Air Music Technology's Vaccum Classic is described as a classic mono synth - obviously in software form. Its added USP being that not only do you get a fully featured four oscillator subtractive mono synth engine but there's some extra tube circuit modeling in there to give more warmth and burn to the sound.
Whats more, its usual price of £99.95 has been discounted to just £1 - offer ends August 1st.
