Artist's Opinion

The M-Tron Pro and it’s expansion packs are completely believable and as authentic as they come. I’ve used these on many records and on tour  – I couldn’t do without them in my arsenal of sounds

Dave Brinkworth

From the Optigan to the OptiTron

Originally manufactured by toy maker Mattel®, the Optigan was an attempt to break into the burgeoning ‘home entertainment’ market of the 1970s.

The Optigan used LP sized plastic discs on which sounds, backing tracks and effects were stored and these were read by an optical sensor on the instrument itself. The idea was simple. Pushing a button gave you a backing track in a variety of keys and you then played the keyboard to accompany these backings.

Although there were several different Optigan models available, ranging from the single speaker 34001 to the ‘Stereophonic’ & ‘reverb’ laden 35011, the operating principle of the instrument remained the same throughout its existence.

The Optigan came with a set of discs that included; Big Organ & Drums, Pop Piano Plus Guitar, Latin Fever and Guitar in 3/4 Time. Additional discs could then be purchased and, stylistically, these ranged from bona-fide classics such as Singing Rhythms & Classic Guitar (the latter used to great effect by Jon Brion on the film soundtrack to Eternal Sunshine of the Spotless Mind) to the toe-curling Nashville Country and truly epic Romantic Strings.

It’s fair to say that the lo-fi sound and general poor build quality never really captured the public’s imagination and subsequently a large percentage of Optigans either ended up as landfill or simply being sold on for a pittance.

Steve Hackett had made use of the Big Band disc on his Sentimental Institution track on the 1980 Defector album, but by-and-large in the UK the Optigan was unknown.

Indeed, our love affair with the instrument only started when we heard one in the USA at the turn of the century. There was something about the instrument’s backing tracks that took us back to our teenage days of the 1970s. The same instant nostalgia that the M-Tron Pro rhythms imparted and we knew we had to acquire one somehow.

Our friend Scanner contacted us to say that the UK based band Coil not only had an instrument but a massive collection of discs too. Several phone calls later, Coil’s Peter Christopherson and Jhonn Balance invited us to their studio to begin the recording process and we jumped at the opportunity.
