| Robert Olsen and Joshua Stockton would like to create a rebirth/reimagining of the classic analog synthesizer. It will be similar to previous modular synthesizers, but will instead have a different user interface. Regarding project 1 from Spring 17, our synthesizer is different in that it is not a sequencer. Each wave is generated by the activation of a momentary switch, feeding off of a chain of resistors (or other form of regulating the VCO), each node corresponding to a different frequency of note to be played. Robert Olsen and Joshua Stockton would like to create a rebirth/reimagining of the classic analog synthesizer. It will be similar to previous modular synthesizers, but will instead have a different user interface. Regarding project 1 from Spring 17, our synthesizer is different in that it is not a sequencer. Each wave is generated by the activation of a momentary switch, feeding off of a chain of resistors (or other form of regulating the VCO), each node corresponding to a different frequency of note to be played. Components of our project will contain, but are not limited to, a VCO (pair of op amps configured with resistors and capacitors depending on which wave is being produced) , amplifiers (op amps again), filters to improve sound quality (at the very least, a low pass filter to eliminate very high frequencies and noise), an arpeggiator (for this, we would use a microcontroller to automatically scroll through the notes pressed in an ascending order), and a unique user interface. Our proposed user interface is a grid of momentary switches (probably 24x3 in order to get two octaves of notes with three waveforms each) where each column corresponds to a unique pitch, and each row corresponds to a unique waveform (square, sine, and triangle waves). This level of user interactivity hasn’t been released before and could, for example, serve as a learning tool to teach new players or audio engineers the different qualities of a sound on a basic level. Included will also be a potentiometer for both volume and pitch shifting as well as a rotary switch to switch between octaves easily. |
