SpringSound is a physical-modeling audio synthesizer that produces sounds by simulating interactions and vibrations of a set of activators and masses connected to springs. The model offers detailed control of an array of features including: gravity, bouncing, fluid and static friction, mechanical limits, non-linear functions, and more. SpringSound is provided with a very large set of sound presets that you can tweak and save. Small video introductions are available: http://www.youtube.com/watch?v=L1GF7HkSV9c and https://www.youtube.com/watch?v=gdYuZ07nmRo And an audio demo of some presets: https://soundcloud.com/christophe-duquesne/demopresetspringsound It can be used as a sound generator or as an effect using its Audio-In feature, opening a new world of physical modeled effects. It is fully Audiobus® 2 and inter-app audio compatible, and manage state saving. SpringSound can be controlled by a standard MIDI keyboard and directly from the iOS device screen. It is complete with the new MIDI MPE (expressive MIDI) and therefore can be controlled by most expressive controllers like the Haken Continuum, ROLI Seaboard, Linnstrument, Madrona Labs Soundplane, etc. SpringSound app is designed for optimum use with the Haken Continuum (www.hakenaudio.com) and integrate an IOS Continuum Remote (iPad only) allowing a very comprehensive and accurate remote control of the Continuum from your iPad (access to all parameters except programming the Eagan Matrix). SpringSound has be designed to explore sounds domains you won’t be able to access with other synthesis technics. It expands your sonic palette with a new world of physical sounds. It is a rich musical instrument, a sophisticated sound-design tool and an entertaining sonic playground. SpringSound is the big brother of my former Ackorage-Spring app.

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.
