Erica Synths has introduced new DIY kits which they describe as fully redesigned, skiff friendly and even more adapted for modular functionality – great sounding 84HP two-VCO modular system with 53 patch points that go well beyond classical monosynths. Here's the details in the company's own words...
Key modules are Polivoks-inspired, but this is not just a Polivoks clone. We have introduced numerous innovative solutions in each module to make it more versatile and to expand the functionality of the entire system.
DIY module system includes:
DIY MIDI-CV emulates classical monophonic and duophonic synth behaviour.
DIY Modulator essentially is LFO with simultaneous triangle and square wave outputs, clockable S&H with external CV input and noise source.
DIY Polivoks-inspired VCO with simultaneous triangle, ramp and pulse wave outputs, sync and PWM CV inputs. In VCO's exponential converter we use the original matched transistor IC that was used in Polivoks.
DIY Mixer is simple, straight-forward audio mixer an essential part of any modular setup.
DIY Polivoks VCF is famous for its' crazy resonance sweeps and deep, bassy
sound, which makes it ideal for acid basslines. A kit comes with two K140UD12
opamps that were used in the original Polivoks.
DIY Polivoks-inspired looping ADSR Envelope generator with gate delay,
direct and inverted envelope outputs.
DIY Polivoks-inspired VCA - two differential opamp-based VCAs in series each
for LFO and ADSR control over signal amplitude independently; it can be used
as dual VCA, as well. Kit comes with two K118UD1 differential opamp ICs.
DIY Output module allows you to interface modular system with external gear
via 3,5mm stereo jack and monitor compositions on headphones.
To complete the System, we have added:
One row 84HP skiff case
External, universal PSU module
Horizontal wooden side panels
