This short experiment was produced by programming a custom formant sequence into the infamous Yamaha FS1R. This is not possible to do with the unit alone, but there are some great tools that make it possible that I’ll discuss an upcoming article. A formant sequence essentially modulates the formant shaping operators on the FS1R modeled after the spectra from am audio signal. This patch repurposes a vocal track from my project Voice Lessons as the formant sequence.
