Hybrid analog-digital modular Synthesizer

Timeline

Status: Active

Description

We are making a modular electronic synthesizer capable of generating, shaping, and amplifying waveforms to make different sounds. Our device will be able to interface a midi keyboard or sequencer for the user to play, and the user will also be able to control the shape of the wave using the modules. The Oscillator is digital and made with a Raspberry Pi which is able to generate different types of waveforms specified by the user (triangle, sine, sawtooth, supersaw, square). The digital signal will be converted to an analog one through an R-2R resistor network. This is then connected to an analog voltage-controlled filter that will change the waveform by filtering out specific frequencies. Finally, a voltage-controlled amplifier will take the signal from the filter to amplify it and relay it to a speaker to play the final sound. We will utilize PCBs as well as dead-bug electronic designs in different parts of the project. The project

will use the Eurorack standard, which specifies the power supply needed, the size of the patching cables, and a few other things. The synth will be enclosed in a mixture of 3D printed plastic filament and laser-cut acrylic (in order to see dead bug module). Upon completion of the project, the user will be able to play the midi keyboard or sequencer and turn knobs on the modules to change the sound. Completely new and unique sounds will be made.
