The Filter Page

The Filter page is used to change settings for the filter envelope of the currently selected split. The envelope is a curve that is applied to the filter output (filter frequency) of the split. This page is also used to apply filter velocity settings to the currently selected split as well as filter parameter (frequency and quality)  information. Note that this page is eventually not available for a split if you use the DirectSound interface for that split. This may change in future versions of Virtual Sampler by taking advantage of DirectX plugins.

The Filter Envelope Display

A filter envelope curve has four sections (ADSR):

If you want to start the filter with a higher level than 0, you also can set the start level for the filter.

Each section has rates from 0-63 and levels from 0-255. A level of 255 means that the full filter frequency as specified with the FilterFC knob is applied to the sound whereas a level of 0 means that the filter is completely closed (silence). The filter level is directly applied to the filter frequency (FilterFC knob). 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, otherwise the filter is static (does not change over time).

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 Filter Settings

Two knobs are responsible to specify general filter settings:

Filter Velocity Settings

These settings affect velocity behaviour of the filter for the selected split. Velocity is the strength that is used to play a specific note. MIDI velocity ranges from 0 (no velocity at all) to 127 (highest velocity). Note: Virtual Sampler will only receive velocity data if you select the "Receive Channel Velocity" entry on the Settings page. The following options are available:

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.
