83 SOUND PARAMETERS REFERENCE
Contour
Accessible from the panel via SHIFT + RATE.
> -64 to +63: Continuous control over LFO waveform. Modula-
tion destination “LFO1 Contour“.
Mode
> Poly: Each voice has its own LFO, and these are slightly
detuned against each other.
> Mono: All voices share a common LFO. Only applies if the
parameters Envelope Mode and Trigger Phase (see below)
are both set to “Off”.
Envelope Mode
Accessible from the panel via the ENV MODE button.
> Off: Standard (cyclic) LFO mode.
> On: The LFO effectively becomes an additional Envelope.
LFOs in Envelope Mode are unipolar (see glossary) and stop
after completing exactly one cycle. The start/finish point
within the wave can be specified via Trigger Phase...
Trigger Phase
> Off, 1 to 127: When set to Off, LFO1 runs freely i.e. its phase
is not reset by every note played (except in Envelope Mode).
All other values set the starting point within the wave.
SHAPE NEGATIVE POSITIVE
Sine to Triangle to Square
Triangle to falling Saw to rising Saw
Saw concavity convexity
Square pulse width <50% pulse width >50%
