I recently bought an M-Audio Keystation 88es MIDI keyboard (I’ve wanted to learn to play piano for years, but strangely have always been drawn to strings – electric guitar, acoustic guitar, bass, violin, and, for a short while, cello).
It works brilliantly with Garage Band, but the speakers in the Macbook are small and tinny. So I plugged it through the hi-fi. It sounds fantastic. However, I really wanted to leave the keyboard set up in the spare room, where there’s no hi-fi. So I started to think about getting some computer speakers…
