176 Chapter 15 EFM1
 The bottom section houses the Output section, and features the Sub Osc Level and
Stereo Detune parameters, plus the volume envelope, Main Level, and Velocity
controls. A Randomize field is shown to the lower right.
 The extended parameters panel (accessed by clicking the disclosure triangle at the
lower left) allows you to assign MIDI controllers to the FM Amount (FM depth, in
other words) and Vibrato parameters.
Global Parameters
These parameters impact on the overall instrument sound produced by the EFM1.
Transpose
The base pitch is set with the Transpose parameter. You can transpose the EFM1 by ±2
octaves.
Tune
Tune will fine-tune the EFM1 ± 50 cents. A cent is 1/100th of a semitone.
Unison
Enabling the Unison button will layer two complete EFM1 voices, making the EFM1
sound larger and fatter. In Unison mode, the EFM1 can be played with 8-voice
polyphony.
Voices
The number of simultaneously playable voices (polyphony) is determined by the Voices
parameter. Available values are: Mono (one voice), Legato (one voice) and 2 to 16
voices. In the monophonic Legato mode, playing overlapping notes will not retrigger
the EFM 1 envelopes.
Glide
Glide is used to introduce a continuous pitch bend between two consecutively played
notes. The Glide value (in ms) determines the time it takes for the pitch to travel from
the last played note to the next. Glide can be used in both of the monophonic Mono
and Legato Voices modes, as well as with the polyphonic Voices settings (2 to 16).
Randomize
The Randomize facility (shown at the lower right of the interface) generates new
sounds with each click on the Randomize button. The amount of randomization (or
variance from the original sound) is determined by the value set in the numeric field.
You should use values below 10% if you only want to randomly tweak the current
sound.
