The real-time adjustable acoustic control
The Kispest organ is supplied with a real-time acoustic control feature that can be used with the INSP:DEC Surround Customizer VST plugin. It has a different documentation also provided with the Kispest Pipe Organ Samples, this section covers how to optimally set up Hauptwerk* to make this feature work.
To be able to use the real-time acoustic control Hauptwerk* should output 3 or 4 independent channels for each stop. There is a separate ODF file that supports this.
For a 2-dimensional full control, 3 channels are needed, for a 3-dimensional control 4 channels are required. 3-dimensional control is available in the Extended Edition of the Kispest Pipe Organ Samples.
Please note that this feature works currently (as of Hauptwerk* version 3.23) only in Windows. For Mac compatibility, please refer to updates on the Inspired Acoustics website.
The step-by-step configuration to allow the real-time acoustic spatial control is – as of Hauptwerk* version 3 – as follows:
- Set up 3 or 4 independent Audio Output Groups in Hauptwerk*. To do this, go to the General Settings menu and select Audio Output Groups. Here press Insert and give a desired name to each output. Insert outputs so that 3 or 4 outputs will be present (add 4 output groups if you use the Extended Edition of the Kispest Pipe Organ Samples or 3 otherwise).
- Assign audio routing in Hauptwerk*. To do this, go to General Settings menu and select Audio Outputs. Press Insert, give a name to this output and click the Routing tab on the top right side. Here select one of the Audio output groups that you have created in the previous step. Repeat this step for each audio output groups so that all of them will be assigned to a different Audio Output that you can create here.
- Load the appropriate ODF file of the Kispest Organ and route each output in their coming order. To do this: select all ranks that are named starting ‘Base:’ and select the destination output group on the right side to your first output that you created in the previous step. Assign ranks named ‘Depth’ and ‘Width’ the same way to the other two different outputs. If you have the Extended Edition, assign ‘Height’ to the fourth output group.
- Wire the loaded organ into the VST Plugin. Load the organ and then connect the outputs of Hauptwerk* to the inputs of the Surround Customizer VST Plugin. To do this please refer to your audio host’s User’s Manual since this step depends on the host you are using.
IMPORTANT: In the VSTi version of the current Hauptwerk*, the outputs are always 2 channel stereo outputs. This means that although you have set to load a mono rank (e.g. Base: 0_001 Principal 16’) and route it to Hauptwerk*’s first VST output, the same sound will appear on the 2nd channel of Hauptwerk* as well. So Hauptwerk* VSTi outputs channel 1-2, 3-4, 5-6 and 7-8 will have the same audio content respectively for each pair. This means that you will need to connect every second set of Hauptwerk*’s outputs to the input of the customizer plugin. So Hauptwerk*’s output channel 1 OR 2 should go into the Surround customizer plugins’s Input channel 1. Hauptwerk*’s output 3 OR 4 should go into the plugin’s Input channel 2 and so on. Make sure that you do this interleaving when connecting Hauptwerk* to the customizer Plugin, otherwise the customization effect will not work as intended.
