Sampling and Sample Editing
Editing Samples
Decay Rate
This parameter deÞnes how long the sample takes to decay (fade) to zero amplitude (silence).
Decay Rate affects each sample individually, and is in effect only when the amplitude envelope
for the program (the Mode parameter on the AMPENV page in the Program Editor) is set to
Natural. If Mode is User, the settings on the AMPENV page override the setting for DecayRate.
DecayRate operates in two different ways, depending on the nature of the sample. If itÕs a ROM
sample or a Kurzweil-format RAM sample, DecayRate takes effect in the loop portion of the
sample, after all the attack stages of the amplitude envelope are complete. For non-Kurzweil
RAM samples, DecayRate takes effect as soon as the sample starts, regardless of the length of the
attack stages.
Release Rate
The release rate determines how long the sample will take to decay to zero amplitude when the
note trigger is released. The higher the value, the faster the release rate.This release affects each
sample individually, and is in effect only when the amplitude envelope for the program (the
Mode parameter on the AMPENV page in the Program Editor) is set to Natural. In this case, the
release begins as soon as the note is released.If Mode is User, the settings on the AMPENV page
override the setting for ReleaseRate.
To create an extended sample loop that will play data after the sampleÕs loop on key-up, set the
Alt sample pointer after the sample end pointer, then set a relatively low value for the release
rate.
Loop Switch
This parameter activates or deactivates the looping of the currently selected sample. When set to
On, the sample will loop according to the settings on the LOOP page. When set to Off, the
sample will play through to its End point and stop.
Playback Mode (Playback)
This parameter lets you modify the direction in which the sample is played. Set it to a value of
Reverse if you want the sample to play from its End (E) point to its Start (S) point. Choose a
value of Bidirectional to cause the sample to play from Start to End, then reverse direction and
play again from End to Loop and back, repeating until the note trigger is released (this works
only when the Loop Switch parameter is set to On).
Alternative Sample Sense (AltSense)
This provides a convenient way to activate the alternative start of a sample. When set to
Normal, the alternative start will be used when the Alt Switch control is On (this is set on the
KEYMAP page), or when the control source assigned to it is above its midpoint. When set to
Reverse, the alternative start will be used when the Alt Switch control is Off, or when the
control source assigned to it is below its midpoint.
Ignore Release (IgnRelease)
When set to a value of Off, the sample will release normally when the note trigger is released.
When set to On, the note will not release, even when the note trigger is released. This setting
should be used only with samples that normally decay to silence; nondecaying samples will
play forever at this setting. This parameter is equivalent to the IgnRelease parameter on the
LAYER page, but affects only the currently selected sample.
