Not sure who needs to hear this, but I just found this #digitalPotentiometer after much searching. It's "low res" at either 7 or 8 bits, but it's $1.

It has a low supply voltage of 1.8-5.5V, and can handle signal voltage up to 12.5V. It also has built-in non-volitial memory to store the wiper position! All this means this should be more than useable for #audio projects.

Did I mention is $1?
