SuperMegaUltraGroovy announced the release of Capo 2.0 Tuesday, a new version of the software that allows you to reverse-engineer recorded music. The new version adds many new features, including the ability to quickly tab out guitar lines,auto-detection of chords, and the ability to add your own chords by hand.

Users can use songs in their music library, drag them into Capo, and then set to work deconstructing them to learn the guitar parts. You can also use it to change the key of the song, slow down and loop passages, and more.

Features:

• It’s your music
  No longer do you have to rely on the musical tastes of others to learn music. Drag songs right from your music collection into Capo to start learning them.
• Detect, and Enter Chords
  Figure out the chords in your music using Capo’s sophisticated chord detection routines. Or, enter your own easily using strings like ‘bbmaj7’ or ‘f#maj9’.
• Pitch Adjustment
  Capo lets you adjust the pitch of your songs—so you can change their key or fine tune them to match your instrument.
• Music Export
  Take your Capo-adjusted music with you. Export speed- and pitch-corrected audio to your iPod, and play along when and where it’s most convenient.
• Tab it Out!
  By simply drawing atop the spectrogram, Capo will generate tablature automatically for you. It really doesn’t get much easier than this!
• Markers
  Use keyboard shortcuts to mark verses, choruses, bridges, and other important points in your songs so you can return to them later.
• Looping
  Repeat difficult sections slowly, playing along with your favorite artist. Speed up gradually as you get better.
• Effects
  Capo lets you modify panning, adjust a 10-band graphic equalizer, and apply vocal reduction to help you isolate the parts of the music you wish to learn.

The main Capo page has a video you can watch that demonstrates some of the new features.

Capo 2.0 requires Mac OS X 10.6.x (Snow Leopard) due to the developer’s extensive work in harnessing OpenCL. The company offers the software as a free download, with a purchase mechanism built into Capo 2.0 for those wish to purchase it (i.e. keep it).

Capo 2.0 is priced at US$49.
