Overlapping notes, pitch

Hi,

I'm making a CV out device in max to control my modular.

One of the problems i'm having is overlapping notes, i'd like to create those famous 303 slides.

The problem is (when you look at the attached image) that it outputs the following data string for the pitches:

72 (note C4 on) 84 (note C5 on) 84 (note C5 off) 84 (note C5 on) 84 (note C5 off) 72 (note C4 off)

The problem lies between the two C5 notes, I'd like to make the pitch go back to 72 since that is the only note left playing. But it doesn't (hear the attached audio file)

Anybody got an idea how i could code that?

I also had the problem with overlapping notes, that a note off message of the second note would also cut off the first playing note. I fixed that with a bit of java script, might be usefull to others as well. it's below:

var v=0;
var counter=0;

if (jsarguments.length>1)
    v = jsarguments[1];

function msg_int(v)
{

    if( v > 0 ) {
        counter++;
        outlet( 0, 1);
    } else {

        if ( counter > 0 ) {
            counter--;
            if( counter == 0 ) {
                outlet( 0, 0);
            }

        }
    }
