Tanager AudioWorks, Inc. today announced the availability of their SongFrame Songwriter's Toolkit for the Mac OS X , perhaps the most comprehensive songwriting application available for songwriters and recording musicians. SongFrame provides expert help in developing interesting chord progressions, melodies, lyrics, rhythm, and overall song structure. The Mac OS X version follows on the heels of the Windows XP and Vista version released earlier. SongFrame serves as the primary notebook and collaborator for any songwriter, as well as serving as a musical writing partner for musicians who utilize digital audio workstation (DAW) recording or sequencing software. Songs are built with easy-to-use musical tools which focus on each aspect of the song. This, in combination with a song framework manager and track-based platform, make SongFrame truly unique. Chords, progressions, scales and rhythms can be auditioned and dragged onto tracks built specifically to hold this information. An Audio Track provides fast capture of elusive ideas, and a Lyric Track organizes the songwriter's developed lyrics in a musical context. The user can listen to the song as it is being written, drag and drop new ideas, and create endless alternate versions of any portion. When songwriting is finished, an export function creates audio and MIDI file data easily imported into any DAW recording application, complete with the final versions of all chord, melody, rhythm and audio tracks. In addition, markers for every song section and chord change will appear in the DAW's session file timeline. SongFrame is available for $149.99 as a download or a packaged DVD-ROM, either from company's webstore or a variety of music equipment retailers.. Customers receive both Mac and Windows versions for the same price.
