I want to build a digitally controlled audio mixer. It should have
for each channel 3 tone controls, sound level, balance, monitor level
so the digitally variable resistor chip has to be cheap.

I have been looking at X9MME and X9CMME. It is a 8 pin DIL with 99
resistors and is controlled by three pins, step, up/down and chip select.
The main advantage is that it is small in size. The disadvantage is 
that it can't be set to a absolute value or be read. It costs $10 each
in sweden so the cost is a bit to high.

Another solution would be to use a DA converter together with a voltage 
controlled level control chip.

Any suggestions of other parts?
