Arduino "MIDIsync" MIDI and CV Master Clock

At least running on

Should be compatible with the MIDI-Shield from Sparkfun.

Libraries are included as git submodules. To clone the project and it's submodules please do:

$ git clone https://github.com/gretel/MIDIsync.git
$ cd MIDIsync
$ git submodule init
$ git submodule update

Building and uploading can be done easily using platformio.

Currently, python 2.7.10 is required as well as pip.

Please edit platformio.ini first to reflect your serial port.

$ pip install -U pip setuptools
$ pip install -U platformio
$ cd MIDIsync
$ platformio run
...
