PlingPlong – A portable synth

Posted on Thursday, October 31st, 2013 in project logs by DP

PCB-r1 Another cool project by Mats the PlingPlong, a two octave touch keyboard with four channel polyphonic synth:

This is a small (10x20cm 4×8″) portable battery-operated synth with a two octave touch keyboard and four voice polyphonic digital sound. I’m using two microcontrollers on the board – a Microchip PIC18F44K22 for the user interface and a Atmel ATMEGA328 for the sound generation. The PIC18 is using the internal CMTU module for capacitively sensing the 24 touch keys. It is also in charge of scanning the 15 tactile buttons, refreshing the 15 status LEDs and the 7-segment displays, and polling the Rotary Encoder.

Files available at github.
