Description
Theremin module for generating a variable control voltage by approaching/removing hand to/from an antenna. The distance range is about 30 cm.
Additionally the module is equipped with a Gate output with adjustable threshold level.
To simulate the original Theremin two A-178, a VCO (e.g. A-110) and a linear VCA (e.g. A-130 or A-132) are required. But of course the A-178 can be used to control other functions in the A-100 (e.g. filter frequency, modulation depth and/or speed, tempo, attack/decay time and so on).
The CV output voltage of the A-178 can range - according to the setting of the front panel controls - from -10V...+10V. The gate output switches from 0V to about +10V.
