Chapter 4 EFM1 109
EFM1 is divided into several areas.
•
Global parameters: The top section contains parameters that set the overall tuning of EFM1.
Further controls enable you to set the Glide (portamento) time, limit the number of voices, and
thicken the sound with Unison. See EFM1 global parameters on page 114 .
•
Modulator and Carrier parameters: The FM engine consists of the modulator and carrier
parameters (raised, darker sections), and the FM Intensity knob (in the center). These are
the key controls for setting the basic tone of EFM1. See Modulator and carrier overview on
page 110 .
•
Modulation parameters: The modulation envelope and LFO at the top and bottom of the
mushroom-shaped area in the center respectively are used to animate the sound. See EFM1
modulation parameters on page 113 .
•
Output parameters: The bottom section houses the Output section, which includes the Sub
Osc Level and Stereo Detune knobs that can be used to thicken the sound. The volume
envelope, Main Level, and Velocity controls are used to set the EFM1 level. See EFM1 output
parameters on page 115 .
•
Randomize parameters: The Randomize eld and button in the lower-right corner are used to
create random variations of the current settings, resulting in new sounds. See Create random
EFM1 sounds on page 116 .
•
Extended parameters: Accessed by clicking the disclosure triangle at the lower left of the
interface, these parameters allow you to assign MIDI controllers to the FM Depth and Vibrato
parameters. See EFM1 extended parameters and EFM1 MIDI controller assignments on
page 117.
