Examining The Wording Of Digital Synthesizer Presets To Help Novice Producers, Nicholas O'Toole
Examining The Wording Of Digital Synthesizer Presets To Help Novice Producers, Nicholas O'Toole
Honors Theses
My research looks into the use of ”presets” in digital synthesizers, which alter the timbre (quality) of the synthesizer’s sound by loading in pre-selected configurations of settings. My study compares imagery- based and feelings-based preset names – for example, Cloud City Keys and Mellow lead, respectively – in an attempt to see which better predicts the sound it represents. Through my results, I will then explain how the wording of these preset names affected my subjects’ perception of certain sounds. The results I found lead me to believe that imagery-based preset names could be representative of their respective presets’ sounds.

Art To Influence Creativity In Algorithmic Composition, Tyler Braithwaite
Honors Theses
Advances in Recurrent Neural Network (RNN) techniques have caused an explosion of problems posed that revolve around the mass analysis and generation of sequential data, including symbolic music. Building off the work of Nathaniel Patterson’s Musical Autocomplete: An LSTM Approach, we extend this problem of continuing a composition by examining the creative impact that injecting latent-space encoded image data, specifically fine art from the WikiArt Dataset, has on the musical output of RNN architectures designed for autocomplete. For comparison purposes with Patterson, we will also be using a corpus of Erik Satie’s piano music for training, validation, and testing.
