Since its inception, Pro Tools’s outstanding mixing board mimicry has made it the pro's choice for upscale audio recording and manipulation—the recording industry’s DAW, as it were. That’s its bread and butter and it’s very intuitive for traditional studio engineers. For artists? Enh. However, over the years, Pro Tools has acquired MIDI and sequencing abilities, as well as notation, so it’s a more than competent tool for creative purposes. In fact, the program’s in-line editing (editing done right on the track rather than a separate window) makes it a favorite of many.
Avid’s brave new world
Pro Tools fell behind in the home creative audio market not so much because of creative lacks, but restrictive marketing practices. Prior to version 9, you needed an M-Powered consumer audio interface that was limited to 48kHz, or expensive, proprietary hardware if you wanted to record at bit rates beyond that. Avid still markets the high-end hardware which is quite nice-sounding, but it’s no longer joined at the hip with the software.
