The native VSampler VST instrument is an interface to VSampler which is compatible with the Cubase VST instrument interface 2.0 (Cubase 3.7 or later). Other sequencer programs (e.g. Logic Audio) support the VST instrument interface as well, but the following examples refer to Cubase VST, the activation of the VSampler VST instrument may differ in other programs.
The VSampler VST instrument is part of the Virtual Sampler 'Professional' version.
The native VST instrument enables sample-exact playback of sampler sounds within a MIDI-track of a VST song. That means:
The VSampler VST instrument is 16 part multitimbral and is almost identical to the stand-alone version of VSampler in functions and handling.
The stand-alone version makes it possible to use VSampler through the VMIDI port from all sequencers, even those without support for the VST 2.0 interface. Furthermore it allows to create and test sounds and soundbanks outside of a sequencer.
And it offers a solution for a global disadvantage of all VST instruments: without a low latency ASIO driver for your soundcard playing the VST instrument live (via keyboard) is not possible, you will most probably notice an audible delay between pressing the key and the start of the sound. This does NOT apply for MIDI tracks within Cubase VST, they are played absolutely timing-precise. For users of VSampler without ASIO driver we recommend the following procedure:
The VSampler VST instrument in Cubase VST needs to be called from the menu Audio|VST Instruments. After selecting VSampler you need to activate it. The button Edit opens the user interface of the instrument.
To output a multi (MIDI) track through the VST mixer channel of your choice, you need to specify this channel at the 'Multi' page in the "Output" column of the multi-grid.
There's a maximum of 16 assignable VST channels (see Audio Preferences). Those channels appear in Cubase VST's mixer window as channel inserts. So every VSampler multi-channel can be controlled and mixed in Cubase VST separately. Mapping multiple VSampler multi-channels to one VST channel is possible too. In this case VSampler mixes the sound data of those multi-channels. This may save CPU power, but you can't control them separately in Cubase VST then, but only as sum (changing the volume level or other multi-settings within VSampler is still possible, of course).
