Hi!
Elegance in design is a set of choices of what not to include - and I think Nonlinear Labs achieved this goal with C15's synth engine. In this video I take a look how you can start with two simple sine waves, and take them quite a long way with relatively few components.
C15 isn't cheap, mainly because it's hand-made in Germany in small quantities, but if you'd like to explore it's synth engine, the company developed the software instrument Kontour in collaboration with Native Instruments, with a very similar engine and sounds.
Attached to this post is an MP3 download of over 20 minutes where I play its presets - feel free to download, play and chill...
All my best,
