The Benjolin V2 by After Later Audio is a successful adaptation of the obscure oscillator and synth voice circuit designed by Rob Hordijk. In detail, the module consists of two analogue oscillators with triangle and square, a multimode filter with parallel tappable filter characteristics lowpass,
The two analogue oscillators can be modulated internally by the Rungler and by an external control voltage. If you are looking for a (dual) oscillator with precise
The Rungler itself is an 8/16-stage shift register that gets its data input from oscillator 1 and its clock input from oscillator 2. The output of the shift register is then fed into a simple DA converter which produces a stepped voltage pattern of variable length and depth. This Rungler wave is then fed back into the oscillators and filtered via the attenuators, creating a complex interference system that gives the Benjolin that unique, aleatoric character. Sonically, the Benjolin V2 moves between classic analogue sounds, noise-like sounds, Atari Punk Console, 8-bit rattle and machine hall.
