MR/ZR GETTING STARTED GUIDE 
MR/ZR Rhythm Builder 
 
One very cool feature of the MR/ZR series is that they can load new drum rhythms for the 
drum machine. The creative person in you might decide to program an entirely new set of 
drum patterns and post them on a users site or have them for sale. The sky is the limit 
when you have the right tools for the job. The tool you will need to assemble your own 
MR/ZR drum machine patterns is MR Rhythm Builder! It is a free utility that is available 
from EMU-ENSONIQ's web site.

It is very simple to use. First, you will need to create some drum patterns for use in the MR 
Drum builder. Create 8 drum grooves in your sequencer. Each sequence should be 4 bars 
in length. These will be your variations. You can use the 16-track recorder of the MR/ZR or 
you can use any other sequencer you like. All the drum parts (kick, snare, cymbals, 
percussion etc.) need to be on one track of the sequence. The ONLY track you should use 
is Track 10.

After you have created 8 four bar sequences, create 8 one bar sequences. These 
will be your fills. Each sequence (like the other 8 you created) need to have ALL of 
the drum parts on one track. The only track you can use is Track 10.  
 
ALL of the sequences need to be saved as .mid files. 
 
Launch the MR Drum Builder. 
In the SELECT FILE area, select the drive and folder that contains your MIDI files. 
Click on the first MIDI file you want as your first Variation pattern 
Click the ADD button to move your pattern into the MR drum patterns first variation 
location 
Repeat the above steps to select each of the 8 four bar patterns you created and 
move them into the Variations area until all 8 places are filled. 
Repeat the above steps to select each of the 8 one bar patterns you created and 
move them into the FILLs area until all 8 locations are filled. 
Type in the name of your pattern in the Title window 
Choose a Style selection (drop down menu) 
Choose a drum kit for your Rhythm (drop down menu) 
Then click BUILD 
 
The file that is created will be a .rbk file. That file should be copied to a floppy disk and 
loaded into your MR/ZR.
