I'm starting to learn Max and I was hoping to be able to build an arpeggiator that could send midi at different rates; regardless of which note I press, I want the first note to sequence at a rate of let's say 1/8th note, the second key to sequence at the rate of a 1/16th note, the third at the rate of a 1/4th note – and so on. Depending on the number of keys being pressed down, the rate of the next note shall be based on that.

I can't really figure out how to make this work; I've used the [borax] object to keep track on the amount of keys being pressed simultaneously, but I'm having some problem with the routing. 

As I said, I'm an entry-level Max user, all help is appreciated!

How do you define first, second etc note ?

And what if you hold 4 notes, then release the second and insert new one ?

In my eyes that are more important things to sort, before looking for solutions.

I'll post some stuff for storing and sorting held notes when I get back home.

do you sort them by pitch?
Or by order they came in ?

I would like to sort them based on the order in which they came in.

If I were to hold 4 notes and release the second, I would like the previous 3rd and 4th note to sort themselves as the 2nd and 3rd note, thereby filling the gap of the second note that was released. The new note inserted would then be the new 4th note. 

Thanks for your reply!

To answer your question, let's say: 
1st note = quarter note
2nd note  = eighth note
3rd note = sixteenth note
4th note = half-note
5th note = whole note

If I were to hold 4 notes and release the second, I would like the previous 3rd and 4th note to sort themselves as the 2nd and 3rd note, thereby filling the gap of the second note that was released. The new note inserted would then be the new 4th note. 

Hopefully this reply made some sense, 

You need storage of held notes - I guess including velocity

and second object holding delay time between steps.

Both can insert, add and remove - renumber items

that can be done with few objects.

First thought is coll or umenu..

Uses coll to store held notes, umenu for delay times, counter -> jit.cellblock

I have no idea what you intend to use to start / run /stop, or sync the

arrpeggio, but the storage alone should help you get going.

this is one example.
