EZplayer pro from Toontracks is an Audio Units, RTAS and VST plug-in that functions as a MIDI organizer, multi-track arranger, and format conversion tool for compatible master application. With it you can convert between mapping formats and collect all of your MIDI clips into one convenient location, the EZplayer pro Browser. You can use the plug-in to preview those MIDI clips with your favorite drum sampler, and drag and drop them directly into your host to construct custom drum tracks.
You can also use the multi track Arranger built into EZplayer pro to put drum tracks together, on as few or as many tracks as is required. Using an intelligent cataloging system, the software is capable of isolating percussive instruments from the MIDI files, allowing you to re-combine patterns from different grooves to form new beats. Additionally, you can step through variations and fuse them into performances that can be re-used in future compositions.
EZplayer pro can also function as a standalone workstation for creating MIDI beats independently from your day-to-day sequencer when used in conjunction with Toontrack solo, EZdrummer, or Superior Drummer. The software includes a generous amount of percussive MIDI files played by David "Fingers" Haynes and Per Mikaelsson (drummer of the Claustrophobic EZX). The software is included with every copy of Superior Drummer 2.0, but can also be purchased here separately.
