Wave editor
: Loop points, Cue points and pixelwise move buttons
Pixelwise move buttons
The +1 and -1 buttons act on your last
selected cue point, loop point or selection-end and allow a pixelwise
movement of that object.
Loop points (minimum/maximum 2)
There are two flags which are called loop points, they can only
appear together on the screen.
You can create loop points by pressing the loop button. If no
loop points are currently on screen, they are created at the outer
edges.
If a selection has been created before, the loop points
are created at the outer edges of the selection.
Your loop also starts playing immediatelly after pressing the
loop button. So this button's function is to make the loop points
visible if the were not and/or to start playing a set loop.
If one loop point is selected and deleted, the other one will
also be deleted. Delete with the DEL key. Deselect a loop point
by selecting the other one or a cue point, by touching the end
of a selection or pressing ESC.
If you later use a wave file by Virtual Sample Player as
a part of a multisample instrument, a loop is started at the beginning
of the file and looped in the loop area, when the 2. loop point
is reached. It is a good idea to delete the piece of wave beyond
the 2. loop point, it will never be played and just consumes disk
space.
If you define a loop area and want to make MIDI Locator's
wave editor also start playing at the beginning of your wave file
and then loop between the loop points, press the
button.
You can also change the position of visible loop points if you
double-click the head of a loop point-flag. A dialog window appears
:
The position of a loop point is it's physical address inside the
wave file. Please notice, that the wave file does not only contain
the audio data of the waveform. And the audio data (where the
loop point is the address of a sample) is not the first data in
it. So the dialog shows the "wave start address", which
is the first sample's offset in your wave file. The samples themselves
are not nummerated in single steps, a 16 bit wave file's sample
increases the address pointer by 2. A 24 bit sample increases
it by 3. Stereo samples increase the address by doubled steps
!
Cue points (maximum 10)
You can set a cue point where you want, by pressing the cue point
button . Each set cue point can be selected
seperate by touching it's head and can be moved or removed. Remove
them from screen with the DEL key. Deselect a cuepoint by selecting
another one, a loop point, touching the end of a SELECTION or
pressing ESC.
The cue points are only positioning helpers for you. They have
no audible relevance. You can set a maximum of 10 cue points.
They are stored in the wave file itself.
