Digital Orchestrator Pro merges a robust MIDI sequencer, a multitrack 
digital audio recorder (the number of tracks is limited only by the power 
of the computer), and digital effects processors into one seamless program.
Digital Orchestrator Pro sets a new standard for pro desktop music 
production by adding dozens of new features to Digital Orchestrator Plus - 
Electronic Musician's best digital audio sequencer of 1997.  In addition 
to feature enhancements, the redesigned toolbar interface provides even 
more control to enhance the creative process. 

Digital Orchestrator is a simplified version of Digital Orchestrator Pro, 
offering all the basic features at a lower price, including a MIDI 
sequencer (unlimited MIDI tracks), digital audio recorder (up to four 
tracks of digital audio), digital FX transforms, editing features and the
ability to print sheet music. 

Version 2.x of the software is known as "Digital Orchestrator Plus" 
("Digital Orchestrator Pro" is version 3.x).

A demo version is available for download.
