README
README.mdREADME
This project contains various parts of a midi-organ. The project consists of four main parts:
- The Pedalboard: a 29 note midi foot pedal, mostly ARGO compliant. This odd number of notes was choosen because of size restrictions (I wanted it to fit under my e-piano).
- The organ console: contains stops, a lcd display, and all connectors and hardware to wire it to a PC. Up to three midi keyboards can be used as input devices, as well as the midi pedalboard.
- The organ desk: a framework for all the parts, contains speakers and some additional foot-stops. This is also designed to hold the PC.
- The software: A controller software which allows access to some special features of the hardware and sets up the software synthesizer.

Questions
How big is the PedalEncoder PCB?
It measures 125 × 38.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PedalEncoder use?
35 parts, built around the ATMEGA48-20PI, L7805 and BC547. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PedalEncoder KiCad files?
From the stefanhepp/eOrgan repository on GitHub, at the commit this page was made from: the board is boards/PedalEncoder/PedalEncoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PedalEncoder design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
