If you are reading this, most probably, you are about to build Erica
Synths DIY Modulator. This module is 35mm deep, skiff friendly,
has solid mechanical construction and doesn't require wiring.
The Modulator essentially is 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.
Latest provides perfect, full spectrum white noise.
The DIY Envelope kit comes in three versions:
1) 3 PCBs + S&H chip + connectors,
2) 3 PCBs+ S&H chip + connectors + panel,
3) Full kit.

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 rare, high quality S&H chip
S&H CV and clock inputs

SPECIFICATIONS:

• LFO output amplitude
• LFO frequency range
• Noise output level
• S&H CV input level
• Panel width
• Module depth
• Power consumption
