Target Description

ASSIGN (DEST)

A freely selectable sound parameter for LFO modulation

ASSIGN (AMOUNT) Modulation intensity for the freely selected sound parameter

While you are dealing with one of the parameters discussed here, the corresponding LED will flash.

If this parameter is assigned a value other than 0, it will illuminate continuously when you exit the menu. Located between OSC 1 and OSC 2, you’ll find OSC 1+2. It lets you determine the modulation intensity collectively for both oscillators. When you select it position, both OSC 1 and OSC 2

LEDs will flash.

LFO CONTOUR

By LFO Contour you can now bend or ”morph” (almost) all the LFO waveforms. A brief survey of the

LFO Contour options for the different LFO modes follows:

Waveform

SINE

TRIANGLE

SAWTOOTH

SQUARE

WAVES

Function

Contour morphs from sine to a triangle wave (Contour to the left) or to a square wave (Contour to the right).

Contour morphs from a triangle to a declining (Contour to the left) or ascending sawtooth (Contour to the right).

Contour morphs from a linear declining sawtooth or decay to any exponentially declining decay(Contour to the left) or to a square (Contour to the right).

Contour modulates the pulse width of the square wave.

Contour ”zooms” into the wave, thereby shortening the wave’s loop length

(Contour to the right).

The Parameters

CLOCK

When you set it to OFF, the LFO oscillates in the normal manner, independently of the global Master

Clock (CLOCK TEMPO). When you enter a note value here, the LFO rate is synced up to the global master clock. The length of the waveshape’s cycle will then correspond to the note value that you have entered. You can also set the rate via CLOCK TEMPO (refer to the appropriate section) or synchronize it to external MIDI clock. When the LFO is synced up to the master clock, you can also select the desired note value via the LFO RATE knob.

LFO MODE

Value

POLY

MONO

Description

In polyphonic mode, each of the voices involved is assigned a dedicated

LFO. The LFOs oscillate in different phase positions for each voice. This livens up the LFO modulation.

In polyphonic mode, all voices are assigned the same LFO. This accentuates the LFO modulation, making it more pronounced.

TRIGGER PHASE

Selects the position in the wave cycle - i.e. the phase position - at which the LFO starts oscillating in response to the start of a note. The control range of 1 to 127 is equivalent to phase positions of 0 to

360 degrees; the value 0 switches the KEY TRIGGER function completely off so that the LFO oscillates freely and appears on random phase positions at the start of a note.

KEY FOLLOW

Controls the intensity of the KEY FOLLOW function - i.e. the rate at which the LFO follows the pitch of a played note. At a value of 0, KEY FOLLOW is deactivated. At a value of 127, the rate doubles with each octave.

FILTER GAIN

An additional modulation destination of LFO 1. Here the input level of the filter section is modulated

(and thus the subsequent saturation level). The effect of a FILT GAIN modulation is a periodic change in the saturation level which is linked to a corresponding tremolo (periodic change in volume). If the signal is not saturated in any manner, then the only audible result is a tremolo effect. We
