Erica Synths are famous for their Black and Pico range of Eurorack modules. They are also fans of the DIY Modular community and have made a number of kits available for the eager purist to get their soldering iron into. The DIY Synth Voice is the latest kit to emerge from Erica Synths and it’s a fully fledged semi-modular mono-synth.
DIY Synth Voice
Once constructed you should be the proud owner of a versatile single oscillator mono-synth. There’s a mixture of digital and analogue technology going on. The VCO, envelope generators and LFO’s are all digital running through analogue filters inspired by the Black Polivoks VCF. Other features include a white noise generator, external input, audio mixer, envelope and LFO looping, tap tempo and LFO sync, sub oscillator and auto calibration for better tuning.
The kit is not for the faint hearted. There are three different versions. The first one comes with the PCB’s drilled and ready plus the IC’s to plug in. The second kit also comes with the front panel, which will be very handy. Neither come with any other components such as resistors, capacitors, potentiometers or knobs. However the manual comes with a big long bill of materials to take along to Maplin or Radio Spares. Alternatively they also do a third kit that has absolutely everything included except the many hours you’ll need to assemble it.
I am totally into the idea of DIY synthesis modules and I wish it’s the sort of thing I had time for. If you really want to get under the skin of sound generation and music technology electronics then this is the way to go.
PCBs + ICs (MCU board, 2 x K140UD12 op-amps, PCB connectors) – €60
PCBs + ICs (MCU board, 2 x K140UD12 op-amps, PCB connectors) plus front panel – €90
