MODULATION CONTROLS (CONTINUED)
HI RANGE
When engaged, the rate of the LFO is increased by 10x. In this mode, the LFO range is from 1Hz (one
cycle per second) through 1,000Hz (1,000 cycles per second).
NOTE: No matter which range you choose, modulation at normal vibrato rates (between 5 and 10Hz) is possible.
SYNC
When the SYNC button is illuminated, the LFO rate is synchronized to the Sub 37’s internal clock, or
external MIDI clock. In this mode, the LFO RATE knob selects between clock divisions of the internal or
external MIDI clock.
KB RESET
When the Keyboard LFO Reset button is illuminated, the LFO will restart its cycle at zero each time a
new note is played. With KB RESET off, the LFO will run freely, and will not reset at the start of any notes.
PITCH AMT
Use this knob to specify the depth of pitch modulation applied to Oscillator 1, Oscillator 2, or Both of
the oscillators. The PITCH AMT knob is bipolar, meaning that its control value is positive when turned
up beyond 12 o’clock, and negative (or inverted) when turned down below 12 o’clock.
OSC
The OSC button is directly tied to the PITCH AMT knob, and is used to toggle between modulating the
pitch of oscillator 1 only, oscillator 2 only, or modulating both oscillator 1 and oscillator 2 simultaneously.
FILTER AMT
Use this knob to specify the positive or negative depth of variation applied to the filter’s cutoff
frequency. Applying LFO modulation to the filter is useful for generating slow filter sweeps, wobbles,
and repeating effects. This knob is bipolar, meaning that its control value is positive when turned up
beyond 12 o’clock, and negative (or inverted) when turned down below 12 o’clock.
CONTROLLERS
Pressing this button takes you to the MOD 1 or MOD 2 CONTROL menu on the LED display
screen. Here you can determine the amount of effect that the MODULATION wheel, VELOCITY,
AFTERTOUCH, and an assignable CONTROLLER 4, have on the modulation destinations. To learn more
about the MOD CONTROLLERS menu, got to page 50.
MOD AMT
Use this knob to assign positive or negative amounts of modulation to your selected destination
(DEST). This knob is bipolar, meaning that its control value is positive when turned up beyond 12
o’clock, and negative (or inverted) when turned down below 12 o’clock.
MOD DEST
This switch toggles through seven various modulation destinations, including LFO rate (of the other
LFO), VCA level, oscillator 1 waveshape, oscillator 2 waveshape, both oscillators’ waveshapes, noise
level, EG times, or other various destinations assigned via the MOD CONTROLLERS menu. To learn
more about the MOD CONTROLLERS menu, got to page 50.
