3.10-- Using WaveWarp with Emagic Logic Audio 4.1

This example was developed with Emagic Logic Audio Platinum 4.1.4 under Windows 98 (2^nd Edition). Compatibility with other versions of the software or operating systems is not guaranteed.

Starting from scratch without WaveWarp or Logic Audio running, carry out the following steps in order:

1. Start Logic Audio. You should be presented with an empty track list as shown in the screenshot in Figure 43.

2. Select "Sample Editor" from the "Audio" menu in the main toolbar, as shown in the screenshot in Figure 44.

This will cause a pop-up message box to appear as shown in the screenshot in Figure 45.

3. Click "Open" in the message box in Figure 45. A file browser will appear via which you may select any stereo WAV file of your choice. For the sake of example, try selecting "wavewarp.wav" from the "Wav\Stereo" sub-directory of the WaveWarp root. The waveform will appear in the sample editor window, as shown in the screenshot in Figure 46.

4. Close the Sample Editor Window (by clicking on the cross in the upper right-hand-side). Open the "Audio Window" via the "Audio" menu in the main toolbar, as shown in the screenshot in Figure 47.

5. The Audio Window will open and will contain the WAV file which has just been loaded (i.e. "Wavewarp.wav" in this example), as shown in the screenshot in Figure 48.

6. Click on the filename label ("Wavewarp" in this example) in the Audio Window and drag it on to the blank area located to the right of the "Audio 1" track in the Arrange Window (i.e. the main Window). This will place the WAV file on the first audio track, as shown in Figure 49.

7. If not already selected, select the WAV file region on track 1 by clicking on it (it will turn black when selected, as shown in Figure 49), then select "Object -> Set Locators by Objects" via the Function menu on the main toolbar, as shown in the screenshot in Figure 50.

8. Click on the upper half of the "ruler" located above the selected WAV file region in the Arrange Window. The section of the "ruler" corresponding to the assigned Loop Locators will turn pink (instead of black), indicating that the Loop Selectors have been set as desired. This is shown in the screenshot in Figure 51. This enables auto-looping around the WAV file (for convenience when auditioning the DirectX effect later).

9. Now double click on the "Audio 1" track label in the Arrange Window. This will open the mixer console ("Environment Window"), as shown in the screenshot in Figure 52.

10. Click and hold the light blue rectangular button located just below the "Inserts" label on tracks 1-2 of the mixer. This will activate a menu from which you can select a DirectX plugin from the list of available effects installed on your computer. Select "WaveWarp Interface Stereo", as illustrated in the screenshot in Figure 53.

11. The blue rectangular button will "light up" with the label "W1 Stereo", as shown in the screenshot in Figure 54.

Figure 54 "Inserts" status display showing "W1 Stereo" which indicates that the WaveWarp Stereo DirectX Interface has been selected as the DirectX plugin for Tracks 1-2 in Logic Audio 4.1.

12. Double-click on this "W1 Stereo" label (single-clicking will have no effect). The WaveWarp DirectX Interface will now open, as shown in the screenshot in Figure 55. Also, by default, WaveWarp will automatically boot-up (unless it is already started) and the Example DrawingBoard entitled "DirectXstereoWelcome.dwb" will automatically be loaded with its Parameter Windows and Description Window open. These windows are also shown in .

This interface is essentially the same as that shown in Figure 27 except for a different "Presets" panel, the layout of which depends on the sequencer (in this case Logic Audio 4.1). Also shown are the Parameter Windows and Description Window for "DirectXstereoWelcome.dwb" which is automatically loaded (unless this option has been suppressed from within WaveWarp's Option menu).

13. To select an Example DrawingBoard for use as a DirectX effect (if "DirectXstereoWelcome.dwb" did not automatically load during the previous step), press the "Browse" button in the WaveWarp DirectX Interface. The browser should (by default) be set to the "ExampleDrawingBoards\DirectX\Stereo" sub-directory of the WaveWarp root (if it is not, then navigate to this location) and select the "DirectXstereoWelcome.dwb" DrawingBoard. WaveWarp will automatically boot-up in the background (if it hasn't already), and the selected DrawingBoard will be enabled as the DirectX plugin. The two parameter windows for this DrawingBoard, namely the "Simple Delay" and the "Decibel Mixer" windows, will appear in the foreground of the main Logic Audio window, as shown in the screenshot in Figure 55. The DrawingBoard Description Window will also open (in non-edit mode). Important note: the WaveWarp application, though running, is hidden from view.

14. Press the "Play" button in Logic Audio, as illustrated in Figure 56. You will hear the WAV file in the Logic Audio track being processed in real-time by the WaveWarp DrawingBoard acting as a DirectX plugin ! Try adjusting the sliders of the "Simple Delay" and the "Decibel Mixer" on-the-fly.

15. Try experimenting with different example DrawingBoards using the "Browse" button in the WaveWarp DirectX interface. As explained in section 3.5.1--, any DrawingBoard can be selected since it will be automatically converted into a DirectX-enabled DrawingBoard (i.e. the appropriate ports will be added). Refer to section 3.5-- for detailed information on manipulating WaveWarp via the DirectX Interface. Once you are familiar with this interface, try "bringing WaveWarp to the front" and changing the architecture of the effect by removing, adding, or changing the components - better still, try building your own DirectX effect from scratch !
