It works perfectly for retro 80s style productions, and therefore synthwave. Kern is a personal favorite and go-to of mine. With Kern, you get MIDI Learn, two user panels, 32 voice polyphony including portamento, two band-limited oscillators including Hard Sync, two types of four-pole zero-delay feedback lowpass filters, two envelopes (one LFO), chorus, and double precision audio processing. It is fully compatible with MIDI keyboard controllers, as you would expect, and its CPU consumption is notably low. Full Bucket Music’s Kern is a polyphonic software synthesizer designed with Windows and Mac OS in mind.
