WARBL and WARBL2 are plug-and-play USB (and BTLE) MIDI wind controllers that allows the traditional musician to practice with headphones using familiar playing techniques. Designed to simulate a variety of open-tonehole wind instruments such as tin whistles, flutes, and bagpipes, WARBL has optical sensors and real toneholes for continuous finger sensing and realistic feel. An air-pressure sensor allows playing with breath or a bagpipe bag. WARBL does not produce any sound on its own. It is designed to control hardware MIDI sound modules or MIDI sound module apps running on an iOS device, for example AppCordions "Celtic Sounds" or Roland Sound Canvas. The WARBL Configuration Tool allows complete control over the air pressure sensitivity, vibrato/pitch bend, expression, and many other settings. You may adjust and save settings to design the instrument of your choice. The WARBL supports saving three preset instrument configurations, for example, Whistle, Uilleann Pipes, and Great Highland Bagpipes. The buttons on the back of the WARBL may be programmed to switch between the instrument preset configurations, change the octave, send MIDI messages, and many other options. To use, just plug in your WARBL to an Apple USB Camera Adapter connected to the Lightning port on your device, run the app, touch "Connect WARBL" at the top of the control panel and begin configuring your WARBL. Or if you have a WARBL2 with BTLE, press the BT MIDI button on the navigation bar to manage the connection to your WARBL wirelessly. When connected, the status at the top of the page will show "WARBL Connected" and you'll see MIDI event information on the display. Touch the yellow “info” buttons for instructions on using each section of the Configuration Tool.

SWAM Cello for iOS: Unmatched Realism and Expressive Power in Your Hands Experience the cutting-edge Physical Modeling technology of SWAM Cello 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 cellist. 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 Cello, 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 Cello 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 Cello 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 cello 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 Cello 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 Cello unlocks the full range of expression. Music Producers: Need a mobile setup to produce music from anywhere without carrying around expensive gear? SWAM Cello 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 Cello, 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 cellist, SWAM Cello needs expressive input for maximum realism. With SWAM Cello 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.
