Pro-Osc — a vintage-era analog synth, sampled into a modern instrument
Pro-Osc is built from the raw oscillators of a Curtis-filtered vintage analog synth, then wrapped in a hand-drawn interface. Cinematic warmth that fills the room, across 83 handcrafted presets with no filler — all performable from the mod wheel. Part of the Osc Collection by Clay and Kelsy Instruments.

What's under the hood
- Three oscillators, 14 wave shapes each — sampled from a Curtis-filtered vintage analog synth, stacked three at a time, with per-oscillator pitch and pan.
- 30 convolution spaces built in — 15 custom reverbs and 15 eurorack FX impulse responses.
- Note-triggered stepped sequencer — swaps the loaded wave shape per note to bring melodies and chords to life.
- Cut-Off LFO and mod-wheel command center — a dedicated filter LFO plus a control center that maps many parameters to your mod wheel at once.
- Vibrato, glide, slop, and spread — plus full NKS support for Maschine and Komplete Kontrol.
