SWAM Viola for iOS: Unmatched Realism and Expressive Power in Your Hands Experience the cutting-edge Physical Modeling technology of SWAM Viola for iOS, now featuring the revolutionary Room Simulator "Ambiente"! Unlike sampled libraries, this virtual instrument doesn’t play pre-recorded sounds but generates authentic string performances in real-time, responding dynamically to your every nuance, just like a real violist. These instruments are NOT sample libraries. Unlike sampling, which uses recordings to replicate the sound of an instrument, physical modeling doesn’t generate a sound as such but creates the conditions for the system to create it according to an external input (like someone playing on a keyboard). This means every note is unique, and the instrument responds dynamically to your playing style. With SWAM Viola, you can unleash your creativity across any musical style—from classical to modern, film scoring to microtonal music. Whether you're performing live or producing music on the go, SWAM Viola is your ultimate companion. New Features and Key Benefits: Room Simulator "Ambiente": Take advantage of advanced spatial control with the built-in Room Simulator "Ambiente," which allows you to position the instrument in a realistic acoustic space, interact dynamically with other SWAM instruments in the same virtual room, and create truly immersive performances. Additionally, the legacy Reverb, EQ, and Compressor effects are available for fine-tuning your sound. Standalone and AUv3 Plugin: Perform in real time or integrate SWAM Viola seamlessly into your mobile production workflow. Intuitive, Inclusive Interface: Designed for everyone, including blind and visually impaired users. Expressive Control: Play with unmatched expressivity using the exclusive virtual bowing surface, MPE controllers, keyboards, breath controllers, or other MIDI devices. Top Features at a Glance: Access a library of presets, create your own, or import presets from the desktop version. Customize every detail of your sound, including timbre, vibrato, and dynamics. Micro-tune the instrument with the Pitch Manager, supporting devices like MAQAM for advanced tuning systems. Add built-in effects like EQ, and Compressor. Play with different viola bodies to explore unique tonal variations. Use AUv3 to integrate with your mobile DAW (Logic, Cubasis, AUM) or apps like Camelot PRO for live performances. Who is SWAM Viola for iOS Designed For? Wind Controller Players: Looking for a mobile setup to perform live without needing a computer while still achieving an incredible sound. Keyboard Players: Frustrated by the limited expressive capabilities of normal sample-based plugins? SWAM Viola unlocks the full range of expression. Music Producers: Need a mobile setup to produce music from anywhere without carrying around expensive gear? SWAM Viola is the solution. Musicians Seeking Expressivity: Looking for a virtual instrument that allows you to express the full range of your musicality easily on your iPhone or iPad. IMPORTANT: To fully harness the expressive power of SWAM Viola, a controller capable of continuous expression (such as a breath controller, expression pedal, MPE device, or wind controller) is required. Just like a bow is essential for a real violist, SWAM Viola needs expressive input for maximum realism. With SWAM Viola for iOS, you have the freedom to create lifelike string performances on your iPhone or iPad. Redefine your music with unparalleled realism and expressive depth—anytime, anywhere.
