  Work Details  
  Touché combines both analog and digital circuitry in a unique hybrid architecture that develops the advantages of both approaches. User communications and data processing are handled by a self-contained 16 bit computer operating under the direction of FOIL, an advanced interactive music language especially designed for Touché. Easy to learn and use, FOIL applies techniques of man-machine communication that facilitate rapid access to Touchés vocabulary and enable real-time editing and performance. Sound production in Touché is accomplished with a pipelined, multiplexed digital signal generator that assures absolute pitch accuracy (crystal derived) and provides timbral possibilities formerly available only to those with access to major computer installations. Touchés 24 digital oscillators are combined into eight voices that are playable in a variety of polyphonic, split keyboard, and multi-instrument modes. Additionally, Touché contains a specialized hybrid processor that accepts multiple user inputs and simultaneously directs the progress of 64 acoustic parameters, each with a time resolution of 1/1000 of a second. This facility enables precise specification of complex sonic detail and offers expanded possibilities for expressive articulation. Touchés programmability extends far beyond the storage of knob settings - instrument definitions include precise specification of multiple temporal variables as well as minute details of the timbral palette. Up to 32 labeled instrument definitions are instantly accessible; additional definitions may be stored on tape for subsequent retrieval. Touché is flexible - with practically unlimited signal generation capabilities, Touché relies on software to realize its operational characteristics. And that makes updating easy and economical - new versions of FOIL will keep Touché a growing and vital instrument with ever-expanding resources. Accessed 31.05.2007 from
