VSTHost is a program to run VST PlugIns. In contrast to the big programs (Cubase, Nuendo, Logic
come to mind), it is not a full-fledged giant sequencer package that needs many seconds just to come
up to a point where it can say “Hello”. It’s relatively small, and hopefully will stay so, and it
only
runs
PlugIns. No sequencing (well, it can play back simple audio and MIDI files), no elaborate recording
facilities (although it does have a simple multitrack recorder built in). To make up for that, you can
define very complex PlugIn setups and switch between them easily.
