Addictive Keys: Modern Upright is documented with an unusually direct statement of purpose: sometimes a grand piano is just too, well... grand. Maybe you need something smaller and more intimate. In those cases, the Modern Upright is the perfect choice. That framing captures a real production distinction: an upright piano is a different instrument acoustically, not merely a smaller grand — its shorter strings and vertical soundboard give a tighter, more percussive attack with less sustain and a boxier, more compact low end, which is why uprights sit differently in a mix and often fit better under a vocal or in a dense arrangement. The feature that defines the instrument is documented in detail: Modern Upright features seven microphone perspectives ranging from close to far, floor to soundboard and mono to stereo. This gives you nearly limitless sound design options and lets you tailor the sound of the piano to the exact needs of your song, all within the Addictive Keys engine. The perspective list is specific and worth carrying, because a soundboard microphone on an upright captures the instrument's mechanical and body resonance in a way no other position can, and the mono option is genuinely useful in a mix where a stereo piano would occupy too much space. Its position in the range is clear: it is one of four Addictive Keys instruments — Studio Grand, Modern Upright, Mark One, and Electric Grand — and Addictive Keys: Complete Collection pairs all 4 pianos at $249 list, against individual purchase. Requirements are macOS 10.13 or later (64-bit) or Windows 10 and 11 (64-bit), with an internet connection during installation, formats VST, AU, AAX (64-bit) and a standalone application on Windows and macOS, and the product should run on any host supporting 64-bit VST, VST3, AU, or AAX plugins. XLN Audio actively tests on Ableton Live 10 or later, Apple Logic Pro 10 or later, Avid Pro Tools 11 or later, Cakewalk by Bandlab, FL Studio 20 or later, Reason Studios 9.5 or later, Reaper 5 or later, and Steinberg Cubase 10 or later. It suits singer-songwriter, indie, jazz, pop, and intimate film scoring, and the "modern" in the name distinguishes it from a vintage upright — the recorded instrument is a contemporary piano, so the tone is cleaner and more even than a well-worn period instrument. #AddictiveKeysModernUpright #ModernUpright #AddictiveKeys #XLNAudio #UprightPiano #Piano #MicrophonePerspectives #Soundboard #Mono #Stereo #CompleteCollection #StudioGrand #MarkOne #ElectricGrand #SingerSongwriter #Indie #Jazz #Pop #FilmScore #MusicProduction #VST #AU #AAX #Standalone #FLStudio #AbletonLive #LogicPro #Cubase #StudioOne
