16. 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. Hold the Controllers button and
press the ÒGÓ controllers button. Make sure the Switch Type is set to Toggle. Press the
>> button. If the button is not already set to 119 Arp Latch1, assign it to that controller.
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 G 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 G button Off. Change the value of the Latch Mode to Arpeg. Hold some
notes on the keyboard, and turn the button on. Let go of the keys. So far, it works
identically to Overplay mode. Now press 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 G 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 the G 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 G 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 j ack. Make sure that the Switch Type is
set to Momentary. Press the >> button, then 119, then Enter, to set the pedal to Latch 1.
