1-1 Introduction


The wave converter tool is used to convert waves into the Sound Format (Tone with Wave), which can be loaded by the WK3000, WK3500 and CTK691.

The basic function of Wave Converter is to load audio samples (.wav format, described hereafter as "waves") and map them across the keyboard in up to 16 different zones. This means that you can have up to 16 different samples each playing in a different range across the keyboard. These could be different pitches of the same instrument (for example a piano or guitar sample) or they could be completely different instruments (for example drum instruments).

There are some basic functions to alter how the samples work in the final Tone with Wave Format , and we'll look at these in detail in chapter 3. If you have a basic knowledge of sampling, Wave Converter will be very easy for you to use.

It is important to realize that Wave Converter is not a sampler itself. You must create waves (ie: samples) in a suitable Digital Audio programe, or load them from an existing library. Wave Converter is a tool for combining up to 16 waves into a Tone with Wave, in which those waves are mapped across the keyboard in distinct zones.


2-1 The Basics


To start Wave Converter and the start up page of the Wave Converter will appear as follows:.



The desktop is divided into three main sections: The Menu Bar, The Keyboard Graphic and the Sample Panels.



2-2 The Desktop

File Menu



The file menu has five options, plus the option to exit completely from the Wave Converter. Three of the options have to do with loading and saving "parameters". Parameters are literally the settings you make in your Wave Converter project.

New :
Starts a new project
Open Parameter :
Load a previous project
Save Parameter :
Save the current project. Note that if it is a new project which you haven't already saved, you will be given the option to name it, or just save it as "untitled", just as in any Windows application
Save As Parameter :
If you have already saved your project and you want to save it again under another name, use the "Save As" option just as in any Windows application
Convert :
After you've completed all of the parameter settings in Wave Converter, use "Convert" to create the finished Tone with Wave file
(The Convert Button under the File Menu is same function of this menu.)

Edit Menu



The Edit Menu gives you the option to add or delete "Splits". This means adding more waves to your final Casio Sound. (Tone with Wave) When you start Wave Converter it defaults to three splits, which means that you could have three waves, one in each of the three split zones.

If you are creating a Tone with Wave which is of a complex instrument such as a guitar or piano, the more waves you use at different pitches, the more accurate the sound will be. You can use up to 16 Splits (ie: waves) in your Tone with Wave, so to add more splits just click on "Add Split" in the Edit Menu. If you want to delete a Split just highlight the split you want to delete (click on the bar above the words "Wave File" and click so the bar changes to green) and select "Del Split" in the Edit Menu.

Procedure to delete a Split:
Step 1

Step 2








Keyboard Range

You can select whether your finished Tone with Wave is for a 61 note keyboard or a 76 note keyboard. As mentioned in the introduction you can use your finished sound in the WK3000, WK3500 and CTK691. The WK3000 and WK3500 both have 76 keys and the CTK691 has 61 keys, so make your selection depending on the instrument for which your sound is intended.


Just click on the Keyboard Range menu and make your selection, the graphic of the keyboard will change when you change Keyboard Range:





Note
:
that the original pitch of the waves you use is important when you consider the total range of the keyboard. If you are creating an instrument sound with a very wide range such as Piano, it is important to use waves which cover the whole range of the keyboard you are working with.

The keyboard graphic shows you the area of the keyboard on which a wave will play, and the original note (pitch) of the wave. In the above example the different zones set are shown by the verticle dividing red lines, and the currently selected zone is highlighted with a horizontal red line just above the keys. The original pitch of the wave is indicated by the small box just under the keys, in this case showing D3. (The box indicating the original pitch of the wave and the range in which the wave is active are highlighted in the same color as the bar at the top of the wave panel, just to make it easier to recognize which wave you are dealing with).

Most of the work of compiling and adapting your waves into a Tone with Wave is done using the panels immediately under the keyboard graphic. Each of these represents a "Split", and each "Split" contains a wave. The parameters in the panel determine how the waves will play in your final Tone with Wave.

The detailed work that creating your sound is done in the lower section of the wave converter. Select which wave is being edited by clicking on the colored bar at the top of each wave panel. For example:

Selecting the first Wave (blue)


Selecting the second Wave (green)


Selecting the third Wave (red)


The color of the highlight bar is different for each wave, and the key range and original note of the wave are shown in the same color.

Let's look at the functions and parameters in each wave panel:



Highlight Bar (green in this example) tells you which panel is active for editing. Each panel has a different color which is matched by the markings on the keyboard graphic (the key range and original note markers)


Wave File shows the name of the wave in use for that split

Click on Open Wav File to load the ".wav" file into that split
(It is possible to load the ".wav" file to drag and drop.)


Key Range sets the lower and upper note limits of the Split. Note that the maximum range is the same as the maximum Midi note range (128 notes) and as shown here goes from C-1 to G9. The key range is much wider even than the 76 Key models. The first Split's starting point is fixed to C-1, But actually the 61 note a keyboard plays from C2 to C7 and the 76 note from E1 to G7.


Original Note is the original note of the wave. This is very important information for Wave Converter or your final sound won't play properly.


Loop Type, Amp Envelope and Filter Envelope are all parameters which determine how the final sound plays. These are explained in detail in 3-2-6 / 3-2-7 and 3-2-8
