The source tree includes

• Synthino XM source code
• Arduino API and hardware configuration for ATxmega128a4u microcontroller
• LUFA USB driver with configuration for Synthino XM
• ported Arduino MIDI library
• simple USBMIDI library API that uses the LUFA driver

Building the source code requires the AVR GCC toolchain:

• Windows: Atmel AVR Toolchain
• Mac OS X: CrossPack for AVR Development

To build:

• 'make'

To upload to the Synthino XM device, hold down button 3 while powering device, then:

• 'make flash'

Utility required to upload synthino_xm.hex to the Synthino XM device:

• Windows: Atmel Flip
• Mac OS X: dfu-programmer

If you already have dfu-programmer installed (for example, via macports), then instead of the 'make flash' command above, you should run these two commands after holding down button 3 and powering on the device:

• 'dfu-programmer atxmega128a4u erase'
• 'dfu-programmer atxmega128a4u flash synthino_xm.hex
