied by a fifth and an octave above.

3)how can 1 design a max patch which adds 2 randomly pitched notes within an octave above an incoming note.

question-3

Number 2 and 3 are dead simple, look to the comparison and arithmetic operators. You can do whatever you want with these.

Number 1 is a bit trickier, but when I did this I used % 12 on the incoming notes, then sent them through [select]. The [select] had all the note numbers that weren't in the scale, so any that were would come through the rightmost outlet. In the case of a major scale, the notes are:

where 0 is "C" and 11 is "B", though it's abstracted to any major scale.

and anything that gets through is in the major scale. Making it "D major" versus "C major" or "X major" (just the raw set of whole-half steps) is up to you to determine, but it can be done with an arithmetic operator placed appropriately... like take the incoming note, subtract 2 (half-steps), then on through the % 12 and the [select]. This would give you D major.

If you want tons of scales, you probably won't want tons of [select] objects, so use a [coll] or a [matrixctrl], then you can compare the given note with the whole list using [iter] or better yet, one of the [zl] comparison functions. The [matrixctrl] is probably the best route as it gives the user a way to make any scale, and can have tons of presets stored in it.

[select 1 3 6 8 10]
