VSTi PluginsA VSTi (VST Instrument ) is a VST Plugin that can convert MIDI events to audio. You can select a VSTi by clicking the instrument slot's down arrow. The VSTi plugins appear in the list's 'VSTi and DXi Plugins' section. A VST or VSTi plugin will initially appear in both Effect and Instrument selectors. The first time it is loaded MultitrackStudio determines whether it's an effect and/or an instrument. From then on it will appear in the appropriate selector only. VST Instruments look like VST Plugins. They have an additional Channel Selector. Some VSTi plugins respond to all MIDI channels the same way, in this case the channel setting doesn't matter unless you're recording using the Keyboard Splitter or multiple keyboards. Other plugins, especially the ones providing many different sounds, do always require the correct channel to be specified. VST Instruments respond to all the streams that are in the track's MIDI file. However, in most cases it will be easier to use multiple tracks (each using an instance of the VSTi) instead. If the plugin has more than two outputs an Output button will be available. On clicking this button the Output Mixer window will appear. This mixer mixes the plugin's outputs down to stereo. Tip (Pro Plus edition only): The outputs of a multiple output VSTi plugin can be routed to tracks using sidechaining (see Effect Sidechain Routing). You can use this if you'd rather mix the outputs in the main window rather than the VSTi Output Mixer window. This is especially useful for drum plugins. Using more memory on 64 bit Windows64 bit versions of Windows support over 4 GB of memory. MultitrackStudio, being a 32 bit program, can use only 2 GB. That's usually no problem at all because it's next to impossible for MultitrackStudio to require that much memory. There's one exception: sample-based VSTi plugins. Some of them can use hundreds of megabytes for just one instrument. If you use several of those you'll want to use all the memory your computer can provide.To work around this limitation VSTi plugins can run 'bridged', or 'out-of-process' in computer lingo. Each bridged plugin can access up to 2 GB of memory. To run a plugin bridged you can right-click it in the instrument selector, and check the Run bridged option. From now on, all new instances of the plugin will run bridged. The window title bar of a bridged plugin reads "VST pluging (bridged): name". Bridging plugins has some drawbacks as well: there's some performance overhead, and you may hear glitches while recording them at low ASIO/VistaSound latencies. It's recommended to use bridging only if it really helps (ie. you have 64 bit Windows, at least 4GB of RAM, and VSTi plugins which use huge amounts of memory). You can use the Windows Task Manager to find out how much memory MtStudio.exe is using. If it's less than 2 GB there's no point in bridging plugins. Note: not all VSTi plugins are happy running bridged. Some seem to work fine running one instance, but weird things happen if you add more instances. Some copy protection mechanisms may fail. Some won't work if UAC (User Account Control) is enabled on Windows Vista and newer. Under the hood | ||
