The LFO Page

The LFO page is used to change settings for the optional LFO (Low Frequency Oscillator) generator of the currently selected split. The LFO envelope is a curve that is applied to the LFO output of the split. This page is also used to apply general LFO settings to the currently selected split as well as LFO target information.

The LFO Envelope Display

An LFO envelope curve has four sections (ADSR):

If you want to start the LFO with a higher level than 0, you also can set the start level for the sound. LFO levels are directly applied to the output of the LFO and therefore affect the LFO target.

Each section has rates from 0-63 and levels from 0-255. A level of 255 means full LFO effect for the sound whereas a level of 0 means no LFO effect. The rate specifies the time to reach the specified level for that section. This setting depends on the timer resolution set in the Settings page. By default the timer resolution is 10ms, so you can achieve rates ranging from 0ms to 630ms. If you need higher rates, you can set the EG multiplier to a value above 1. The EG multiplier settings will multiply the rates with the given value. Valid values are 0-20, so with an EG multiplier of 20 you would achieve rates from 0ms to 12.6s. Note that precision decreases if you set the EG multiplier to a higher value. With an EG multiplier of 1 for example the rate 1 results in a time of 10ms whereas with an EG multiplier of 20 it would be 200ms. Note that the envelope is only used if you activate the "EG enabled" checkbox.

You can change rates and levels by pressing the left mouse button over the nodes in the EG curve and drag it with the mouse to the desired position.

General LFO Settings

Three controls are responsible to specify general LFO settings:

LFO Target Settings

The LFO target settings are used to specify the target of the LFO (the sound parameter that the LFO is applied to) and the amount of LFO that should be applied to the target parameter. The following parameters are selectable:

The "Range" controls specify the range that should be applied with the LFO to the target parameter. The actual change values are calculated from the waveform output of the LFO and the range given and are applied to the target. For example with a LFO target "Pan" and the range between -64 and 64, the LFO would have maximum effect on the panning of the sound allowing the sound to oscillate between the left and the right channel when you choose the "sine" waveform.

Changing all splits for a Preset in one step

The checkbox "Change all splits" is used to apply all changes to this page to all splits of the selected Preset (instrument). That means your changes will be applied to all splits and therefore override the old values. This is especially useful for envelope settings that typically are equal for all splits of a Preset.
