Zyphr is a multi-oscillator synthesizer for designing and prototyping my music. It consists of an envelope, LFO, filter, and effects controls. Zyphr records and saves my music locally. I use keyboard action c to toggle media controls. Hallo Kopter was made with Zyphr, excluding the drums. Installable via add-to-homescreen on smartphones.
c: toggle media controls.o: toggle oscilloscope.
