Shmøergh Funk Live One — 6 voice paraphonic synthesizer

Shmøergh Funk Live One is a 6 voice (mostly) digitally controlled paraphonic analog synthesizer. Its purposefully built with limitations so it's great for live performances with quick changes in settings without presets or menu diving. It has a lot of simple but effective ways to modulate the filter cutoff which makes it great for funk performances. Because of its simplicity it's also cool to get started with synthesis.
