INSTRUMENT SELECTION This facility provides immediate access to the 32 instrument definitions that reside in Touché's memory. Each of these instruments relates, in arbitrarily complex or subtle ways, performance gestures to the various acoustic responses that comprise Touché's vocabulary. Any two instruments may be played simultaneously; selection is accomplished by touching the select button followed by two digits from the data entry array. DATA ENTRY Touché is equipped with a sophisticated interactive music language (FOIL) that permits the user to readily create or alter instrument definitions. This data entry section is the primary input to FOIL; the output is via a standard video monitor. Note that information can be entered either digitally or via knob settings; and that the effect of changing data is immediately perceivable - this a real time, interactive editing facility. FINE TUNING Touché, with its crystal controlled digital oscillators, has perfect pitch. There's no drift, no adjustments, no autotune. This fine tuning knob is provided to facilitate playing in ensemble with other instruments.

CABINET Hand crafted of select Koa wood, the beauty of Touché's housing reflects the pride and care that go into its construction. The hinged top is your invitation to peer inside - few instruments are built like Touché. OCTAVE REGISTRATION Transposition controls and indicators for each of two instruments extend Touché's range to eight octaves. PARAMETER ARTICULATION Touché's unusual sonic range is realized with a specialized digital oscillator in which a number of parameters can be specified and stored as part of instrument definitions. Occasionally, in performance situations it is desirable to have immediate access to these variables - hence the inclusion of this section. Rear panel inputs allow external voltage control or foot pedal control of the oscillator parameters and front panel knobs allow static offsetting of these parameters. The net results are displayed by light emitting diodes, and can be applied to either or both of the two current instrument definitions.

OUTPUT AMPLITUDE Touché is designed to drive four channels of power amplification, with speakers clustered, spread across the stage, or surrounding a room. Special phasing circuits provide unusual depth and imaging in the resultant acoustic field. This master volume controls the four channel output as well as stereo and monophonic submixes. A headset output, with separate balance and level controls, is on the rear panel. MODE In the edit mode, the 3 axis tablet becomes the means for efficient access to stored instrument definitions, which are displayed on a TV or video monitor. In the play mode, the tablet resumes its role as a performance input, and editing functions are inhibited. The reset button provides fast access to an initial state, with all modes and offsets normalized and instruments 1 and 2 selected for playing TIME SCALING In Touché, complex time varying functions can be specified for each of six different variables. This knob enables the compression or expansion of these temporal functions without disturbing ratios or pitches. MANUAL PARTITIONING With Touché, two instrument definitions can be selected and performed simultaneously. The normal mode of playing two instruments is with each key activating both voices. The fixed partitioning mode assigns instrument A to the lower half and instrument B to the upper half of the keyboard. The adaptive mode assigns instrument A to the left hand; B to the right. Reverse interchanges instruments A and B.

PROGRAMMED STIMULI The music language (FOIL) used to define Touché's instrumental repertoire includes provision for selectively activating or modifying certain processes. These touch switches, with self-contained status indicators, provide the musician with the requisite controls. Additional such programmed stimuli, originating from foot pedals or external voltages may be applied to back panel inputs. TAPE CONTROL With Touché's facility for tape storage and retrieval your library of instrumental resources knows to bounds. 32 instruments are just a touch away - hundreds more can be stored on a single cassette. OUTPUT MIX AND PANNING The relative loudness of the two selected instruments is determined here; automatic panning enables the gradual transformation of one instrument into another. THREE-AXIS TABLET Touch the tablet and Touché responds with note bending, vibrato, timbre shadings, in any combination and to any degree. With no moving parts and a variety of software controlled modes, this solid state joystick for exceeds the capabilities of wheels and ribbons. KEYBOARD A specialized digital keyboard processor provides fast, accurate and musically logical polyphonic response; silver contacts and double buss switching assure long-term reliability. This keyboard features pressure sensitivity - any combination of Touché's variables can be programmed to respond to the dynamics of playing.
