Music Developments Syne v1.4.1 (win/macOS)

Syne is a fully modular additive synthesizer with a beautiful analog sound and extreme flexibility with microtuning and MPE support.

Syne is a new, fully modular additive synthesizer capable of rendering more than 40000 partials realtime on a recent CPU (=powerful) while having full control over each partial (=flexible). This allows making complex sounds that are not possible with other types of synthesis.
