Chapter 21 ES2 281

The modulation wheel and aftertouch serve as modulation sources.
MIDI Controllers A–F
MIDI controllers available in the mod matrix are named Ctrl A–F and can be assigned to
arbitrary controller numbers (via the MIDI Controllers Assignment menus at the bottom
of the ES2 interface).
Note: Earlier ES2 versions offered the Expression, Breath, and MIDI Control Change
Messages 16 to 19 as modulation sources. These MIDI controllers are the default values
for the assignment and guarantee backwards compatibility.
The values of the MIDI Controllers Assignment menus are only updated if the default
setting is loaded, or if a setting that was saved with a project is loaded. If you simply
step through settings, the assignment will remain unchanged.
The MIDI Controllers Assignment menus allow you to assign your favorite MIDI
controllers as Ctrl A, Ctrl B, and so on.
All MIDI Controller Assignment menus feature a Learn option. If this is selected, the
parameter will automatically be assigned by the first appropriate incoming MIDI data
message. The Learn mode features a 20 second time-out facility: If the ES2 does not
receive a MIDI message within 20 seconds, the parameter will revert to its original MIDI
controller assignment.
Note: If none of the controller assignments (Ctrl A–F) is assigned to Expression, the
Expression CC message (Ctrl #11) controls the output volume.
Note: The Vector Stick (Joystick) of the Korg Wavestation synthesizer generates
Controllers 16 and 17, for example. If you use this instrument as your master keyboard,
you can control any two ES2 parameters directly with its Joystick.
Note: In the MIDI specification, for all controllers from 0 to 31, there also is a LSB-
Controller defined (32 to 63). This Least Significant Byte-controller allows for a
resolution of 14 bit instead of 7 bit. The ES2 recognizes these control change messages
correctly; the breath or expression controllers, for example.
RndN01
RndNO1 (Note On Random1) outputs a random modulation value between –1.0 and 1.0
(same range as an LFO), that changes when a note is triggered or re-triggered. The
(random) note-on modulation remains constant throughout the duration of the note
until the next note-on trigger.
Note: There is no value change when playing legato, while in legato mode.
