In a nutshell, synths create sound, whereas controllers manipulate sound and act as a remote for sound since they do not produce anything of their own.

That’s the basic difference between MIDI controllers and synthesizers.Fast preset sorting to find your sound quickly: by Instrument, by Type (Bass, Pads, Leads…), by Characteristics (long, bright, dark …), etc.All presets are carefully selected from the Arturia V Collection.Includes Analog Lab with 5000 synth sounds.
