"QuantiChord" is a MIDI effect that generates chords from incoming notes and quantizes the results to a pre-defined scale. It can be used as a standalone application or as an AUv3 MIDI effect plug-in. The chord is generated by adding up to 8 transposed notes to the original note played. Once the chord is generated, it is quantized to limit it to the selected output scale. The application supports full internal and external MIDI connections for input and output. An internal sound bank is included. The AUv3 MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in. The host must support the Audio Unit v3 (AUv3) MIDI effect format. Hosts supporting AUv3 MIDI effect on iOS: Logic Pro, Cubasis, Beatmaker, AUM, Audiobus, NanoStudio, Auria Pro, apeMatrix.

SWAM Viola Section for iOS: The Next-Level String Section Experience SWAM Viola Section for iOS brings the power of Physical Modeling technology to your mobile device, allowing you to create realistic, expressive, and fully customizable viola section performances on the go. 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 Viola 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 Viola Section for iOS? Unparalleled Realism – Each viola 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 Viola 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 viola 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 viola section independently, fine-tuning vibrato, bowing techniques, dynamics, and more. Standalone & AUv3 Plugin – Use SWAM Viola 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 Viola 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 Viola Section for iOS Designed For? Film & Game Composers – Achieve lifelike, expressive viola 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 Viola 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 Viola 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 Viola 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 Viola Section for iOS and redefine the way you create, perform, and produce music—anytime, anywhere.
