+
+ The MR-Rack can play special demonstration songs to give you an idea of how terrific it sounds.
+
+ To Play the MR-Rack Main Demo
+ 1. Press the Audition button, and hold it down.
+ 2. While still holding Audition, press the Save button.
+ 3. Let go of both buttons.
+
+ In an unexpanded MR-Rack, the display shows:
+
+ Hit ENTER to Play:
+ MAINDEMO:MR Internal
+
+ If you've installed any Expansion boards or a ROM card containing MAINDEMO-type
+ demonstration songs, your display will differ. Turn the Value knob counter-clockwise
+ until the display looks as it does above.
+
+ Note: When MR-Rack demos are being viewed or playing, MIDI In is disabled.
+
+ 4. Press Enter to play the demo.
+ 5. Press Enter again to stop the demo.
+ 6. When you're done listening to the demo song, press Exit to return to normal MR-Rack
+
+
+ The Version Number of Your MR-Rack Operating System:
+ You can easily find out what operating system (or O.S.) your MR-Rack is currently using.
+ To Find the Operating System:
+ 1. Press the Save button and hold it down.
+ 2. While still holding the Save button, press the System button.
+ The display briefly shows your current Operating System:
+
+ ENSONIQ MR-RACK
+ O.S. Version: #.##

+
+ ENSONIQ EXP Series Wave Expansion Boards
+ ----------------------------------------
+
+ These are small plug-in boards containing a 256k x8-bit EPROM (27C020) and from 1 to 6
+ SOP44 mask ROMs. These add additional digital sound waves. These can be used with the MR
+ Rack, the full-size MR Keyboards and a few other models.

+
+ To Identify an Installed Expansion Board
+ 1. Press the System button.
+ 2. Turn the Parameter knob until the display shows:
+
+ System parameters:
+ WaveEXP1:xxxxxxxxxxx
+
+ When an Expansion Board is installed, this read-only display will show the name of the
+ Expansion Board located in the first slot.
+
+ 3. Turning the Parameter knob two more times will reveal two more displays which show
+ the names of the Expansion Boards in Wave EXP Slots 2 and 3 (if they're installed).
+ If there are no Expansion Boards installed, the display will show "WaveEXP1= **EMPTY**."
