Bassline is presented under the strapline Vacuum evolved, and its design is stated directly: the AIR Bassline emulates the sound of classic mono synths with a contemporary twist. The Bassline is a monophonic vintage synthesizer featuring Vacuum Tube Synthesis with an evolved version of AIR's vacuum tube circuit modelling made first famous by AIR Vacuum. Vacuum is considered by many the reference synth for Avid's Pro Tools. Perfectly capture the crunchy, warm sound of the analogue era, with the next generation providing incredible features without compromising that superb — the sentence trailing off, but the intent is clear. That lineage matters for the catalogue: the Vacuum engine's vacuum-tube modelling is the specific technology behind the instrument's distortion character, and AIR's own description of the base Vacuum product notes that for a synth plug-in it sounds surprisingly unlike a synth plug-in, exhibiting a real, dirty, and analog quality. Its effects are documented: Bassline also comes packaged with four integrated AIR effects (Chorus, Delay, Compressor, and Hype), as well as two built-in distortion algorithms (Overdrive and Clip). Its global controls are documented with specific values: bend range — number of semitones up or down controlled by MIDI pitch bend messages, 0–12; glide time — amount of time to slide from the pitch of one note to the next played, 10.0 ms to 2.00 s; and level, −Inf dB to +6.0 dB — the glide time range being the practical detail a bass producer cares about, since the length of a note-to-note slide is a defining characteristic of bassline playing in electronic music. It is listed at $99 through European distributors and is described as a monophonic vintage synthesizer. A Version 1.2.0.10 update for Mac is provided, and AIR Music Technology products require registration with the manufacturer at airmusictech.com and with my.plugivery.com/redeem to activate your licence. It runs in VST, VST3, AU, and AAX formats on Windows 10 and 11 or macOS 13 to 15, with full support for MPC standalone and desktop systems. It suits electronic music, house, techno, hip hop, and film score production, and the monophonic restriction is the design decision that matters — one voice, full attention to the signal path, and the glide and legato behaviour that polyphonic instruments handle less naturally. #Bassline #AIRMusicTechnology #Vacuum #VacuumTube #MonoSynth #BassSynth #AnalogModeling #TubeSynthesis #Overdrive #Clip #Chorus #Delay #Compressor #Hype #Glide #Portamento #BendRange #House #Techno #HipHop #ElectronicMusic #MusicProduction #VST #VST3 #AU #AAX #MPC #Standalone #FLStudio #AbletonLive #LogicPro #Cubase
