Chapter 22 ES2 263
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 Bit”-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.
RndN02
RndNO2 (Note On Random2) behaves like Note On Random1 with the exception that it
glides to the new random value using the Glide time (inclusive of modulation). It also
differs from NoteOnRandom1 in that the (random modulation) value changes when
playing legato, while in legato mode.
SideCh
SideCh (Side Chain modulation) uses a Side Chain (tracks, inputs, busses) to create a
modulation signal. The Side Chain source can be selected in the upper gray area of the
window. It is fed to the internal envelope follower, which creates a modulation value
based on the current Side Chain input signal level.
Via—Controlling the Modulation Intensity
Some modulation sources are unipolar, delivering values between 0 and 1. Others are
bipolar, and output values between −−1 and +1. The following sources may be used to
modulate the modulation intensity.
LFO1
The modulation undulates at the speed and waveform of LFO1, which controls the
modulation intensity.
LFO2
The modulation undulates at the speed and waveform of LFO2, which controls the
modulation intensity.
ENV1
ENV1 controls the modulation intensity.
ENV2
ENV2 controls the modulation intensity.
ENV3
ENV3 (the level envelope) controls the modulation intensity.
