Casio SK-8 Slo-AD mod

This is a circuit that I have designed for the Casio SK-1, SK-5 and SK-8 sampling keyboards.

 

This simple mod enables you to increase the attack and decay times of the instrument preset sounds and samples. If you select a sound with a fast, sharp attack, for example, the piano or guitar sound, it will slow the attack and decay down, and make it sound synth-like and completely different to the stock sound!
