The Beilfuss Step Synthesizer


One of the first images of the Beilfuss Step Synthesizer – a new synth design from the Beilfuss Synthesizer Company, described as “the world’s first step synthesizer”:


This thought-through system is the optimization of flexibility with controllability for keyboard. The step synthesizer brings new, never before heard, electronic sounds to music.

Unlike any analog or digital synthesizer’s controls, the patented tone control consists of sixteen steps simply outlining the waveform as set by the Signal Controls you see at the left of the control panel. Similarly, the envelope and filter contour transients and their time intervals are also set by the Signal Controls for rhythms or extended notes. You may easily add prompted, parallel voicings, combining settings of both sides for complex notes.There are 32 controls and 142 pushbuttons for direct programming. Dedicated LED pushbuttons always read out their side of the full eight octave, split keyboard. Five octaves of transposition are possible.
