About VST plugins VST (Virtual Studio Technology) is a software instruments and effects plug-in format designed by Steinberg. As from Reason 9.5, VST 2.4 plugins are supported in Reason. VST plugins integrate nicely with the Reason rack: • A VST Plugin is represented by a Plugin Rack Device in the Reason rack. • Cables can be connected on the rear panels of the Plugin Rack Devices, just like on the internal rack devices. • CV signals can be routed like on the internal rack devices. • Plugin Rack Devices are combinable with other Plugin Rack Devices, Rack Extensions and internal devices (see “The Combinator” chapter). • Panel parameters are automatable and remotable. VST compatibility in Reason • Reason 9.5 and later supports the VST 2.4 plugin format. VST 3 plugins are not supported. • Both Windows and Mac VSTs are supported. Since Reason is a 64-bit application, only 64-bit VSTs are supported. Multitimbrality in VSTs is currently not supported - only one sound per VST can be played back at a time. If you are using a multitimbral VST it will only receive on MIDI Channel 1.
