Model 158A Dual Sine Sawtooth

Catalyst Audio Model 158A Dual Sine Sawtooth


Dual Sine - Sawtooth Oscillator

The Dual Sine-Sawtooth Generator was inspired by Buchla's Model 158, which was first released as part of the 100 series in the 60's. The module is composed of two oscillators featuring a discrete transistor design. Each audio generator can produce sine or sawtooth waveforms - or anything in between. The pitch ranges from ultrasonic to LFO rates. For modulations, there are exponential CV inputs. In use, the Dual Sine-Sawtooth Generator shines with charming analog sound. Its biggest strengths are frequency and cross modulation. Results can sound very harsh or wet.

  • 1v/octave input (per oscillator)
  • CV input (per oscillator)
