Toy Keyboard Arduino Synth

I interfaced an Arduino Nano to a toy keyboard just for fun. The guts of the toy have been removed, I only wanted the keys and the PCB strip with the contact switches. Here is a link to a pic of the underside:

Here is the link to the updated VCF schematic with the R27 fix:

I will be uploading the Arduino code after I am sure I am happy with the current version. I think it's good to go. Also, I will be uploading the
Arduino interface schematic at the same time.
