SONG RECORDING

The Song Recorder built into the piano can record two individual tracks, allowing you to record one part and then record a second, complementary part while the first part is played back.

To Record a Track

• Press the [SONG] button and the [METRONOME] button simultaneously to enter Record Wait Mode. The Song button’s LED will light, and the Metronome will begin playing at the currently selected tempo.
• The LED display will show: REC for one second, after which it will show: TR1.

• The piano is now in Record Wait Mode. To start recording, begin playing the keyboard. Recording starts automatically as soon as you start playing.

NOTE: When Record Wait Mode is active, you can also start recording by pressing the Song button. In that case, the Song Recorder will record silence until you start playing the keyboard.

• To end recording, press the [SONG] button.

• Repeat to record track 2. Recording will begin when the first key is pressed.

• As mentioned at the beginning of this section, you can record to two independent tracks within each song you record. This means that you can make a recording, and after you’re done, play back what you recorded while recording a complementary part on a second track. The Allegro automates some of the track selections to make the Song Recorder
  more intuitive:

• When you start recording, if data has already been recorded on track 1, the LED display will show: TR2, and the Song Recorder will record on this track.

• During recording, any notes already recorded on the other track will be played back. If you are recording on track 2, anything previously recorded on track 1 will be played back for you.

• If tracks 1 and 2 both contain data, this piano will automatically choose to record to the track that was NOT last recorded to. (If your last recording was on track 1, track 2 will be selected; if your last recording was on track 2, track 1 will be selected.)

To Manually Select a Track to Record to:

• Press the [SONG] button and the [METRONOME] button simultaneously to enter Record Wait Mode.

• Turn the [DATA CONTROL] knob to select between track 1 and track 2.

• If either of the tracks contains recorded data, the display will show a dot “.” in the bottom right hand corner: TR1, TR2.

• You will also see options for Clear (abbreviated CLR) and Cancel (abbreviated CAN ), which you can ignore for the moment. These will be discussed later in this section.

• When the LED display shows the track you wish to record to, you may begin playing whenever you are ready, and recording will automatically begin as soon as you play the first note.

To Cancel Recording While in Record Wait Mode:

• Turn the [DATA CONTROL] knob until the LED display shows: CAN.

• Press the [SONG] button.

• Record Wait Mode will exit, and the keyboard will be back in Performance Mode, with no changes to the contents of either track 1 or track 2.

To Erase a Single Track in the Song Recorder:

• Press the [SONG] button and the [METRONOME] button at the same time to enter Song Recording Mode.

• Use the [DATA CONTROL] knob to select the track you wish to erase.

• Press the [SONG] button twice.

• The track will be erased, and this piano will be back in Performance Mode.

To Change Metronome Tempo While in Record Wait Mode:
The metronome tempo can be adjusted while in Record Wait Mode by pressing and holding the [METRONOME] button and using the [DATA CONTROL] knob to select the desired value. However, the metronome tempo can not be adjusted during recording.

To Turn Off the Metronome While Recording:
Press the [METRONOME] button, and the metronome will stop while recording continues. Pressing the [METRONOME] button again will turn the metronome on again. Note that the metronome can also be turned on and off in the same way while in Record Wait Mode, before recording commences.

To Clear all Data in the Song Recorder:

• Press the [SONG] button and the [METRONOME] button at the same time to enter Song Recording Mode. This will start the Metronome and place the Song Recorder in Record Wait.

• Turn the [DATA CONTROL] knob until the LED displays: CLR.

• Begin playing the keyboard. All previously recorded data on tracks 1 and 2 will be cleared, and the notes you are now playing will be recorded on track 1.

• To clear all data on tracks 1 and 2 without recording anything new, after step 2, press the Song button twice.

• You will then be back in Performance Mode, with all data cleared from the Song Recorder.
  NOTE: the Clear function always erases recorded notes from both tracks. For instructions on how to erase data from only one of the two tracks, please read the earlier section, To Erase a Single Track
  in the Song Recorder.

To Play Back Your Song Recorder Tracks:

• From Performance Mode, press the [SONG] button to enter Song Play Mode.

• Use the [DATA CONTROL] knob to select one of the following:

  • SNG: Playback of both of the Song Recorder tracks simultaneously.
  • TR1: Playback of Song Recorder track 1. TR2: Playback of Song Recorder track 2.
  • Press the [SONG] button to start playback.
  • While the Song is playing, the LED display will show: PLY.

NOTE: If there is nothing recorded on either of the tracks (1 or 2), then the Song will not play. Rather, the Song LED will flash 3 times quickly, and the piano will exit Song Play Mode and resume Performance Mode, with the LED display showing the currently selected voice.

To Stop Playback and Exit Song Play Mode:
Press the Song button. Song playback will stop, and the piano will exit Song Play Mode and resume Performance Mode with the LED display showing the currently selected voice.

EDIT FUNCTIONS

In Edit Mode, the function of the [DATA CONTROL] knob is changed to specify a number of different values. The [DATA CONTROL] knob will “time out” after 10 seconds and return to default metronome tempo.
Keyboard control keys are used to select the function upon which the [DATA CONTROL] knob will have an effect.

Use of Function Key
Please refer to the appropriate sections earlier in this manual for proper use of the [DATA CONTROL] knob when editing the Metronome, Layer, Split, Transpose and Octave functions of the Allegro.

Master Tuning
The Allegro is tuned to A440 when the power is turned on and does not require tuning. However, if desired, in order to play along with other instruments or recordings that are tuned differently, the tuning may be adjusted in semitone increments from -64 to +63 (One full tone).
To change the Master Tuning:

• Press the [FUNCTION] key to enter Edit Mode
• Press the F#2 key to select the [DATA CONTROL] knob to the Master Tuning Function. The LED will show: TUN.
• Turn the [DATA CONTROL] knob to the desired value (-64 – 63).
  NOTE: Master tuning must always be manually adjusted back to -0-.

Touch (Sensitivity)
The Touch Select function allows the choice of 4 sensitivity settings or velocity curves which determine how the force with which you hit the keys affects the volume of the notes played. This piano provides you with four different keyboard sensitivity options:

• Normal (A,3 key): This is the default setting and should work well for most players who play with an average amount of force. When selected, the LED display shows: NOR.

• Low (F#3 key): This setting generates lower
  velocity values for the same force and is useful for playing more quietly, even with a heavy touch. When selected, the LED display shows: LO.

• High (B,3 key): The high setting generates higher velocity values for the same force and is useful for playing more loudly, even with a light touch. When selected, the LED shows: HI.

• Fixed (F3 key): This setting effectively disables sensitivity control. The keyboard will generate a fixed velocity value of 100 (on a scale of 0-127) regardless of how hard or soft you play. When selected, the LED display shows: FO.

To Set the Keyboard Sensitivity:

• Depress the [FUNCTION] button to enter Edit Mode. Press the desired Touch Select key (Ab3, F#3, Bb3, F3). The LED display will show the selected touch setting.

• Key locations are illustrated in a larger format in Appendix B: Advanced Functions Keyboard
  Chart (pg. 28)

MIDI FUNCTIONS

• The Musical Instrument Digital Interface (MIDI) is an industry-standard protocol that enables electronic musical instruments such as keyboards, computers, drum machines, etc. to communicate, control, and synchronize with each other. MIDI transmissions consist of electronic codes that communicate notes to be played, the instrument, pitch or intensity that notes are to be played with, and controlling codes such as volume, vibrato, cues and clock signals.
• The Allegro has several functions that facilitate its use as a MIDI device or controller.

MIDI Connections

Connect the Allegro to other MIDI-capable devices as required.

MIDI Channels
The MIDI system in the Allegro has 16 channels numbered from 1-16. Each of the channels is responsible for a voice. When the instrument receives MIDI information from an external device, the active channel is determined by the control message.
The transmission channels are fixed as follows:

Multitimbral Mode
The Allegro is able to receive MIDI information on up to 16 channels simultaneously. If you plan to use your piano with a multitrack MIDI recording system, you can record up to 16 different parts using the Williams Allegro voices, each played back individually on different MIDI channels. To ensure your recorded part is played back with the correct voice make sure to press the voice button first and play your part second.
NOTE: Because the Allegro is receiving playback information via MIDI, the currently selected voice on the piano may not correspond to the voice being played back.

Local On/Off
Turning the Local On/Off function to “Off” will disconnect the keyboard from the internal sound engine of the piano. The Allegro may then be used as a MIDI controller to control other MIDI devices or virtual instrument software running on a computer, without playing the sounds on the piano. Addition-ally, it may be desirable to turn local playing off for other requirements such as when using MIDI sequencing software on your computer.

Turn Local On/Off to Off

• Press the [FUNCTION] key to enter Edit Mode
• Press the Local On/Off key (C#3). The LED display will show: OFF.

Turn Local On/Off to On
Repeat the above procedure. The LED display will show: ON.

Main MIDI Transmit Channel (C#2)
The main MIDI transmit channel number may be changed as necessary by increasing or decreasing the channel number.

Change the Main MIDI Transmit Channel

• Press the [FUNCTION] button to enter Edit Mode.
• Press the MIDI Transmit Channel Key (C#2) to set the [DATA CONTROL] knob to increase or decrease the Main MIDI Transmit channel number. The LED Display will momentarily show: CHA.
• Use the [DATA CONTROL] knob to select the desired Main MIDI Transmit Channel.

NOTE: The MIDI channels used for the Split and Layer voices are relative to the Main MIDI Transmit Channel, in the following ways:

Split Voice Transmit Channel:
Main MIDI Transmit Channel +1

Layer Voice Transmit Channel:
Main MIDI Transmit Channel +2

Numeric Data Entry Keys
(G5,A5,B5,C6,E6,F6,G6,A6,B6)

• Several of the advanced MIDI editing functions of this piano require that a numeric value be entered. This may be accomplished using the Numeric Data Entry Keys.
• Functions requiring numeric input include:
  • Program Change
  • Bank MSB
  • Bank LSB
  • [DATA CONTROL] Assign
• These features are discussed below.

NOTE: If preferred, the [DATA CONTROL] knob may also be used to scroll to the desired numeric value, instead of using the Numeric Data Entry Keys.

Enter Key (C7)
When entering data in Edit Mode, pressing the Enter key will cause the selected data to be sent to this piano as a MIDI command. After pressing the Enter key, the Allegro will return to Performance Mode.

Cancel Key (B6)
