AudioCR has released Capture MIDI, an application for Mac OS X designed to make retrospective MIDI recording a system wide feature.
With Capture MIDI one should not need to track the recording button or search in retrospective buffers in their DAW. Instead they can preview, drag and drop the ideas back to their music sequencer or even playback them via armed track.
Includes audio/MIDI file browser.
Price: $6.99.
