The Sample Oscillator Section
Preload
HALion provides two different ways of working with sample data. A sample can either
be loaded completely into RAM or it can be streamed from the hard disk. However,
when samples are streamed, HALion needs to preload a portion of these samples to
be able to play a voice without having to search for the sample data first. The size of
this preload buffer can be set in the Options editor. The Preload setting enables you
to adapt this buffer size for individual sample zones by setting a multiplier from 1 to 16.
Increasing the buffer size can be useful if a sample can be transposed in a wide range
and HALion needs to read out the sample data faster, for example.
If you set Preload to its maximum, HALion preloads the complete sample. This option
is useful for smaller samples.
Sample Start Range
The "Sample Start Range" parameter allows you to determine the range for sample
start offset modulation. When "Sample Start" is selected as a modulation destination
in the modulation matrix, the "Sample Start Range" parameter controls the range, that
means, the sample portion that is affected by the start offset modulation. If this
parameter is set to zero, no sample start modulation is performed.
For example, if note-on velocity is used to modulate the sample start parameter, a high
key velocity starts playback later in the sample, and the range of this modulation is
determined by the Range Start parameter.
Fixed Pitch
When a sample zone is triggered by a MIDI note other than the one defined by the
Root Key setting, the sample is normally pitched accordingly. When Fixed Pitch is
activated, the relation between played note and root key is disregarded and all keys
play the sample just like it was recorded.
You can still apply the usual pitch modulations in the Pitch section and set the sample
to follow the keyboard according to the "Key Follow Root Key" setting.
The Loop Tab
The options on the Loop tab are identical with the loop options on the Loop tab of the
Sample editor, see "Creating Loops" on page 150.
