PlugIn Menu Figure 37: PlugIn Menu This menu is only visible if a PlugIn window is currently selected (main, edit, parameter, MIDI Parameter, or info window); more on these later in the “Toolbar” section on page 65. Right-clicking on one of the PlugIn windows (except for the Edit window) shows the same menu as a popup menu. Window This sub-menu lets you select (or open, if it isn’t opened yet) one of the possible windows of the PlugIn. Information on most of them can be found in the “Toolbar” section on page 65. The following sub-menu entries deserve special treatment, however…: Configure This sub-menu entry can only be selected if it makes sense, i.e., if the PlugIn requires any of the settings that can be configured on the following window: Figure 38: PlugIn Configuration Window The following settings can be changed here, if possible: 36
Auto-Stereo This check box can only be selected when the current PlugIn has only one output channel. If checked, VSTHost automatically expands the PlugIn’s output to 2 identical pseudo-stereo outputs. Double Precision Audio This check box can only be selected for PlugIns that implement this feature. In the current version, this is mainly usable for testing PlugIns that support processDoubleReplacing() for audio processing. In this mode, VSTHost passes audio to the PlugIn in double precision format (the much-hyped “64 bit audio processing!!!1” �). This, however, doesn’t mean that the output sounds “better” - VSTHost still uses 32 bit audio processing internally; it just converts the samples to 64 bit before calling the PlugIn and converts the result back. So, all you get is a little performance degradation; that’s why I said it’s mainly for testing purposes. But then... if you're using a lot of PlugIns that support double-precision audio, and you want to create chains of them, the continuous conversion between 32- and 64-bit audio would cause more of a performance degradation than running the whole chain with 64-bit double precision audio. Starting with V1.45, VSTHost is also available in a 64-bit version (that's 64-bit audio, not 64-bit code; the code is still 32-bit... we live in interesting times ) that can be separately downloaded from the web site mentioned on page 2 of this document. This version uses 64-bit signal processing internally, which means that: 1. all buffers are twice as big as in the 32-bit version; each and every operation needs to move twice as many bytes around; 2. if a PlugIn does not support 64-bit audio processing, VSTHost now has to convert all buffers to 32-bit before and after they are passed through the PlugIn … in short, it's slower and bigger than the 32-bit version. While the overall sound quality might be a little bit better if 64-bit audio processing is used, I sincerely doubt that anyone can hear this. VSTHost is not meant to be the main vehicle of a mastering studio, where the additional quality might make a difference. Well, it's your decision... a contemporary highend machine surely has no problem with this version. Speaker Configuration If the PlugIn supports setting the speaker configuration, and thus the usable audio channels, you can configure the PlugIn's input and output speaker configuration here. MIDI Parameters This menu entry will probably get a better name in the next version... it's too similar to “MIDI -> Parameter” below... Selecting this menu entry opens a window that allows to configure the PlugIn's MIDI properties. 37
