Erica Synths Modulator II is 35mm deep, skiff friendly, has solid mechanical construction and doesn’t require wiring.

The circuit comes with two logic boards, the Acid Noise and Modulator Noise boards. Only one can be used at a time, but they are on pin headers on the back of the module, so they can be easily swapped.  The zener-based Acid Noise board generates full spectrum white noise, while transistor-based Modulator Noise generator has a different tone. Just make sure the orientation is correct: the silkscreen text should be facing the same direction as the front panel.

All PCBs, including Acid Noise and Modulator Noise boards, panel, and the 1100CK2 IC (hard to source)

Features:

  • LFO with triangle and pulse wave outputs
     
  • Choice of transistor-based or Zener diode-based noise generator for massive, full spectrum white noise
     
  • S&H circuit based on high-quality 1100CK2 S&H chip
     
  • S&H CV and clock inputs

The Modulator II essentially is an LFO with simultaneous triangle and square wave outputs, clockable S&H with external CV input and noise source. Includes two versions of noise generator – simple, transistor-based and more complex Zener diode-based one. The latest provides perfect, full spectrum white noise.

Technical specifications:

LFO output amplitude:     -5V…+5V

LFO frequency range:      0.1…20Hz (configurable)

Noise output level:            10Vptp

S&H CV input level:           up to 20Vptp

Panel width:                       8HP

Module depth:                   35mm

Power consumption:        27mA@+12V, 22mA@-12V
