I am attempting to translate sequences of switches to specific noteouts. basically, i am building a wind controller based on a standard boehm fingering system. i've linked 8 contact switches to max with an arudino board running arduino2max. all of that works fine. the hard part for me is trying to determine the best way to interpret the key sequnces. ie. pack, unpack, matrixctrl or something else that i have not considered taking into acount my blinding noob-ness.

I thought about using matrixctrl. my first thought was to put these key sequnces into the grid but i have not discovered how to make them "trip" the right note at the end. do i use it with the pack and unpack? or possibly use trigger? i need that when i press a particular sequnce of keys, it some howresults in a single particular midi note.

again, i am sorry for the overtly noob question, but i have read thru the manual so many times now and i confuse myself more with each read.

for instance;
C-key 2
c#-no keys
D-keys 1,2,3,5,6,7
D#-keys 1,2,3, 5,6,7,8
E-keys 1,2,3,5,6
F-keys 1,2,3,5
F#-keys 1,2,3,6
G-keys 1,2,3
G#-keys 1,2,3,4
A-keys 1,2
A#-keys 1,4
B-key 1

though I didn't really understand what you are after, it looks like you

are looking for the coll object...

I am trying to interpret the pressing of a sequence of keys into a related midi note. ie, if i press button 1 and button 4, at the same time, i get Bflat, but if i press button 1 and button 2, i get A. my controller has 8 buttons. its basically an emulation of the boehm fingering method. I'm trying to figure out if i should store the button presses as integers or maybe text symbols, then interpret those into sequences of button presses, because each button only sends a 1 or an 0. so maybe i will try converting the bang into a variable of some kind, then interpreting the result into a midi note.

I'm getting a little closer but any help is greatly appreciated. thank you for your reply, i am reading up on the [cool] object right now. i will report back.

i've included the layout in this message.

I would approach by encoding the keys into one number. Here is a brute  
force way to do this:

It is not as difficult as you think. have a look at this:

I used pack to make a list of all the key settings, and then compare the

list with settings for all the different notes.

note that I used the [Lsame] object from the Lobjects pack written by Peter

the thing i've got to get used to is that there are so many ways to do just about anything with this software. i studied the coll object like stefan suggested, which started leading to the pack, unpack, table and iter objects as possiblities. i cant wait til i can say how easy this program is to get result, as you did, jahroen. that was exactly what i am trying to do.

thank you all. i will post pics and music from the thing, when i get closer to finishing it. if you'd like the see the controller itself (its not amazing or anything, but it puts a face to the code) you can see it on my myspce profile at www.myspace.com/onyxashantisinterstellarribshack its the third slide show down on the right.

that's it!  thats what i was looking for.

you're creating a nice controlling apparatus as I can see! I hope to see it

working someday, keep us informed on the list!

Hey onyx,

thanks. i will. if you're in california, i will be attempting to use it at the MakeFaire next weekend. thanks again for the insight.

oh, by the way jahroen, this is what i ended up with from the example that you sent to me. as you can see, it was absolutely EXACTLY what i am trying to do. thanks again.

Don't let me discourage you from using that solution, if it's working 

for you, but it strikes me as over-complicated, and hard to extend. 

Here's one based on treating the switches as bits, encoding them into 

a number (as I described before), then looking up the numbers that 

matter via a coll to get the pitches. This one is easily extended to 

look up any old combination of switches, to generate other notes.

you're right. i'm learning that the strength of max is its ability to create many different ways of doing things.

it kinda beats up my ego because i'm used to feeling sufficiently "clever" when it comes to music software but this whole "all possiblities" paradigm takes some serious practice. your solution is very similar to the one that thomas henriques used to create his meta-ewi. my problem is that i know what all the components are; the trigers, bangs, integers, etc...i just get confused when it come time to pick a solution.

thank you for your patch. it will give me something to study tonight. I look forward to being able to return the favor one day.

You are absolutely right chris.
This is probably the most effective way.

May I suggest Lbyte for quickly encoding bits into numbers as Chris explained.
