Teensy Powered Synth Drone Pedal using Soundfonts


New member
Hi everyone!

I've been experimenting with Teensy for a few years now, and I'm excited to share my latest project with you.

I built a drone synth pedal using a Teensy 4.1 with the audio board. The forums here were an amazing repository of information, and I want to offer a huge thanks to
Kris Kasprzak for creating a great library for slider control, as well as an in depth tutorial on it's usage.

I also want to thank manicken for his soundfont decoder for the Teensy 4.1.

I've linked and credited everyone both on my github page as well as in the description of the video I have up on YouTube.


Here is the Video:

Thanks so much!

My first major Teensy project was "The AutoBass" which is a MIDI controller that allows you to step on notes and play full chords,
