I travel a bit for work, and have just bought a cheap (<$40US), shortscale electric to cut down and make into a travel guitar. I have a recording setup at home but between work and family I rarely get to use it, but I'm going to get a new computer for work-on-the-go within the next few months hopefully. So I'm thinking about getting a very basic travel-friendly recording setup for songwriting sketches.
Requirements: As few pieces of equipment as possible (already have mics and phones, no monitors needed), SMALL (ideally would all fit in a laptop bag including ultrabook, bus powered USB interface with 2 in/out (must be 3.0 compatible), midi controller keyboard.
Budget: Around $400US excluding computer (which will be bought for/through work and will probably be a mac so Garageband will cover DAW duties)
Focusrite 2i2 + Akai MPK? Behringer UMA25S? Any other suggestions?
