Hi in this project I have been able to output the data from 8 pots through a 4051 to 1 pin on the arduino and unpack the data in max/msp.
Here's the working code for 8 pots and the max/msp patch to read it into separate boxes is below.
int MuxPin1=2;
int MuxPin2=3;
int MuxPin3=4;
int AnaInPin1=4;
//Declare variables
int MuxVal1 = 0;
int MuxVal2 = 0;
int MuxVal3 = 0;
int BinVal = 0;
int N = 0;
byte data_send = 0;
byte data_in = 0;
//BinPat is used for figuring out the High / Low (1/0) values of the MUX control pins
int BinPat [] = {000, 1, 10, 11, 100, 101, 110, 111};
void setup()
{
//Initialize digital pins and serial communication speed
pinMode(MuxPin1, OUTPUT);
pinMode(MuxPin2, OUTPUT);
pinMode(MuxPin3, OUTPUT);
beginSerial(19200);
}
void loop() {
if(Serial.available() > 0) {
data_in = Serial.read();
if(data_in == 76) {
readPotValues();
}
}
delay (10);
}
void readPotValues()
{
for (N=0; N<=7; N++) { BinVal = BinPat[N]; MuxVal1 = BinVal & 0x01; MuxVal2 = (BinVal>>1) & 0x01;
MuxVal3 = (BinVal>>2) & 0x01;
digitalWrite(MuxPin1, MuxVal1);
digitalWrite(MuxPin2, MuxVal2);
digitalWrite(MuxPin3, MuxVal3);
data_send=analogRead(AnaInPin1) / 4;
Serial.print(data_send);
}
Serial.flush();
}
here's the max/msp patch this has not been tested on max 5:
(just copy the text and go open from clipboard in max)

I am trying to get 16 to work the same way and will post the code as soon as it is finished. Hope this all helps.
