Arduino Project: Sync Nanoloop 2.5 and 1.5 to Mackbook running Ableton Live

Hello, I am completely new to circuitry, soldering, and Arduino. I know how to read schematics on a basic level and know the basic terms. I need an interface that will control tempo, start and stop universally between a Gameboy Micro running nanoloop 2.5, a DMG running nanoloop 1.5 and a Macbook running Ableton Live 8 master suite. I don’t know where to start or what I’ll need. I know I’ll need a board (no idea which one), a schematic, proper cables, conductors, resisters, capacitors, something to house the guts, a fine-tip soldering pen, and the software for programming. I don’t know the specifics on any of these though. I tried to commission someone to make the interface for me but to no avail. Is this a project an amateur can possibly undertake?

Cheers,
Riley
