The Beholder is a simple three voice Hexschmidt trigger synth. The Synth has one adjustable-rate LFO in the form of a flashing LED protruding from the top of the synth. One can assign the LFO to either the volume of voice 1, the volume of voice 2, or the volume of the entire synth by "patching" one of the three protruding light sensing tentacles into the LED tube.
