Whether you’re a composer, producer, or live performer, this revolutionary app delivers unmatched realism, efficiency, and flexibility in a lightweight and intuitive package. Unlike traditional sample libraries, SWAM Violin Section doesn’t rely on pre-recorded articulations. Instead, it generates the sound in real time, reacting dynamically to your playing style, whether you're working in classical, cinematic, jazz, or modern electronic music. Why Choose SWAM Violin Section for iOS? Unparalleled Realism – Each violin section is fully controllable in terms of expression, vibrato, bow pressure, bow position, tremolo, and more. No need to switch between different articulations—just play and shape the sound in real time. Enhanced Efficiency – No more endless searching for the right articulation or sample. With SWAM Violin Section, you have immediate access to every possible playing technique at your fingertips. Faster Workflow – Control velocity, expression, and phrasing seamlessly while switching effortlessly between staccato, legato, spiccato, or pizzicato just by playing. Smart Room Simulator “Ambiente” – The built-in room simulator ensures that all violin sections in your mix interact naturally, allowing for a centralized UI to position every section in a shared acoustic space without tweaking each plugin separately. Top Features at a Glance Individual Section Control – Adjust the expressivity of each violin section independently, fine-tuning vibrato, bowing techniques, dynamics, and more. Standalone & AUv3 Plugin – Use SWAM Violin Section as a standalone app for real-time performances or integrate it as an AUv3 plugin in your favorite DAW. Customizable Sound & Playability – Personalize the tone, resonance, and bowing articulation to match any genre or style. MIDI & MPE Compatibility – Play expressively with MIDI controllers, MPE devices, wind controllers, or even directly from your iOS device’s touchscreen. Seamless Integration with DAWs – Perfect for mobile music production, SWAM Violin Section works effortlessly in Logic Pro for iPad, Cubasis, AUM, GarageBand, Camelot Pro and more. Lightweight & Powerful – Thanks to state-of-the-art Physical Modeling technology, you get a realistic and highly responsive string section without the need for massive sample libraries. Who is SWAM Violin Section for iOS Designed For? Film & Game Composers – Achieve lifelike, expressive violin section performances directly from your iPad or iPhone. Music Producers – Use real-time expressivity to shape your sound instantly, without limitations. Live Performers – Integrate SWAM Violin Section into your live setup for dynamic, high-quality string section performances on the go. Orchestrators & Arrangers – Create and refine rich, full orchestral arrangements with deep control over every section’s expressivity. Important Notes For the best experience, we recommend using a device with an Apple Silicon chip (M1, M2, M3, or later) for optimal responsiveness and real-time performance. Like the solo SWAM Strings instruments, SWAM Violin Section is monophonic, as it accurately replicates real bowed string instruments, allowing only double stops where realistic fingerings permit. To fully explore the expressive power of SWAM Violin Section, a MIDI controller capable of continuous expression (such as an MPE device, breath controller, or expression pedal) is recommended. Take your string section to the next level with SWAM Violin Section for iOS and redefine the way you create, perform, and produce music—anytime, anywhere!

QuadroSphere is a great tool for bringing an instrument to life by creating a soundscape with a constantly moving sound source. QuadroSphere splits the incoming audio signal into 4 distinct coloured frequency bands using the frequency bar. Each band has an associated coloured sphere allowing you to control the pan, stereo separation and volume level. You can use this plugin as a way to impose subtle control over stereo placement with little or no movement, or go crazy with random automation. Adding effects such as reverb or delay on a specific frequency band can help create a lush atmospheric swirling which surrounds the listener. This is great for musicians trying to create minimalistic ambient or tranquil soundscapes. You can create up to 12 snapshots of the sphere parameters and effect settings, then morph between them at a designated speed (measured in beats). You can also enable continuous randomization mode, and have full control over which spheres and control which parts are automated. You can also use QuadroSphere as a stereo splitter, using the additional outputs to add your own effects to band outputs. Key Features: ○ 4 Configurable frequency bands. ○ Control stereo separation, level and pan for each band. ○ Create up to 12 Snapshots. ○ Morph between various panning, width and frequency band levels. ○ Modulation control for automated sweeps around pan center. ○ Convert MONO signals into a pseudo-stereo image. ○ Per band Haas, Delay, Reverb, Chorus and Compressor. ○ Allows combined and individual per-band audio outputs. ○ Continuous randomized morphing of the stereo field. ○ Built in Preset Manager with drag and drop support. ○ Power and Solo for each band. ○ Controlable morph speeds. ○ Various animated transition modes. ○ Access most options using AU parameters or MIDI CC control.
