20. Using the Various Arpeggiator Latch Modes

The Latch Mode parameter allows you great variation in deciding which notes that you

play should be used (latched) by the arpeggiator. In the previous tutorial, Latch Mode

was set to Keys, so that the arpeggiator simply latched any note you pressed and held it

only as long as the key was held down. But there are many other possibilities.

1. Start with the Setup you created in the last tutorial. If it is not already on, press the

SW2 button to turn the arpeggiator on. Hold the Controllers button and press the SW3

controllers button. Press << to get to Switch Type and set it to Toggle. Press the >>

button. Set the On Ctl to 119 Arp Latch1. Press the >> button and set the On Value to

64. Press the >> button twice and set the Off Value to 0. Make sure the button is turned

Off (the button itself is not lit).

2. Press the Arpeggiator button. Press the >> button 4 times to get to the Latch Mode

parameter. Change the value to Overplay. Play some notes on the keyboard. Notice they

do not arpeggiate. Now hold some notes and press the SW3 button. The notes start

arpeggiating. Let go of the keys. They still continue to arpeggiate. Play some more notes.

Notice they are not added to the arpeggio. When you use Overplay mode, only the notes

held when the switch is turned on will be arpeggiated.

3. Turn the SW3 button Off. Change the value of the Latch Mode to Arpeg. Hold some

notes on the keyboard, and turn the SW3 button on. Let go of the keys. So far, it works

identically to Overplay mode. Now press and hold another key. Notice that the note is

added to the arpeggio. Let go of the key. The new note is removed from the arpeggio, but

the other notes continue to play.

4. Turn the SW3 button Off. Change the value of the Latch Mode to Add. Hold some

notes on the keyboard, and turn the button on. Let go of the keys. Again, so far it works

identically to Overplay mode. Now press another key. As with Arpeg mode, the note is

added to the arpeggio. Let go of the key. Notice that it continues to be arpeggiated. You

can keep striking keys and they will keep being added.

Note that with Arpeg and Add modes, you donÕt have to be holding any notes when

you turn on theSW3 button. You can turn it on and then play notes and they will start

arpeggiating. But if you then let go of the notes, they will stop playing in Arpeg mode but

keep playing in Add mode (since you played the keys after turning on the Latch).

5. Turn the SW3 button Off. Change the value of Latch Mode to Auto. The previous 3

modes all used controller 119 to latch the notes for the arpeggiator. Auto does not use

controller 119. Play a chord. The notes arpeggiate. Press another key. The note gets

added to the arpeggio. Let go of the key. Notice that the note is still part of the arpeggio.

In fact you can let go of all keys but one, and every key that you pressed will still be part

of the arpeggio. That is the difference between Auto and Keys (our original Latch mode).

With Keys, once you let go of the key, the note is removed from the arpeggio. But with

auto you can keep striking as many keys as you want to keep adding notes, and as long

as you hold one note, you will hear all of the arpeggiated.

6. Finally, change the value of Latch Mode to Pedals. Hold the Controllers button and

press the pedal connected to the Switch Pedal 1 jack. Press the << button and make
