Using Key Switches
In some cases, it is useful to switch to a particular layer, regardless of the current
position in the Alternation list. To make this possible, you can specify a key switch per
layer. As soon as the key switch note is played, the alternation list jumps to the
corresponding layer. The alternation then continues from that position.
• To set the key switch, type in the note, as text or number, in the key switch column
of the Alternation List.
Alternation Mode
The process of alternating between layers is determined by the following options:
Mode
Cycle Up
Cycle Down
Random
Exclusive Random
Per Key
Select this option to apply the alternation for each MIDI key separately. When this is
switched off, the alternation is applied globally across the whole keyboard, so that any
key you play advances the alternation sequence.
Enable
Here, you can specify the MIDI key that starts and stops the alternation sequence.
This key will be used exclusively for this function and will not trigger any notes.
When set to Off, playback remains on the selected layer.
Previous/Next
Here, you can specify the MIDI key that switches to the previous/next expression.
Reset
Here, you can specify the MIDI key that resets the Alternation sequence.
Grace Time
The Grace Time parameter sets a minimum time between two steps, which allows you
to play chords, for example. Otherwise, each note of the chord will play with a different
layer.
Description
