INTERNAL CONTROLLERS
LFO1 + LFO2
A Low Frequency Oscillator (“LFO”)
generates control signals in the form of a
variety of periodic wave shapes. Examples of LFOs
in use include the pulse of a tremolo, the back and
forth sweep of a phaser, or the random lter in Ship
Ahoy by Frank Zappa.
Type sets the waveform or shape. You can set the
Rate or lock the LFO to the current Tempo. You can
vary the overall Depth and Duty, or symmetry. The
Run parameter starts and stops the LFO. This can be
used to keep it from drifting out of time.
Each LFO outputs “A” and “B” signals, each of which
is an independent modier source on the list. You
can change the Phase of output B with respect to A.
Quantize changes smooth waveforms into stepped
ones. Try it on the “TRI” waveform for example.
TEMPO
SEQUENCER
The Step-Sequencer generates control
patterns by looping through 2–32 “stag-
es.” You set the Value for each stage, the
Number of stages, and the Rate or Tempo. The Run
switch allows you to start or stop the sequence.
Damping slurs the change between steps.
SCENE CONTROLLERS
The four Scene Controllers provide a way
to change sound settings from one Scene
to another. Think of each Scene Controller
as a “virtual knob” whose setting can programmed
with a different value in every Scene. By assigning
this knob as a modier source, you can create “per-
scene” parameters.
For example, you might assign Scene Controller 1 to
Input Drive in the Amp block with a value of 10% in
Scene1, 50% in Scene2, 75% in Scene 3, and so on.
As with any source, a scene controller can be
assigned to multiple parameters at the same time,
each with its own modier settings.
A Scene Controllers tutorial appears on p. 68.
For more on Scenes, see Section 6 on p. 49.
PITCH DETECTOR
The Pitch Detector analyzes the pitch of
your playing and outputs a low value for
low notes and a high value for high notes.
ADSR1 + ADSR2
The two ADSR sources are envelope
generators with Attack, Decay, Sustain
and Release parameters (thus “ADSR”). The ADSR
is triggered whenever the signal level exceeds its
Threshold measured at the selected input (1 or 2).
The envelope has three self-explanatory modes
(Once, Loop, and Sustain) and can optionally be set
to Retrigger every time the threshold is exceeded.
In comparison to the Envelope Follower, the ADSR
envelope generator always creates the same control
signal, but only triggers when you play hard enough.
ENVELOPE FOLLOWER
This converts input level to a control signal,
responding variably to your playing dynam-
ics. The classic example is a touch-wah,
where the frequency of the wah varies based on how
hard you play. You can set Attack and Release times
independently, set the trigger Threshold, and adjust
the Gain at the trigger signal input, which can be set
to Input 1 or Input 2.
Internal Controllers can be programmed per-preset for use as modier sources. To access these parameters,
push the CONTROLLERS button on the Home page (Push-knob D) or press TEMPO.
Tempo appears in the Controllers menu. For more information, see Section 11: Tempo.
The Internal Controllers menu offers four channels for four sets of independent settings for ALL of
the items listed above: four tempos per preset, four sequencer settings, etc. When you change the
channel, ALL of the controllers switch to the new channel and the new settings. FM3-Edit provides a
way to copy/paste Controller channels.
