Cromina String Machine is a physical modeling recreation of the electronic strings sound of the '60s and '70s. Solina, Crumar and Logan were the names which made it possible for bands to bring a string orchestra on stage or into the studio - the sound of these electronic keyboards featured on many songs of this era.

WOK says that the sound-wise peculiarities of the frequency divider circuit and the BBD modulation section can not be successfully recreated by sampling, so they developed a plug-in with the main emphasis on the reproduction of this typical influence on the sound. Though the drawback is a higher CPU load, it gives a much better reproduction of the original sound.

Although this plug-in has its focus on the typical Solina sound (including a phaser and delay effect), it can produce a wide range of typical sounds by using the integrated equalizer, vibrato, envelope variations (including a piano envelope) and other tuning controls.
