Erica Synths Modulator II is 35mm deep, skiff friendly, has solid mechanical construction and doesn’t require wiring.
This kit includes all the components needed for the module, including the knobs, power cable, etc.
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.
The Full Kit includes all components needed for the module and Acid/Modulator boards, including ICs, knobs, power cable, etc.
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. A kit comes with 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

An LFO and noise generator.OK build, some tight fits so might not be your best first kit.It’s OK, a pretty basic LFO and noise. Waveforms are unusually jaggy for some reason. And it's a single LFO with little mod capability, there are many better ones with multiple LFOs and more CV ins. This won’t replace anything in my rack.For a complete build and demo, search YouTube for "C.K. builds a Modulator II from Erica Synths, eurorack"
