Time Slice

Mono Time
Remaining sample memory (in seconds). This value is given for
mono samples. With stereo samples, this time has to be halved.
Bytes
Remaining memory for sampling (in Bytes). This value is given
for mono samples. With stereo samples, this time has to be
halved.
Sample Info

Size of the selected sample (in samples).
Samples
Total size of the samples in memory (in samples).
Sampling Frequency

Time Slice
The Time Slice function lets you transform a rhythm audio
groove in a series of single percussive samples, to be assigned to a
Style or Song Drum or Percussion track.
Some theory...
Analyzing and processing. This function detects the attacks
(e.g., kick and snare) inside a rhythm audio groove (a sample
that loops a drum pattern), and automatically divides the audio
groove into individual percussive samples.
The divided percussive samples will be automatically assigned to
a multisample, and the multisample to a Sound.
Within the generated multisample, a separate sample is assigned
to a different note on the keyboard, starting from C#3. By play-
ing an ascending chromatic scale with this multisample, you
could recreate the original audio groove.
A MIDI Groove will also be created, containing a sequence of
notes triggering the sliced percussive samples in the same order
as in the original audio groove (i.e., it plays an ascending chro-
matic scale starting from C#3).
When you will import this MIDI Groove to the percussive track
of a Style (see "Import: Import Groove" on page 121), this
sequence will let you adjust the groove's tempo without affecting
the pitch of the percussive samples.
In addition to changing the groove's tempo without affecting its
pitch, this lets you do the following:
• change the order in which notes are played
• change the timing
• edit the pattern notes to freely recreate a new rhythm loop.
Saving. After the slicing, you can select the Write command
from the page menu, to save the Sound based on sliced samples,
and the MIDI Groove containing the corresponding MIDI
sequence.
• The Sound will be saved to the selected location in the User
area of the internal memory. You will be able to select it as an
ordinary Sound, and assign it to the Drum or Percussion track of
a Style.
• The Multisample will be automatically saved to the next free
available location.
• Samples will be permanently saved to the PCM folder on the
hard disk. They can be automatically loaded when turning the
instrument on, by checking the "PCM Autoload" option in Disk
mode (see page 273).
• The MIDI Groove will be temporarily saved to the SSD mem-
ory, and will be available only when using the Import function of
the Style Record mode (see "Import: Import Groove" on
page 121).
Warning: All MIDI Grooves will be delete each time the Pa1X is
turned off.
