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.
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
Each bridged plugin appears in the Windows Task Manager as "MtStudioVSTServer.exe".
8.6 DXi Plugins
A DXi (DirectX Instrument) is a DX Plugin that can convert MIDI events to audio. You can select a DXi by
clicking the instrument slot's down arrow. The DXi plugins appear in the list's 'VSTi and DXi Plugins'
section.
DX Instruments look like DX Plugins. They have an additional Channel Selector. Some DXi 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.
DX 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 DX Instrument) instead.
If a plugin is available in both VSTi and DXi format it is recommended to use the VSTi plugin as they have
less overhead and better timing accuracy.
