> CTRL SMOOTH
Many digital synths, including many 'soft' synths in particular, cannot affect parame-
ter changes without producing audible artefacts or 'zipper noise'. This is because the resolu-
tion of the controllers is not high enough to affect smooth changes in realtime. The Virus
PowerCore compensates for this however, by using Adaptive Parameter Smoothing or 'Con-
trol Smoothing'. This means that instead of jumping between each step at the resolution of
the controller (128 steps maximum), the Virus PowerCore takes advantage of the higher inter-
nal resolution of the PowerCore's DSP to interpolate between the values. The result is
smooth, discreet changes with no zipper noise. Some patches may require more instantane-
ous jumps than Ctrl Smooth can achieve though, so the following options are made available:
> Off:
No smoothing is applied to the current patch.
> On:
Smoothing is applied to all relevent parameters.
> Auto:
Smoothing is applied to parameters whose value is changed slowly, but sudden
jumps are not smoothed.
> Note:
Smoothing is applied within a note's duration, but is disabled at Note Off i.e. param-
eter changes affected by MIDI note number or Note On will not be smoothed.
> HOLD PEDAL
Enables or disables the response to a sustain pedal, which keyboard players often use to
hold notes even after the key is released.
> NOTE STEAL
If the Virus PowerCore is asked to play more notes than the available polyphony allows, then
'note-stealing' occurs. This means that all currently playing voices are analysed for their cur-
rent state, and the Virus PowerCore intelligently silences one voice to make room for the new
one. When more than one part within the same instance is being used, then the note-stealing
algorithm has to decide which plug-in loses a voice in favour of another. This is where High
and Low Priority come in:
> Low Priority :
When an instance is set to Low Priority, preference is deferred to any other
instances which are set to High Priority.
