I am working on building a prototype for a simple 4-track recorder. It would be a cross between a Yak Back [0] voice recorder and a Tascam DP-004 [1] mixer.
My 7 year-old has gotten into music and is trying to record his own ideas. We have found the existing tools to be either too simple (Yak Back) or way too complex (Tascam). I want to make him something that has a simple interface, few buttons, and simple recording/mixing. The idea is to avoid the software programs like Garage Band and Logic.
