Emax II operation manual

Note: If the filter and VCA release are both at 32 (also see
DYNAMIC PROCESSING 12
),
a key will sustain at the sustain level even after you take your fingers off the keys. This
is like the HOLD function found on some synthesizers.

LFO SETUP
(RATE, DELAY, VARIATION)
A Low Frequency Oscillator, or LFO, is simply a wave repeats at a slow rate. The Emax
II contains a triangle wave LFO for each of its 16 channels. The triangle wave is very
useful because it provides realistic vibrato and tremolo effects.
The LFO setup function sets three LFO parameters (initial rate, delay before onset of LFO
modulation, and LFO variation).
Application:
After pressing a key(s), LFO delay delays the onset of vibrato by an
adjustable amount. This simulates an effect often used by string players, where the
vibrato is brought in only after the initial note pitch has been clearly established.
Application:
LFO variation adds a randomized quality to ensemble sounds by provid-
ing slightly different vibrato rates for each key being held down. This can make
orchestral voices sound truly polyphonic.
1. Activate
DYNAMIC PROCESSING 15
. The display will say:
Rate Delay Vari
XXX XX XX
2. Select the desired parameter for adjustment with the cursor buttons, then use the data
slider to change the parameter value. These are the available parameters:
■
LFO Rate:
Varies from 1 to 120; higher values give a faster modulation rate.
■
LFO Delay:
Sets the amount of time between hitting a key and the onset of modulation.
Range is from 00 to 99, with higher values giving longer delays.
■
LFO Variation:
In addition to having true, one-LFO-per-voice polyphonic modula-
tion, the Emax II also has a great feature called variation. With 00 variation, each key will
have the same vibrato rate. Increasing variation (to a maximum of 15) alters the LFO rate
every time you hit a key; the higher the number, the greater the variation in LFO
frequency. For effects such as ensemble playing, the variation feature is invaluable as it
creates the illusion of multiple players, each having their own vibrato rate.
