Module: ANALOG PROCESSING 16 Function: LFO TO (VIBRATO,
TREMOLO, FILTER Fc, PANNING)
The LFO can modulate four different parameters - - pitch, amplitude, filter cutoff frequency, and
stereo placement. The modulation depth (index) is variable from 00 to 15.
Application: LFO modulating the pitch provides vibrato effects; LFO modulating VCA provides tremolo
effects (as used for years in guitar amplifiers--attention surf music fans); LFO modulating fitter provides
timbre modulation effects; LFO modulating panning sweeps the sound back and forth between the left
and right channels (i.e., spatial modulation).
1. Activate ANALOG PROCESSING 16. The display will say:
2. Select the desired parameter for adjustment with the cursor buttons, then use the data slider or
increment buttons to change the parameter value as desired:
Vibrato: Determines the extent to which the LFO modulates pitch. Range is from 00 to 15,
with higher values giving more modulation.
Tremolo: Determines the extent to which the LFO modulates the VCA. Range is from 00 to
15, with higher values giving more modulation.
Fc (filter cutoff): Determines the extent to which the LFO modulates the filter cutoff frequency.
Range is from 00 to 15, with higher values giving more modulation.
Pan: Determines the extent to which the LFO modulates the stereo placement. Range
is from 00 to 15, with higher values giving more drastic motion between the left
and right channels.
3. After making your selections, press ENTER to return to the Module Identifier.
Module: ANALOG PROCESSING 17 Function: VELOCITY TO (LEVEL,
FILTER Fc, FILTER 0, PITCH)
This function ties dynamics (level), filter cutoff, filter 0, and pitch to how forcefully you play the
keyboard.
Application: Sample sounds from an instrument (i.e. older synthesizers) without dynamics, and assign
dynamics.
Application: Acoustic instruments often sound brighter when played forcefully. Emax can simulate this
effect by tying fitter cutoff to keyboard dynamics.
Application: Increasing 0 with increasing velocity thins out a sound, yet also increases its sharpness.
This can work well with percussive Voices when you want a more intense, but not necessarily louder,
sound.
Application: Since each Voice in a Preset can have its own keyboard dynamics settings, lower register
bass sounds can have minimum dynamics to provide a constant bottom, while upper register lead sounds
can be played more dynamically.
