Hello,

Ok, I can put info into an array, but how do I get it out and make it do something. If I put the 8 notes of a number of different scales into an array and want to retrieve them at different times..how do I do that?

E.G..sometimes I may want the minor scale...sometimes I may want the major scale...

You will want to use as many arrays as you have scales (or refill the arrays appropriately). I think, you will be better off putting pitch classes that characterize the scales rather than the actual notes and do processing afterwards.

I figured out how to read and write to files...but the arrays seem useless...is it possible to bang an array and connect it to something like the "noteout" object so that it plays it contents?

you need to call the locations for specific notes (or pitch classes, as I mentioned).

see atached example.

If I store values of chord notes in an array..how can I compare these values to the ones that are coming in from the "notein" object(using the "poly" object to get all notes from "notein").

i don't see why you use [poly]... [notein] lets all the notes through. I don't have a MIDI setup but if I'm correct, every pitch gets through twice (note-on and note-off) so you need to filter that with [stripnote]. After that you can compare the note coming to anything, really... try [select] or [=] or [<=] etc...

I want to recognise chords input from the MIDI keyboard and get PD to play a little melody over them, somehow by using arrays. I've been looking at them all weekend and still I'm no closer to getting anywhere!

The simplest way to recognize chords is to pass your notes through [sel]. However, you need to define, first, what constitutes a chord. Hint: [timer] could be used to establish the rate at which the stream of notes is coming in so you can filter out long (say > 80 ms) gaps between notes and consider them not chords. Then define rules for establishing the chord analysis and eventually inversion, register etc.

I know it's vague. But your problem is, too :) .

HTH.
