2 Compression Modes
Mode 01
⚡ Modern Mode
Retro Sta-Level Gold Edition
Emulates the definitive modern Retro Sta-Level Gold Edition — a deluxe, all-tube, made-in-USA recreation of the classic 1956 design. This is the go-to mode for the full, polished, euphonic tube compression character that professionals use on vocals, drums, and bus processing on Mac — punchy, musical, and larger than life.
Mode 02
📻 Vintage Mode
1956 Gates Sta-Level — Modded by Phil Moore
Emulates an original 1956 Gates Sta-Level from Devin Powers’ personal collection — specifically modded by Phil Moore of Retro Instruments to offer the full feature set of the Retro Sta-Level. Delivers a vintage, mid-focused, harmonically rich alternate voicing — rawer, more characterful, and deeply vintage-sounding on macOS.
