The list that you are referring to is the Playlist for the audio player that demonstrates the MIDI files with various EZXs that are available from Toontrack. Some customers want to know what the MIDI will sound like with sound libraries they own.
From the EZplayer product page:
Used in conjunction with Toontrack solo and EZdrummer or Superior Drummer 2.0, EZplayer pro also becomes a stand-alone workstation for creating MIDI beats independently from your day-to-day sequencer.
Also in the requirements:
A virtual instrument drum sampler or hardware drum machine.
Audio Unit, VST, AAX or RTAS host application and professional sound card recommended.
Note that these requirements may not meet your virtual drum sampler requirements. Please refer to your drum sampler’s operation manual to ensure its requirement are met.
Sorry for the confusion.
