I am in the process of completing a Casio PT-87. Modifications to include a LFO and filter circuit. More to come in a few days for this one!
Also in the works is a Pulse Width Modulated (PWM) Filter with added LFO. This will be a standalone table top type unit housed in a die cast enclosure.
Additionally, I am working on another Atari Punk Console. This circuit will have added features to manipulate the output wave shape. It will be housed in a unique, recycled, precision motor controller enclosure.
