I wish I had the full version of this. If you play guitar this is majorly sweet. Play any song through this software and it tracks the rhythm, lead and gives you all the chords and notes. Allows you to jam with your favorite songs at any speed.
It lets you find the guitar in the mix, and extract it right out so you can hear it in isolation. You can then slow it down in perfect pitch to learn it easier.
With the pitch tool you can transpose by up to 12 semi-tones up or down in semi-tone increments without affecting tempo, and yes, you can change that too.
Learn the songs you love. Practice at any speed. Develop your technique. Jam with your favorite bands.
