Some of the musicians I work with are "computer phobic".
The solution was for them to get a hardware multitrack recorder. It has all the familiar features of a tape recorder and mixer, all in one.
There is still a learning curve, but once it is understood, it is just a matter of pressing the record button and making music.
Here is an example of a big one: Tascam DP-32SD Digital 32-Track Portastudio
One of the singer/songwriter guys I record uses a handheld 4 track digital recorder with built in mics.
He uses the built in mics to record his acoustic piano.
It has a mic input for an external mic that he uses for vocals.
He sends me wav files. The quality of the files are actually good enough to use in the recording.
