SuperMegaUltraGroovy has updated Capo for Mac OS X (10.6 and higher) to version 2.1. In this release, Capo gains the ability to export MIDI transcription data, the waveform representation of audio has returned, and playback commands can now be controlled via learned keystrokes or external MIDI hardware.

Capo 2 was the first app to allow users to transcribe their music to a notational representation using tablature, according to the folks at SuperMegaUltraGroovy. Now, in 2.1, users can export their data out of Capo in the standard MIDI format, and use it to incorporate transcribed solos into MIDI sequencers, or import the data into applications that facilitate advanced scoring work.

Capo 2.1 now allows users to set and manipulate their loops with an always-visible waveform. The new version also adds the ability for users to train a set of new keystrokes, or assign MIDI commands, to control Capo's playback.

Capo 2.1 is available now as a free update to all 2.0 customers, and is still a $19 upgrade for 1.x users. Capo can be purchased for $49 at http://capoapp.com, or on the Mac App Store. A free trial is available for download at http://capoapp.com .
