Hello all,
I just wanted to share a project that I completed a while back with the help of a lot of people on this forum. (Thank you!) It's a Teensy synth that has an experimental interface-- instead of a chromatic keyboard like most synths, the pitch of the notes is controlled by sliders. This allows you to play chords and then kind of slowly bend them into other chords. It's a little bit like a pedal steel guitar, where a lot of the "sound" of the instrument comes from the note bends. Kinda creepy and ethereal.
Here are a couple pictures, a video, a github link, and a couple tracks that I played the instrument on.
I've been thinking about creating a couple more iterations of this project, and I had a few questions in case anyone would be willing to give me their feedback/opinions.
1. What is the ideal, lowest noise, way to power a teensy synth? This project has a 9V power input with a 5V regulator circuit. Could I get away with powering something like this just through the USB 5V bus? Are there implications for how much audio noise might come with any given solution?
2. I do have a lot of high-pitched noise on the output of the instrument. What might be the common culprits of an issue like that? Are there ways I could reduce that? Would it make sense to throw some kind of analog low-pass filter on the output of the instrument?
3. I'd like to try to do an iteration of this project with more potentiometer inputs. Is there a go to analog MUX for this type of thing that pairs well and easily with the teensy?
Thanks so much for reading this and for any advice anyone might have.
