SuperMegaUltraGroovy on Thursday released Capo 2.1, a major update to the company’s music app for Mac OS X.

[ad#Google Adsense 300×250 in story]Capo already allowed users to transcribe their music using tablature, but with the new version users can export the data from Capo in standard MIDI format. That file can then be imported into “applications that facilitate advanced scoring work,” according to the company.

“The ability to export MIDI really extends Capo’s reach into a musician’s workflow,” said Chris Liscio, SuperMegaUltraGroovy’s founder. “Because you can capture the precise timing of a performance using Capo, you can build a very accurate MIDI arrangement, or score, from a source recording.”

Capo 2.1 also brings back the classic waveform representation, which Liscio said was a very highly requested feature from users.

Capo 2.1 is available now as a free update to all 2.0 customers, and is a $19 upgrade for 1.x users. Capo can be purchased for $49 from the company’s Web site, or on the Mac App Store.
