The Osc Collection
every shade of synth
5 synths · 1 shared interface · 30 impulse responses each

Hover any instrument above to meet it. Each one is sampled from real hardware — vintage analog, 80s classics, digital hybrids, chiptune and eurorack — then wrapped in the same hand-built interface. Once you learn one, you already know the rest.

Who makes this

Built by two people, not a plugin factory.

We're Clay & Kelsy — a queer, woman-owned, two-artist duo. We don't just build these synths; we use them in our music. Every wave shape was sampled in our own studio, every preset played until it felt right.

The music we make has been featured in Music Connection, EARMILK, Naluda, V13 & Apricot — Music Connection even called the Osc Collection “worthy of your attention.”
