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.
