••
LFO (low frequency oscillator) knob: Rotate to set the amount of modulation applied to
FM intensity or pitch.
••
If you turn the LFO knob clockwise, you increase the effect of the LFO on FM Intensity. If you
turn the knob counterclockwise, you introduce a vibrato.
••
If you click the “0” to center the LFO knob, the LFO has no effect.
••
Rate knob: Rotate to set the speed of the LFO.
EFM1 global parameters
The global parameters are used to set the tuning, number of voices, and other aspects of the
EFM1’s overall sound.
Global parameters
••
Transpose pop-up menu: Choose the base pitch. You can transpose EFM1 by semitones or
octaves with this control.
••
Tune field: Drag to fine-tune the pitch of EFM1 by cents. One cent is 1/100th of a semitone.
••
Voices pop-up menu: Choose the number of simultaneously playable voices—polyphony. You
can choose mono (one voice), legato (one voice), or any number from 2 to 16 voices.
••
In Mono mode, staccato playing retriggers the envelope generators every time a new note
is played. If you play in a legato style (play a new key while holding another), the envelope
generators are triggered only for the first note you play legato, then they continue their
curve until you release the last legato played key.
••
Legato mode is also monophonic, but with one difference: the envelope generators are
retriggered only if you play staccato—releasing each key before playing a new key. If you
play in a legato style, envelopes are not retriggered.
Note: On several monophonic synthesizers, the behavior in Legato mode is referred to as
single trigger, while Mono mode is referred to as multi trigger.
••
Unison button: Turn on to layer two complete EFM1 voices, thus making the sound richer. EFM1
can be played with up to eight-voice polyphony when in unison mode.
••
Glide field: Drag to introduce a continuous pitch bend between two consecutively played
notes. Adjust the Glide value, which is 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 modes—Mono and Legato—or in any of
the polyphonic settings—where Voices is set from 2 to 16.
