Snap To Zero-Crossings
When this function is on, sample selections made by dragging or clicking in the
waveform display will automatically snap to the nearest zero-crossing points when the
mouse button is released. For stereo samples, the zero-crossing is determined by the
nearest zero-crossing on either channel. See also “Zero Crossing” on page 185.
Turn this function on, either by pressing the Toolbar button or by selecting it from
the Sample Edit pull-down menu.
Adjustments to the selection using the keyboard, and menu command selections are
not affected by this switch. The switch holds its setting for each sample.
Background: Zero Crossing Threshold
The Zero Crossing Threshold determines
how close to zero a sample has to be to
qualify as a zero crossing. This allows more
points to be selected as zero crossings.
To qualify as a zero crossing, the wave must
have passed through the zero line since the
last selected zero crossing and the sample
must lie inside the zero crossing threshold.
In the example on the right, the samples
marked in red will be selected as zero
crossings. See also “Zero Crossing” on
page 185.
To Change the Zero Crossing
Threshold
1. Enable “Show Zero Crossing Threshold”
from the Display menu, or by pressing
the toolbar button. Z
2. Press the Vertical Zoom button until you
can see the Zero Crossing Threshold Markers on the left side of the waveform
display.
3. Drag the markers apart to select more zero crossings. PLace them closer together to
exclude more zero crossings.
Delete Unused Samples
When creating a custom bank, you may end up with a bunch of unused samples which
are not used in any of the presets you created. This utility allows you to discard the
unused samples from the bank.
To Delete Unused Samples from the Bank
1. Right-click on the sample folder in the tree.
2. Select Delete Unused Samples.
