C+L (CATCH+LAST)

Sets the MIDI message used to change the parameter with the Matrix Control. Ordinarily, if you wanted to change analogue part parameters using an external MIDI device, you would need to send

System Exclusive messages–MIDI messages designed exclusively for the JD-XA. However, System Exclusive messages tend to be complicated, and the amount of data that needs to be transmitted can

get quite large. For that reason, a number of the more typical of the JD-XA’s analog part parameters have been designed so they accept

the use of Control Change (or other) MIDI messages for the purpose of making changes in their values. This provides you with a variety of means of changing the way tones are played. For example, you can use the Pitch Bend lever to change the LFO cycle rate, or use the keyboard’s touch to open and close a lter.

The function which allows you use MIDI messages to make these changes in realtime to the tone parameters is called the

“Matrix Control.”

Up to four Matrix Controls can be used in a single part. To use the Matrix Control, specify which MIDI message (Source) will be used to control which parameter (Dest) and how

greatly (Sens).

* Velocity and Keyfollow correspond to Note messages.

* If you want to use common controllers for the entire JD-XA, select “SYS1”–“SYS4.” MIDI messages used as System

Control 1–4 are set with the Tone Control 1–4 Src (Owner’s Manual “Overall Settings for the JD-XA” (p. 12) 0

“CONTROL” 0 “Sys Ctrl1–4”).

OFF Matrix Control will not be used.

VELOCITY Velocity (pressure you press a key with)

KEYFOLLOW Keyfollow (keyboard position with C4 as 0)

TEMPO Tempo specied by the tempo assign source, or the tempo of an external MIDI sequencer

Explanation

When portamento is used, this species the time over which the pitch will change. Higher settings will cause the pitch change to the next note to take more time.

Applies legato. The term “legato” refers to a playing style in which notes are smoothly connected to create a owing feel. This creates a smooth transition between notes, which is eective when you wish to simulate the hammering-on and pulling-o techniques used by a guitarist.

* This is available only if poly stack is “o .”

This layers a single sound. If the Unison Switch is on, the number of notes layered on one key will change according to the number of keys you play.

* This is available only if poly stack is “on.”

Species the amount of pitch change that occurs when the pitch bend/modulation lever is moved all the way to the left.

Species the amount of pitch change that occurs when the pitch bend/modulation lever is moved all the way to the right.

The pitch lever aects only the last-sounded note. If you play a note while the pitch bend lever is already moved, that note sounds at its normal pitch (as though the lever were in the center). The pitch starts changing only after the lever passes through the center position.

A 4-pole lter of a circuit design often used by Roland, providing relatively standard operation.

A ladder lter using transistors, providing a strong character.

This is a multi-mode lter consisting of a simultaneous LPF, HPF, and BPF. Although it is a relatively standard circuit, it is designed so that the resonance changes dramatically.

Here’s how you can make the lter cuto frequency to vary according to the key you play. If the knob is turned toward the right, the cuto rises as you play higher notes. If the knob is turned toward the left, the cuto falls as you play higher notes.

When portamento is used, this species the time over which the pitch will change. Higher values lengthen the time over which the pitch will change to the next note.

Portamento will be applied only when you play legato (i.e., when you press the next key before releasing the previous key).

Turns ring modulator on/o. By multiplying partial 1’s OSC and partial 2’s OSC, this creates a complex, metallic-sounding

waveform like that of a bell. The partial 1’s OSC waveform will change as shown in the illustration, and partial 2’s OSC will be

output with its original waveform. Setting the partial 1 OSC and the partial 2 OSC to dierent pitches will make the ring modulator

If Ring Switch is turned “ON,” the PWM Depth, PW, and S-Saw Detune of partial 1 and partial 2 cannot be used.

In addition, if an asymmetrical square wave is selected as the OSC waveform, the OSC variation will be ignored, and there will be a slight dierence in sound compared to the originally selected waveform.

Species whether notes will sound polyphonically (POLY) or monophonically (MONO).

This is valid only if the Mono/Poly parameter is set to “MONO.” If this is “ON,” pressing a key while the previous key remains held down will cause the pitch to

change to that of the newly pressed key while maintaining the state in which the previous note was being sounded. This creates a smooth transition between notes, which is eective when you wish to simulate the hammering-on and pulling-o techniques used by a guitarist.

This layers a single sound.

If the Unison Switch is “ON,” the number of notes layered on one key will change according to the number of keys you play.

Explanation

Species the depth of 1/f modulation that is to be applied to the tone (1/f modulation is a pleasant and naturally-occurring ratio of modulation that occurs in a babbling brook or rustling wind.).

Species the amount of pitch change that occurs when the pitch bend/modulation lever is moved all the way to the right.

NORMAL The pitch bend lever works in the conventional way.

The pitch lever aects only the last-sounded note. If you play a note while the pitch bend lever is

C+L

(CATCH+LAST)

already moved, that note sounds at its normal pitch (as though the lever were in the center).

The pitch starts changing only after the lever passes through the center position.

Shortens the FILTER and AMP Attack Time according to the spacing between note-on events.

0–127

Higher values produce a greater eect. With a setting of 0, there will be no eect.

This is eective when you want to play rapid notes using a sound that has a slow attack (Attack Time).

Shortens the FILTER and AMP Release Time if the interval between one note-on and the next note-

0–127

o is brief. Higher values produce a greater eect. With a setting of 0, there will be no eect.

This is eective when you want to play staccato notes using a sound that has a slow release.

Explanation

Use this parameter to select from among the 29 available total eect. For details on total eect parameters, refer to “TFX Parameters” (p. 19).

Globally controls the selected total eect. Global control means to control multiple parameters simultaneously.

Species whether total eect will be used (ON) or not used (OFF).

Edit the parameters for the selected TFX type.

If you turn Limit Mode on, the eect depth is restricted to prevent feedback or an extremely high volume.

Parameters that are aected by Limit Mode are indicated by a

symbol (p. 19). This can be

convenient when you’re performing in high-volume conditions at a club or hall.

* This parameter is not shown for types that have no parameters marked by

Simultaneously adjusts the input and output gain of the total eect. This is convenient when adjusting dynamics-type eects (such as overdrive or compressor) that

produce their eect by varying the volume. For some eects, it may be dicult to notice the result of this adjustment.

The cycle of the Timing Pattern is based on a 4/4 time signature. You can use Rate to adjust the synchronization speed as follows. Rate maximum: One cycle of Timing Pattern corresponds to one measure. Rate minimum: One cycle of Timing Pattern corresponds to a 32nd note. By changing the Rate setting you can change the cycle in the range between a 32nd note to one full measure.

*3: Set Balance to the center value, adjust PITCH to raise the frequency of the sine wave, and set Threshold so that the sine wave is heard appropriately for the input source. After you’ve nished setting the Threshold, adjust the Pitch and Balance. This is a useful way to strengthen a kick drum.
