The good news is that vArranger has a VST Host, that can load and play, up to 16 VST Instruments. Some have a very high sound quality, that can surpass their hardware alternatives, while others are not so good. Nowadays, there are large numbers of third-party companies, that are producing VST instrument plug-ins. So basically, a VSTi is a realtime software synthesizer.
It allows third-party developers to produce real-time effects modules (VST or VST FX), or synth engines that are called VST Instruments (VSTi), that could 'plug in' to the host application. The VST (Virtual Studio Technology) system was developed by Steinberg, to enable a complete studio to be created in software.
