If you set the Convert To field to Make new sample, this will
create a new sample in your project. (The original sample will
remain as it is.)
Important: Assigning a sample to a pad in this way will replace the
sample on the first layer of the pad.
Use the Pad field to select the desired pad. Alternatively, press
the desired pad.
Check the Crop Sample box to delete the unused parts from
the sample when it's created and assigned. This feature is
destructive, though the project will still contain your original
sample.
Leave this box unchecked to keep the unused parts of the
sample when it is created and assigned. This way, you will still
be able to edit the entire sample further even though you are
using only part of it at the moment.
Use the Program field to specify the program to which you
want to add the slice.
To convert the sample, tap Do It.
To cancel the operation, tap Close.
If you set the Convert To field to Patched phrase, this will create
a new sample that will play based on the tempo of your Sequence,
and places it in the current project. The patched phrase will have
the same name as the original sample but appended with pp and
will use a different icon when viewing your project information.
Use the Bars field to set how many bars long the patched
phrase is meant to be.
