Vacuum Pro

Vacuum Pro by AIR Music Technology is a polyphonic analog-modeling synthesizer built for warm basses, gritty leads, spacious pads, and experimental effects. Its vacuum tube circuit modeling adds saturation and character throughout the signal path, making it a strong fit for producers chasing 70s and 80s synth textures. Two independent synth parts can be stacked, split, or layered, with four oscillators providing plenty of scope for detuned, full-bodied patches. Tube-modeled filters, four envelopes, assignable modulation, and a tempo-synced LFO help shape movement and tone, while Age controls introduce drift and dusty character. Start with over 350 patches by Richard Devine and Mark Ovenden, or explore Smart Sound Randomization while keeping selected modules locked. Eight macro controls offer quick adjustments, making Vacuum Pro approachable for preset-focused hobbyists while retaining depth for hands-on sound designers.
