PIANOTEQ 9: THE ULTIMATE VIRTUAL INSTRUMENT Pianoteq is an award-winning virtual instrument that simulates a wide range of instruments including pianos, electric pianos, harpsichords, vibraphones, guitars, steel drums, and more, using advanced physical modeling. Unlike traditional virtual instruments that use recorded sounds, Pianoteq generates sounds in real-time by calculating the physics of how strings vibrate and how the soundboard radiates sound. Why Pianoteq Stands Out: - Natural Playability: Physical modeling captures many of the subtle interactions and dynamic nuances found in acoustic instruments, providing a responsive playing experience. - Compact Size: Without relying on large sample libraries, Pianoteq requires only a fraction of the storage space of many virtual instruments, making it ideal for iPhone and iPad. Trusted by the Best: Steinway, Kawai, Bösendorfer, Bechstein, Petrof, Steingraeber, Grotrian, Blüthner, and Hohner have all endorsed Pianoteq for its faithful sound reproduction. Getting Started: - Connect a MIDI device to your iPad/iPhone. - Launch Pianoteq. - Start playing! Pianoteq also works as a plugin in any Audio Unit host application, such as GarageBand, AUM, Cubasis, Camelot, and more. Note: All instruments run in demo mode (with some keys disabled) until you purchase a Pianoteq STAGE license (unlocks two instruments) or link to an existing Pianoteq user account with a valid license. Licenses purchased on the App Store are valid across other supported platforms (macOS, Windows, Linux). Already own Pianoteq 8? Upgrade to Pianoteq 9 at an attractive upgrade price and unlock a new level of realism and expression. Simply launch Pianoteq 9, click “Restore Purchases”, and follow the instructions. Here’s what’s new in Pianoteq 9: - Richer tone and enhanced spatial depth: all modern and historical grands have been thoroughly revoiced. - A beautiful new Italian Triple Harp joins the Harp pack. - Electric pianos (MKII, Reeds) have been updated. - Expressive new “Sombre” presets for cinematic playing. - A refined, more intuitive mixer panel. - Portrait orientation and windowed mode now supported. - A new instrument: the Syngular synthesiser. Experience your instruments like never before, more vivid, expressive, and alive.
