LFO 1 – Panel
RATE
Determines the speed or rate of the LFO. In polyphonic sounds, the manually selected RATE value
deviates slightly from voice to voice to liven up the sound of the LFOs, which also oscillate poly-
phonically. When the LFO is synced up to the master clock, the desired note value is selected via
the RATE knob.
SHAPE
Determines the waveshape of the LFO. You can select from a sine, triangle, sawtooth or pulse
wave. WAVE opens a local menu. Here you can select 64 further LFO waveshapes in the display
using the VALUE knob or the VALUE buttons. You can chose from a stepped random modulation
(S&H; short for Sample & Hold), a smooth random modulation (S&G; short for Sample & Glide) and
62 cyclic modulations that are based on the oscillator modes. The latter allow you to create interest-
ing rhythmic LFO modulations.
ENV MODE
Activates an operating mode in which the LFO oscillates like an envelope: The LFO cycles once
only following the start of the note; the response of the LFO shifts from bipolar to unipolar. If the
LFO waveshape S&H (Sample & Hold) is active, then the LFO is assigned a new random value with
each new note. This new value is valid for the entire duration of the note.
AMOUNT
This button does not actually control a parameter, it opens a local menu. This menu contains inde-
pendent modulation intensities for controlling the following parameters via LFO 1:

OSC 2
PW 1+2
RESO 1+2
