Table Of Contents
Tune field: Used to fine-tune the pitch of the EFM1 by cents. A cent is 1/100th of a
semitone.
Voices pop-up menu: Determines the number of simultaneously playable voices
(polyphony). Click the pop-up menu to choose from mono (one voice), legato (one
voice), or any number from 2 to 16 voices.
Note: In the monophonic, legato mode, playing overlapping notes does not retrigger
the EFM1 envelopes.
Unison button: Turn on the Unison button to layer two complete EFM1 voices, thus
making the sound larger and fatter. The EFM1 can be played with (up to) 8-voice
polyphony when in unison mode.
Glide field: Used to introduce a continuous pitch bend between two consecutively
played notes. Adjust the Glide value (in ms) to determine the time it takes for the pitch
to travel from the last played note to the next.
Note: Glide can be used in both of the monophonic (mono and legato) modes, or in
any of the polyphonic settings (Voices parameter = 2 to 16).
Setting EFM1 Output Parameters
The EFM1 provides the following level controls.
Main Level knob
Volume envelope
Velocity knob
Stereo Detune knob
Sub Osc Level knob
Sub Osc Level knob: Used for added bass response. The EFM1 features a sine wave sub
oscillator. This operates one octave below the FM engine (as determined by the
Transpose parameter). Turning up the Sub Osc Level control mixes the sub oscillator
sine wave with the EFM1’s FM engine output.
Stereo Detune knob: Adds a rich and diverse chorus-like effect to the sound of the EFM1.
This is achieved by doubling the EFM1 voice with a secondary, detuned FM engine.
High values result in a wide stereo effect being added to the detuning, increasing the
perceived space and width of your sound.
Note: It is possible that mono compatibility can be lost with use of this parameter.
