LXR OWNERS MANUAL

MODULATION PAGE (MOD)

The modulation page contains the velocity modulation parameters. Here you can turn 
the velocity volume modulation on and off and route the note velocity to any synthesis 
parameter you like. If the selected voice offers a second envelope, it's parameters can 
be found on the modulation page as well.

FREQUENCY MODULATION PAGE (FM)

The FM page hosts the frequency, waveform and modulation amount settings for 
the FM oscillators.

Drum 1-3, Snare

Displayed name Name

Description

Fall time of the envelope.

dec

Modulation envelope decay

Variable slope from exp to 

linear to logarithmic.

slp

Modulation envelope slope

Amount of the velocity 

modulation.

amt

Velocity mod. amount

Can be either On or Off.

If activated the note velocity 

controls the voice volume.

vol

Velocity to volume modulation

The note velocity can be routed 

to any voice parameter. Here you 

can select the target from a list.

dsr

Velocity mod. destination

> Controls how strongly the 

envelope modulates its target.

> The envelope is hardwired to 

the pitch. This parameter controls 

the pitch modulation intensity.

> In FM mode the EG is 

additionally hardwired to the FM 

amount.

mod

Modulation envelope amount

Clap, Hi-Hat

dst

Velocity mod. destination

Amount of the velocity modulation.

amt

Velocity mod. amount

Can be either On or Off. If 

activated the note velocity 

controls the voice volume.

vol

Velocity to volume 

modulation 

Displayed name

Name

Description

FM mode: modulation amount

Mix mode: Mix ratio of the 2 OSCs.

amt

Modulation amount 

[mix ratio]

Coarse tuning of the FM oscillator 

in semitones.

frq

Frequency of the FM OSC

The waveform of the FM oscillator.

wav

Waveform of the FM OSC

FM mode: the main OSC is 

modulated by the FM OSC

Mix mode: The main OSC and FM 

OSC are mixed.

mod

Oscillator mode
