Superpiggy prototype

Just assembled and tested the follow-up of the Piggy. It’s the … yes, very obvious name here … “Super piggy”, or Super Arduino Piggyback Synthesizer.

Like previously announced it features an enhanced VCO, which can also do rectangle wave with variable duty cycle and 4 additional potmeters for hands-on ADSR control. The result is a bit “chiptune” like but with the low-pass resonant filter, of course.

Buttons and LEDs are used to select and display VCO mode, and loopable ADSR. See the screenshots below. Yes, there’s our logo on the PCB, finally 😉
