See this FAQ regarding the EZD 2 percussion:

http://www.toontrack.com/faq/how-do-i-trigger-the-ezdrummer-2-percussion/

I read that and it makes no sense to my question.

I created this video that shows how I take off all the drum pieces on a particular MIDI drum beat and then add only Hand Clap, Shaker and Tambourine. All within EZDrummer 2 which is loaded in Logic Pro X.
I then drag that MIDI region from EZDrummer 2 into Logic Pro X on the track that EZDrummer is on. I delete the MIDI region in EZDrummer 2 then play Logic Pro X.
As you can see in the video, everything plays fine, no problem.
Now back to my original question, The MIDI Manufacturers Association has defined in it’s General MIDI Level 1 Sound Set
Hand Clap at D#1
Shaker at A#3
Tambourine at F#2

but EZDrummer 2 has them defined as
Hand Clap at C#-2
Shaker at D-2
Tambourine at D#-2

It plays fine if I use the above notes that EZDrummer 2 requires, but why didn’t EZDrummer use the defined notes from the General MIDI Level 1 Sound Set from the MIDI Manufacturers Association.

One other thing, from http://www.toontrack.com/faq/ I couldh’t find that link you posted. It’s almost like you have to know it’s there.

Because EZdrummer 2 isn’t a General MIDI sound module.
All Toontrack libraries are drum-centric (with the exception of the Latin Percussion EZX) and use an extension of the General MIDI standard to be able to handle an extended set of articulations.
All the drum libraries will play back GM drums MIDI correctly but the Toontrack MIDI will not play back correctly with your GM module. Feeding GM percussion MIDI into Toontrack plugins will not sound as intended.
The adding of the Percussion pads in EZdrummer 2, is a clever way to add percussion to your EZdrummer 2 tracks without ruining the compatibility across the Toontrack range of MIDI and libraries.

This is from the EZDrummer Manual
3.8 ADDING GROOVES TO THE BROWSER
MIDI purchased directly from Toontrack will be added automatically using the installer included with those additional products. You may however want to extend and customize the library with 3rd party MIDI packs or your own.
The process is very straightforward: select the ‘Add Folder to
User Libraries’ entry from the Browser’s contextual menu and
locate the folder you would like to add on your hard drive. The folder
and its content will then appear at the bottom of the Browser, on the left hand side.

The 3rd party MIDI packs that I’ll add are General MIDI Level 1 Sound Set for drums, what you’re saying is they won’t play properly. If that’s true, can you update your manual to state that because it’s misleading. The 3rd party MIDI files do contain clap, shaker and tambourine.

FYI- Logic Drummer generates General MIDI Level 1 Sound Set notes. I’ve matched them up with EZDrummer 2 and they’re all there except for the three I mention.

This is for anyone who’s using Logic Pro X, I wrote a simple MIDI Plug-in Script to handle the incorrect notes for clap, shaker and tambourine in EZDrummer 2.
