A-100 Touch Sensor Keyboard / Sequencer

Technical specifications

25 touch sensitive keys (no moving parts, each key reacts to touching with the finger)
separate pressure sensor under each key
control (rotary potentiometer) for each key (maybe even an additional row of potentiometers, but this would increase the price considerably)
gate output with LED display for each key
2 CV outputs for each key
CV1: controlled by the corresponding potentiometer (i.e. 25-fold CV source)
CV2: controlled by corresponding key pressure (i.e. 25-fold gate/trigger source)
common outputs in keyboard mode (probably at the rear panel):
gate
pitch CV (i.e. the "normal" keyboard CV with 1V/octave)
CV controlled by potentiometers
CV controlled by key pressure
common outputs in analog sequencer mode (probably at the rear panel):
gate
CV controlled by potentiometers (quantized in semitones)
CV controlled by potentiometers (not quantized)
CV controlled by key pressure
different sequencer modes:
turning on/off the active steps by touching the keys in toggle mode
only steps with keys touched at the moment are active
only steps between two keys touched at the moment are active
.... and maybe some more
Start and Stop button for sequencer mode
internal clock for sequencer mode (probably control #25)
ext. Clock, Start and Stop inputs for sequencer (and possibly arpeggiator) mode
desktop/19" metal case (can be used as desktop keyboard or mounted in an 19" case e.g. below the A-100 system)
possibly duo-phonic (i.e. 2 CV and gate outputs for controlling 2 voices)
possibly MIDI output (potentiometers may transmit 25 MIDI controllers in keyboard mode)
possibly additional 3 digit LED-display
