Air Music Technology originally created Vacuum Classic as part of their Creative Collection of instrument plug-ins that were included as part of Avid™ Pro Tools™. As the popularity of Pro Tools grew, more and more musicians and producers relied on the incredible sonic firepower of this amazing Synth. Vacuum Classic continued to evolve and demand grew.

Vacuum Classic is now available on its own, available to anyone who demands instant creativity in AU/VST formats.

Vacuum Classic is a monophonic vintage synthesizer featuring Vacuum Tube Synthesis with vacuum tube circuit modeling that perfectly captures the crunchy, warm sound of the analog era. With analog oscillators, multiple filters and envelopes and built-in audio effects.

Vacuum lets you dive deep into subtractive synthesis to recreate those sought-after analog sounds from the 70s and 80s. Tweak the switches, knobs and dials to program anything from basses, leads, pads or unique sound effects. Vacuum gives you two Vacuum Tube Oscillators. A nice touch with the four available wave shapes is that rather than just picking one, Vacuum lets you 'morph' between them. The output of the oscillators goes through a mixer, where you can apply drive/distortion and ring modulation, before being passed through high- and lowpass filters.

Included are a wide range of pre-sets designed by highly-acclaimed sound designers Richard Devine and Mark Ovenden. Covering everything from Leads, Pads, Bass, Arpeggios, Percussive, and FX sounds this library provides instant inspiration for anyone to tweak to their contentment.

The filters provide a smooth sound, but each offers a saturation control if you prefer a more aggressive sound. A really nice touch can be found in the 'age' knobs, where you can set an amount of pitch drift to apply to the oscillators, or the quantity of dust that might make the synth sound old and noisy.

This is a crossgrade available for all registered users of Vacuum Classic used in the following products: Pro Tools, AIR Instrument Expansion Pack 3 Complete, AIR Instrument Expansion Pack 3 Select and MPC Software.

Vacuum also offers a number of modulation options, including two envelopes, which can be set to retrigger in the settings page. There's also an on-board arpeggiator. For a synth plugin, Vacuum sounds surprisingly unlike a synth plugin, exhibiting a real, dirty and analog quality. The slick vintage synth-styled interface pays homage to some of the best vintage tube synths of the past, powerful and easy to use.
