OVERVIEW

The MicroPiano is a 32-voice MIDI sound module. Designed in a single space, half-rack unit, the MicroPiano is very easy to use. Basically, you select a sound by pressing the Program button, then turning the Data knob at the far right of the module. You can also select the desired EFFECTS, CHANNEL, TRANSPOSE, and TUNING modes by pressing one of their respective buttons on the front panel, and you select the values in each mode with the Data knob. The value you select for each mode is retained until you change it, or turn the power off. The default setting for the Program mode is 1 (Classical Piano). The default setting for EFFECTS is (Prg). Prg designates that each program selected in Program mode has its own default effect associated with it. See the PROGRAM and EFFECTS sections for more details about how programs and effects interact. The default setting for the CHANNEL mode is 1. The default settings for TRANSPOSE and TUNING modes are 0 when you turn on the MicroPiano. Each of these modes is discussed in greater detail in the section entitled, PLAYING YOUR MICROPIANO.
SETTING UP AND CARING FOR YOUR MicroPiano
See the Important Safety and Installation Instructions on the inside front cover for important information as you set up and turn on your MicroPiano. Never take apart your MicroPiano. There are no user-serviceable parts inside. Clean your MicroPiano with a soft, dry cloth. Do not use aerosol sprays on or near the MicroPiano. Mounting Your MicroPiano to a Half-Rack Adapter The MicroPiano is a single-space, half-rack module designed to t securely into any standard 19" equipment rack. For safety, do not turn on the power source for other devices in your MIDI system until the MicroPiano is connected. If you desire to mount the MicroPiano in your current equipment rack, Kurzweil recommends you purchase a standard half-rack adapter from your local dealer. Enclosed with the MicroPiano are four screws and four small adhesive-backed rubber feet for mounting the unit to any half-rack adapter. Attach the rubber feet as shown in the diagram on the next page. The feet are required to be attached to the MicroPiano, whether you mount it in a halfrack adapter or sit it on a table. To mount the MicroPiano to a half-rack adapter, you must use the screws supplied. The four holes in the bottom of the MicroPiano are positioned such that they should line up with at least two mounting holes in most standard adapters. See the illustration on the next page for more mounting information.

Be sure to USE THE SCREWS THAT COME WITH THE UNIT. They are 3/8" in length and intended for use in conjunction with the rubber feet. If these screws are misplaced, do not substitute with screws that are longer than 3/8" in length. If the screws are longer than that, they will hit electronic components within the MicroPiano and very likely damage it.

Connecting Your MicroPiano
Turn the Volume knob on the MicroPiano counter-clockwise until it clicks before plugging in the MicroPiano or other MIDI equipment, to ensure the unit is OFF. Better yet, make sure that your audio system is OFF before hooking anything up.
Look at the back of the MicroPiano. It looks like this:

AC 1.0A

MIDI THRU

LEFT (MONO)

AUDIO OUT RIGHT

MicroPiano Rear Panel

The MIDI IN and MIDI THRU ports work as follows: Plug the MIDI OUT from your keyboard into the MIDI IN port on the MicroPiano, using any standard MIDI cable. If necessary, you can connect the MIDI THRU on the MicroPiano to the MIDI IN port of another device in your MIDI system effects processors or sound modules, etc. Audio Out Left (MONO) and Right connections allow you to hook up the MicroPiano to your amplier or mixer. To get the full signal in mono, plug a cable into the left jack only.

PLAYING YOUR MicroPiano

The front of the MicroPiano looks like this:
Tuning Transpose Channel Effects Program

Power/Volume

MicroPiano Front Panel
Turning On Your MicroPiano The knob furthest to the left controls the MicroPianos ON/OFF function and its volume. Be sure this Volume knob is turned counter-clockwise whenever you turn on your audio system.
After connecting the power, audio, and MIDI cables, turn the MicroPiano on by rotating the Power/Volume knob slightly clockwise until it clicks. Within one second, all of the front panel LEDs and all of the display segments will light briey. The LEDs then turn off, and the display changes to show the software version number. Finally, the Program LED will turn on and the display will show a 1, indicating that the MicroPiano is in PROGRAM mode and is operating normally. Be sure your controller keyboard is transmitting on MIDI Channel 1. You may now begin to send MIDI signals to the MicroPiano and adjust the Volume knob and your audio system to a comfortable listening level. If the MicroPiano fails to operate as just described, refer to the IN CASE OF DIFFICULTY section on page 14. MIDI Indicator When you are sending MIDI signals on the same channel on which the MicroPiano is set to receive, the leftmost decimal point on the LED display will ash, indicating that you are receiving MIDI messages. The DEMO Sequence To hear some of the capabilities of the MicroPiano, try listening to the DEMO sequence. This can be done by selecting CHANNEL mode and turning the Data knob past 16. The display will look like this:

and the DEMO sequence will play.
Program Press the Program button then dial up the desired sound with the Data knob. Pick one and try it out! The default setting for the PROGRAM mode is 1, which corresponds to Classical Piano. You can select from the following sounds:

No Effect Room Bright Room Stage Bright Stage Hall Bright Hall Large Hall Large Bright Hall Chorus Room + Chorus Bright Room + Chorus Stage + Chorus Bright Stage + Chorus Hall + Chorus Bright Hall + Chorus Deep Space Prg (default effect for program)
You may select different effects with the Data knob, if you wish to change the pre-selected effect. Select 0 for No Effect. Any effect you choose other than Prg will remain active when you change programs. Choose Prg to return to a programs default effect. You can also select an effect by sending the MicroPiano a MIDI controller 83 message with one of the values shown in the above chart. Note that any value greater than 16 selects Prg mode. The effects provided with the MicroPiano consist of several types of reverb with and without chorus, as well as the Deep Space effecta unique combination of reverb and echo. Try them out.

Effect Wet/Dry Mix

The default setting for the EFFECTS mode when the MicroPiano is turned on is Prg. Remember, each program has its own predetermined effect, so changing a program when in the PROGRAM mode will change the effect. See pages 6 and 7 or the pull-out charts on pages 17 and 18, for a listing of the MicroPianos programs and effects. The Wet/Dry Mix of reverb can be adjusted from your master controller by sending MIDI controller 91 messages. Values 0-127 change the mix from dry to wet. The Wet/Dry Mix of chorus can be adjusted from your master controller by sending MIDI controller 93 messages. Values 0-127 change the mix from dry to wet. When you change the EFFECTS mode (either through the front panel or through MIDI), the Wet/Dry Mix is reset to the new effects default. Similarly, when you change the PROGRAM mode while the EFFECTS mode is set to Prg, the Wet/Dry Mix is reset to the new effects default. Channel Press the Channel button then turn the Data knob to select the MIDI channel to which your MicroPiano will respond (1 - 16). The default setting for the MIDI Channel is 1 when the MicroPiano is turned on. The MicroPiano responds to one channel at a time. Note: will also appear in this display when you turn the data knob past 16. See page 5 for an explanation of the DEMO sequence. Transpose The MicroPiano can be transposed up or down within a range of 24 semitones ( 2 octaves) by using the Transpose button and then the Data knob. Press the Transpose button and then move the Data knob to the left or the right to control the transposition.

The default setting for TRANSPOSE is 0 when the MicroPiano is turned on. Note: If the MicroPianos transpositions are extreme, certain notes on an 88-key controller (the highest and lowest ones) may be out of range for the MicroPiano and will not sound. Tuning The Tuning button allows you to tune the unit plus or minus 50 cents (one quarter step) in 1 cent increments. This allows you to easily tune with other instruments in your ensemble. Press the Tuning button, then turn the Data knob to select the desired tuning. Turning the Data knob to the left tunes the MicroPiano at, while turning the Data knob to the right tunes the MicroPiano sharp within a range of 50 cents. The default setting for TUNING is 0 when the MicroPiano is turned on. Note: The rst two piano programs are beat tuned, like an acoustic piano. Since the higher harmonics of a stretched string tend to be sharper than those of the real harmonic series, beat tuning ensures that the piano remains in tune with itself harmonically. For this reason, beat tuning is sometimes referred to as solo tuning. The second two programs offer straight tuning, where the fundamental of each note is tuned to A440. This allows for better mixing with other acoustic and electronic instruments. This type of tuning, therefore, is sometimes known as ensemble tuning.
CONFIGURING YOUR MicroPiano
To enter CONFIGURATION mode, press and hold the Tuning button while you turn on your MicroPiano. You will note that the Tuning LED is blinking. You are now in CONFIGURATION mode. To exit CONFIGURATION mode, press the Transpose button.
Link Mode Conguration The MicroPiano can be set to respond to certain MIDI note numbers. This is done by pressing the Channel button and turning the Data knob while in CONFIGURATION mode. If the LED reads , the MicroPiano will respond to ALL notes sent to it. If the unit is set to the unit will only respond to EVEN MIDI note numbers; will only respond to ODD notes. By chaining two MicroPianos together with MIDI THRU and setting one to ODD and the other to EVN, you can have 64-voice polyphony! Note: For reference, Middle C on the MicroPiano is number 60, and notes go up or down from there. The default setting for LINK mode is ALL when the MicroPiano is turned on. Program Change/Enable You can also enable or disable whether the MicroPiano will respond to MIDI program changes. Press Program while in the CONFIGURATION mode, and select either ON or OFF, by turning the Data knob. ON means the MicroPiano will allow program (patch) changes, OFF will not allow program changes. This is useful when there is more than one MIDI device sharing the same MIDI channel and you want to send program changes to other devices, without affecting the MicroPiano, or if your sequencer is sending program changes that you wish to ignore with the MicroPiano. The default setting for PROGRAM CHANGE/ENABLE is ON when the MicroPiano is turned on. After you have congured the MicroPiano, press the Transpose button to return to normal operation.

Velocity Response Curves Many programs in the MicroPiano are designed for a full range of velocity sensitivity. The touch response and MIDI velocity transmission vary with each controller keyboard. With this feature, you can adjust how the MicroPiano responds to different velocity curves sent from particular controllers. To select a curve in CONFIGURATION mode, press the Effects button, then turn the Data knob to choose a curve. You will notice the Effects LED blinking. Several curves are offered for the MicroPiano. Curve 1 is the default setting. The best way to choose the right curve for your controller is to play repeated notes from soft to loud, and listen to the timbre and volume differences as you select different curves. The MicroPiano lets you choose from the following velocity response curves:
MicroPiano Velocity Response Curves
No. Name <no mapping> Easier Harder Hardest Description for controllers that send the full range of velocities on a linear curve for light-velocity keyboards such as the Yamaha SY77 for slightly hot velocity keyboards such as the Roland JV1000 for hot-velocity keyboards such as the Korg 01/W
The MicroPiano uses MIDI (Musical Instrument Digital Interface) to receive input from a keyboard controller and to send messages to other musical instruments. Standard MIDI cables provide the connection between the MIDI ports of one piece of equipment and those of another. To keep things simple, there are only two valid MIDI connections: OUT to IN and THRU to IN. (See the illustration on the next page.)
MIDI IN receives MIDI information from other MIDI equipment. MIDI THRU duplicates the information received by IN and passes it to other equipment.
