Virtual String Machine®


VSM – The world’s greatest vintage string ensembles wrapped into an intuitive synthesiser user interface

    The Virtual String Machine v3 (VSM) is an intuitive yet highly powerful string machine synthesiser and contains a wealth of sounds from a small mountain of classic and rare string machines.
    VSM comes with 1000+ patches yet enables you to craft your own unique strings from the 208 individual sets of meticulously sampled machines helping confirm VSM as the go-to instrument for this wonderful family of instruments.


A British invention

    The modern, polyphonic string synthesizer was invented in 1970 by Ken Freeman, a British keyboard player and engineer who discovered that if you layered a note with another detuned and slightly modulated version of itself, a pleasant ‘chorused’ sound resulted.
    Even though Ken’s invention wasn’t the first instrument of this genre to be commercially released (That honor fell to the Eminent® organ company with their 310 Unique organ) there’s little doubt that Ken’s vision contributed immeasurably to electronic music over the next few decades in the guise of over 100+ different models that followed from a huge variety of manufacturers.

Artist's Opinion

This is Retro Repro at its best—informed, sensitive, detailed, technologically extended— and best of all a new, very useful electronic instrument in its own right.

21 String Machines in 1 intuitive instrument

    The VSM is an intuitive but highly powerful Virtual String Machine which affords the user many of the sounds from this genre of instrument, and contains a wealth of sounds from a small mountain of classic and rare string machines.

Create your own hybrid sounds

    With the sheer amount of instruments captured within the VSM, its simplicity itself to recreate those golden string machine tones from yesteryear. However, with the VSM’s comprehensive, yet intuitive feature-set, plus a two-layer option it’s now possible to create your own hybrid instruments taking these sublime vintage tones into hitherto unchartered territory.
    VSM – The Go-To String Machine Instrument.
