Realtime pitch shifting of audio 
events
Audio events can be pitch-shifted in real time just like MIDI 
events. 
The process is very simple:
1.Select one or several audio events in the Project win-
dow.
Audio parts cannot be transposed.
2.Open the event info line.
3.Set a value in the Transpose field to the far right on the 
info line.
The value range is up/down two octaves in semitone steps. 
4.Press [Enter].
All selected audio events are now transposed to the set...

Background
Hitpoint detection is a special feature of the Sample Edi-
tor. It detects attack transients in an audio file and then 
adds a type of marker, a “hitpoint”, at each transient. 
These hitpoints allow you to create “slices”, where each 
slice ideally represents each individual sound or “beat” in 
a loop (drum or other rhythmic loops work best with this 
feature). When you have successfully sliced the audio file, 
you can do a number of useful things with...

4.If you now move the hitpoint sensitivity slider to the 
left, this gradually hides the hitpoints. Moving the slider to 
the right increases the sensitivity to reveal additional hit-
points detected during the calculate process.
The basic aim is to add, remove or in various other ways edit the hitpoints 
so that one individual sound is played between each hitpoint. For details, 
see “Editing hitpoints” on page 124.
In the next step, the loop will adapt to the...

Auditioning slices
A slice is a section of the waveform, from one hitpoint to 
the next. 
The first thing you should do before editing hitpoints is to 
listen to each slice in the Sample Editor to determine what 
they contain. The aim is to avoid “double hits”, like a snare 
hit being followed by a hi-hat hit within the same slice. You 
also want to determine whether any hitpoints have been 
added that should be removed: 
1.Open a loop in the Sample Editor.
If you...

Disabling slices
You might run into situations where there are too many 
slices – a single sound may have been split into two 
slices, for example. You could of course reduce the sensi-
tivity to get rid of the hitpoints you don’t want, but then 
other hitpoints could disappear too, which may be unde-
sirable. What you need to do in a situation like this is to 
disable an individual slice using the Hitpoint Edit tool:
1.Select the Hitpoint Edit tool.
2.Press...

If you click and keep the mouse button pressed, you can 
adjust the position of the new hitpoint by dragging.
Releasing the mouse button adds the hitpoint.
5.Audition the new slice with the Play tool to make sure 
you got what you wanted.
Moving hitpoints
If you manually added a hitpoint, and it was either placed 
too far away from the start of the sound or too far into the 
sound, you can manually move the hitpoint. It is also pos-
sible to move calculated hitpoints...

Other hitpoint functions
On the various submenus on the Audio menu, you will also 
find the following functions:
Create Markers from Hitpoints
This is located on the Hitpoints submenu. If an audio event 
contains calculated hitpoints, this function can be used to 
add markers – one for each hitpoint – to an existing or auto-
matically created marker track (see “Using the Marker track” 
on page 72). This can be useful for locating to hitpoints.

The Pool
Background
What is the Pool?
Every time you record on an audio track, a file is created 
on your hard disk. A reference to this file – a clip – is also 
added to the Pool. Two general rules apply to the Pool:
All audio and video clips that belong to a project are 
listed in the Pool.
There is a separate Pool for every project.
The way the Pool displays folders and their contents is 
similar to the way the Mac OS X Finder and the Windows 
Explorer display folders and lists of files.
