2.1
Left, Right brackets and backslash to change/reset pitch by semitones (Thanks NS for formula!)
comma and period to seek.
Instrumental and acapella tracks are auto muted on load. It is assumed that these tracks contain mixdowns of the vocals and instruments, thus are unwanted.
Tracks that are muted now tell you their muted status.
When tabbing, you are now told a track's volume.
Volume of muted tracks now saves properly.
Soloing readded.
Paths with quotes surrounding them are now handled.

2.0
Rewrote entirely in Python with Synthizer.
Adds support for MP3.
Adds volume control for master and individual stems.
Removes soloing

1.1
now comes with small stems example.
Adds support for ogg, though I still recommend 44.1K wav or ogg and still mono.
Adds key to quickly find a stem in the loaded stems.
Adds key to turn off speech verbosity.
Adds key to unmute all.
Soloing now works as it would in a normal DAW, when you solo a muted track, it unmutes and remutes when unsoloed, and all other muted tracks stay muted after unsolo operation.
