LFO 2
D The LFO 2 is a standard LFO but is not polyphonic like LFO 1. It is not as-
signed to any parameter in an “Init” patch so you have to use the Modu-
lation Routing section to use it.
• Also the LFO 2 “Delay” and “Key Sync” parameters are single trigger, i.e. the LFO
will not retrigger these parameters for legato notes.
D You select a LFO waveform by using the spin controls beside the wave-
form display, or by clicking in the display and moving the mouse up or
down.
The following parameters are available for LFO 2:
Modulation bus routing
section
A modulation bus is used to connect a modulation source to a modulation destination.
Both audio signals and control (CV) parameters are available. This creates a flexible
routing system that complements the pre-wired routing in the Voice panel.
Basic operation - simple tutorial
To illustrate the basic operation of the modulation bus section, let’s set up a simple
source to destination modulation assignment:
1. Select “Initialize Patch” from the Edit menu.
If you currently have unsaved settings you wish too keep, don’t forget to save them
first.
The Init patch is a simple 1 oscillator/1 filter setup, which produces sound when you
play, and will serve the purpose of this tutorial.
D The left half of the modulation section contains 5 columns, Source,
Amount, Dest, Amount and Scale.
Below the column headers there are 7 rows. Each row is a modulation bus where
you can have a Source to Destination modulation assigned.
2. Click in the top row of the leftmost Source column.
A pop-up menu appears listing all available Source modulation parameters.

Description
Rate This sets the frequency or rate of the LFO.
Waveform This sets the LFO waveform. Apart from standard waveforms
(sine, square etc.) there are various different random, non-linear
and stepped waveforms. The basic shape of the waveforms are
shown in the display, and illustrate how a signal is affected.
Delay This introduces a delay before the LFO modulation onset after a
note is played. Turn clockwise for longer delay.
Key Sync If Key Sync is off, the LFO cycle is free running, meaning that
when you play a note the modulation may start anywhere in the
LFO waveform cycle. If Key Sync is on, the LFO cycle is reset for
each note played.
Tempo sync If this is on, the Rate will be synced to the sequencer tempo in
beat increments (4/1 to 1/32).
