The MidiGurdy is an electronic hurdy-gurdy. More information about the instrument can be found on http://midigurdy.com and the support forum at https://forum.midigurdy.com

The repositories in this organization contain all the source code, configuration and sounds used on the instrument. The code is split across multiple repositories:

• midigurdy/mg-build - Configuration and scripts to build the MidiGurdy software stack
• midigurdy/mg-core - The main program, sound generation, user-interface etc
• midigurdy/mg-effects - LADSPA effects used in the MidiGurdy sound output
• midigurdy/mg-initialdata - Default SoundFonts and configuration
• midigurdy/mg-web - The web-interface of the MidiGurdy
• midigurdy/linux - Linux kernel and special MidiGurdy drivers

This repository - midigurdy/midigurdy - does not contain any source code and is only used for documentation, wiki and issue tracker.

Building from source

The MidiGurdy build-process uses buildroot to cross-compile all code for the ARM architecture. The following is a short introduction on how to compile it yourself or a recent Debian or Ubuntu system.

1. Make sure you have all required packages installed:

sudo apt-get update
sudo apt-get install --no-install-recommends -y git wget file python cpio unzip rsync bc build-essential \
          ca-certificates device-tree-compiler libncurses5-dev cmake npm libcap-dev imagemagick

2. Create a base-directory for all MidiGurdy related files:

mkdir ~/mgurdy
cd ~/mgurdy

3. Check out the midigurdy/mg-build repository:

git clone https://github.com/midigurdy/mg-build.git

4. Create and configure the build environment:

mg-build/scripts/create_build_environment.sh mg-build build

5. Switch to build environment and start the build

cd build/output
make

6. Sit back and wait for the build to finish... depending on your machine this will take between 30 minutes and a few hours.

7. Create the firmware update image

~/mgurdy/mg-build/scripts/build_system_image.sh ~/mgurdy/build/output/images

You will end up with a midigurdy-X.X.X.swu update file which you can store onto a USB stick and use to update the instrument.
