Frequently Asked Questions - P150 KAWAI

How do I change the temperament on my Kawai P150?

To change the temperament, hold down the appropriate Tone Selector switch while turning on the power. For example, press and hold PIANO 1 for equal temperament without tuning curve, or choose another switch for historical temperaments like Mersenne, Pythagorean, etc.

How do I connect external MIDI devices?

Use the MIDI IN, OUT, and THRU jacks on the rear panel. Connect MIDI OUT from the P150 to MIDI IN on another device to send performance data. Ensure both devices are set to the same MIDI channel.

How does the transpose function work?

The TRANSPOSE slider shifts the keyboard pitch. Moving it to the right raises the key (e.g., C to C#), and to the left lowers it. This lets you play in one key while hearing a different key.

How do I activate the Chorus effect?

Press the CHORUS effect switch to cause the output to swell outward. Note that on the P150, only Chorus is available (no Tremolo). The effect may not work on some tone colors like STRING ENSEMBLE or BRASS ENSEMBLE on the P250, but for P150, it works on most.

Can I tune the Kawai P150?

Yes. Enter programming mode (hold CHORUS and press PIANO 1, PIANO 2, E. PIANO 1 simultaneously), then press E. PIANO 2 until it flashes. Use the highest white key to raise pitch or highest black key to lower it. To exit, press CHORUS again.

What tone colors are available on the P150?

The P150 includes eight tone colors: PIANO 1, PIANO 2, E. PIANO 1, E. PIANO 2, HARPSICHORD, VIBRAPHONE, FULL ORGAN, and BRASS.

How do I connect external speakers or amplifiers?

Use the LINE OUT jacks (L(MONO)/R) on the rear panel. Set the adjacent output level switch to H (high) or L (low) to match the input impedance of the connected equipment.

How should I clean and maintain the digital piano?

Clean the exterior with a soft, dry cloth. Avoid using liquids or cleaners. Keep the piano away from direct sunlight, moisture, and sources of electrical noise like fluorescent lights.

What is the 'NEXT' function?

The NEXT function allows a smooth tone change. When you press a tone selector while keys or the damper pedal are held, the LED flashes to indicate readiness. Once you release all keys and pedal, the new tone engages seamlessly.

How do I set the MIDI channel?

Enter programming mode (hold CHORUS and press PIANO 1, PIANO 2, E. PIANO 1). Then press PIANO 2 to enter channel setting mode. Press one of the first 16 white keys to select the desired channel (1-16). The channel is set for both send and receive.

Alone, its wooden keys provide the touch response and full dynamic range required for a superb performance on the piano, harpsichord, organ, and other instruments available. Connected to the MIDI interface, a set of terminals conforming with an international standard, it allows you to play other electronic instruments at the same time — opening a whole new world of musical possibilities.

This Owner's Manual contains valuable information that will help you make full use of this instrument's many capabilities. Read it carefully and keep it handy for future reference.

IMPORTANT NOTES

- Power Supply

Use only the voltage appearing on the plate next to the power cord at the rear of the instrument. One that is too high represents a shock hazard and will also damage the instrument's delicate electronic circuitry.

- Electrical Noise

Keep the instrument away from electrical motors, neon signs, fluorescent light fixtures, and other sources of electrical noise.

- Power Cord

Do not touch the power plug with wet hands. There is a risk of electrical shock.

Treat the power cord with care as well. Stepping on or tripping over it can break or short-circuit the wire inside.

• Repairs and Alterations

Never attempt to remove or modify the piano's circuitry. There is a significant shock hazard. If you think something is broken, consult your nearest authorized Kawai dealer.

- After Use

Always turn the power off when the instrument is not in use. Leaving the piano energized for extended periods can lead to serious problems.

2 VOLUME

The instrument's output level increases as the slider moves to the right.

3 TRANSPOSE

Shifting the slider to the right raises the piano's key (C→ C^#→ D→ E^b→ E→ F) ; shifting it to the left lowers the key (C→ B→ B^b→ A→ A^b→ G→ F^#) . You can therefore play the music as written - in C major, for example - and have the instrument transpose the output to a higher or lower key to match your voice.

1 PEDAL

These jacks accept cables from damper and soft pedals.

2 MIDI

These terminals enable properly equipped electronic instruments to communicate through the internationally recognized MIDI interface.

IN - Accepts MIDI data from other instruments.

OUT - Transmits MIDI data from the instrument to others.

THRU – Retransmits all incoming MIDI data.

4 TONE SELECTORS

There is a wide selection of piano, organ, harpsichord, and other tone colors available.

5 EFFECTS

These functions cause the output to swell outward (CHORUS) or fluctuate (TREMOLO).

Note: TREMOLO is only available on the model 250.

3 LINE IN

These jacks connect two channels of output from other electronic instruments to the piano's speaker.

Note: This output bypasses the piano's VOLUME control. To adjust the balance, you must use the output volume controls on the individual instruments.

4 LINE OUT

These jacks provide two channels of output for amplifiers, stereo systems, tape recorders, or similar equipment. The two-position switch to the right allows you to adjust the output level to High (H) or Low (L) to match the input impedance of the other equipment.

Basic Operation

1 Basic Operation

1 Turn on the power.

When the power is first applied, the LED next to the PIANO 1 switch in the tone selector section lights.

POWER

2 Adjust the volume.

Sound a note on the keyboard and adjust the volume. (Moving the slider to the right raises the volume; leftward motion lowers it).

3 Choose a tone color.

The piano uses one tone color at a time. Tone selector switches cannot be pressed simultaneously.

4 Play.

Experiment with the various tone colors to acquaint yourself with what is available.

5 (Optional) Add an effect!

Press an effect switch to cause the output to swell outward (CHORUS) or fluctuate (TREMOLO).

Note: TREMOLO is only available on the model 250. The way the effect acts on the tone color varies with organ-type sources and other sources. TREMOLO and CHORUS do not work on STRING ENSEMBLE or BRASS ENSEMBLE on the Model 250.

2 The NEXT Function

Pressing a tone selector switch does not necessarily produce an immediate change. If you are pressing any keys on the keyboard or holding down the damper pedal, the LED next to the switch will start flashing to indicate that the piano is ready to change. When you release all keys and the damper pedal, the tone color will instantly change and the LED will light steadily. By specifying in advance, you will therefore be able to make a smooth, natural transition without removing your hands from the keyboard.

Temperaments

Your Kawai digital piano offers not only equal temperament, the modern standard, but also immediate access to those popular during the Renaissance and Baroque period.

■ Procedure

Normally, when the power is first applied, the piano assumes the standard: equal temperament corrected according to the tuning curve. To change to a different temperament, apply the power while holding down the appropriate TONE SELECTOR switch:

PIANO 1 = Equal temperament without the tuning curve.

This, by far the most popular piano temperament, divides the scale into twelve equal semitones and has the advantage of producing the same chords for all transpositions.

- Mersenne pure temperament

This temperament, which eliminates consonances for thirds and fifths, is still popular for choral music.

● Pythagorean temperament

This temperament, which uses mathematical ratios to eliminate consonances for fifths, has problems with chords, but produces a very beautiful melodic line.

- Meantone temperament

This temperament, which uses a mean between a major and minor whole tone to eliminate consonances for thirds, was devised to eliminate the lack of consonance experienced with certain fifths for the Mersenne pure temperament. It produces chords that are more beautiful than those with the equal temperament.

- Werckmeister III temperament, Kirnberger III temperament

For keys with few key signatures, this temperament produces the beautiful chords of the mean tone, but, as the signatures increase, the tension increases, and the temperament produces the beautiful melodies of the Pythagorean temperament. It is used primarily for classical music written to take advantage of these characteristics.

■MIDI Interface and Tuning

1 Introduction

The letters MIDI stand for Musical Instrument Digital Interface, an international standard for connecting synthesizers, drum machines, and other electronic musical instruments so that they can exchange performance data. The Model 250/150 features three terminals — IN, OUT, and THRU — that allow it to both send and receive these kinds of data.

Note: The sending and receiving instruments must be assigned the same channel number before they can communicate.

2 Typical Applications

2.1 Ensemble playing with another keyboard instrument

Example: a Kawai K3 digital synthesizer

If you connect the MIDI OUT terminal on your electronic piano to the MIDI IN terminal on the synthesizer and the synthesizer's OUTPUT terminal to the piano's LINE IN terminal, you will be able to play both simultaneously from the piano keyboard. The interface transmits both the keys played and the strength with which you played them, so the synthesizer output is exactly the same as it would be if you were playing the keyboard directly. The only differences is that the synthesizer uses a different tone color, which blends with the digital piano's to create an ensemble effect. You can, for example, add the synthesizer's strings to your piano solo to give it more depth.

Note: If you reverse the MIDI IN and MIDI OUT connections, you can play the piano from the synthesizer just as easily.

2.2 Drum Machines

Example: a Kawai R-100 drum machine

Changing to a drum machine allows you to add a rhythm accompaniment to your playing or create special effects by adding notes from the percussion instrument to the piano output.

2.3 Sound Generator Modules

Example: a Kawai K3m synthesizer module

Connecting your piano to a Kawai K3m allows you to not only play the ensembles discussed in the first example above, but also split the keyboard into two sections, each of which uses a separate source. The illustration shows a piano-bass combination.

Note: You must set the LOCAL CONTROL parameter (described on a later page in this section) to OFF to use the split feature.

3 MIDI Implementation

The MIDI interface on your Kawai Electronic Piano allows you to:

(1) Receive and transmit keyboard data.
(2) Receive and transmit soft and damper pedal data (ON/OFF).
(3) Receive and transmit program numbers — codes for changing tone colors.
(4) Set MIDI channel numbers for sending and receiving to any number between 1 and 16.
(5) Turn LOCAL CONTROL on and off - either from the keyboard or another instrument.

4 Operation

To issue commands to the MIDI interface or use the tuning capability, you must first switch the piano to a special "programming" mode.

4.1 Entering the programming mode

Hold down the CHORUS switch and simultaneously press the first three tone selector switches (PIANO 1, PIANO 2, and E PIANO 1). The LEDs next to the CHORUS and PIANO 1 switches should then start flashing to indicate that the piano is in the programming mode. In this mode, striking the keyboard produces no output.

4.2 Sending a program number (tone color code)

In the programming mode, the flashing LED next to the PIANO 1 switch indicates that the interface is ready to transmit a program number. Select the program number by pressing the corresponding pair of black keys at the lower end of the keyboard. There are a total of 128 numbers possible: the first thirteen black keys give the first and second digits ("00" - "12") of this three-digit number; the next ten, the final digit ("0" - "9").

Note: You must press the two keys in order from left to right. Alternatively, you can press just the second one to change only the third digit.

• Examples:
  

(The examples above are procedures for the Model 150; however, they are applicable to the model 250 as well. Use the black keys starting from the left end.)

4.3 Setting the channel

With the piano in the programming mode, press the PIANO 2 switch so that it flashes to indicate that the interface is waiting for a channel specification.

Select the channel by pressing the one of the first 16 white keys at the lower end of the keyboard.

Note: You have 16 channels to choose from.
Channel No.

Pressing one of these keys automatically sets the instrument's sending and receiving channel to the number selected.

Note: When the power is first applied, the interface uses Channel 1 and has the OMNI parameter on. Changing to another channel automatically turns the OMNI parameter off.

4.4 Turning LOCAL CONTROL on and off

LOCAL CONTROL refers to the connection between the sound source and the keyboard. It is normally on. Turning it off turns off the keyboard; the instrument sounds only when it receives keyboard data through the MIDI interface.

■ Procedure

With the piano in the programming mode, press the E PIANO 1 switch so that it flashes to indicate that the interface is waiting for a LOCAL CONTROL specification. Press the highest black key to turn it off, the highest white one to turn it on.

Note: Momentarily turning off the power also turns LOCAL CONTROL on.

4.5 Tuning

With the piano in the programming mode, press the E PIANO 2 switch so that it flashes to indicate that the piano is ready to be tuned. Unlike the other functions in the programming mode, this one produces keyboard output so that you can compare the piano's pitch with another instrument. It uses the same keys as the LOCAL CONTROL function: Press the highest black key to lower the pitch, the highest white one to raise it.

Note: Momentarily turning off the power restores the original pitch.

4.6 Leaving the programming mode

To leave the programming mode, simply press the CHORUS switch. The flashing will stop, and you will return to the tone color in effect when you entered the programming mode.
