Adaptive Use Musical Instruments (AUMI) software interface enables people who have very limited controlled (voluntary) movement to independently engage in music making. The Adaptive Use Musical Instruments software interface enables the user to play sounds and musical phrases through movement and gestures. This is an entry to improvisation rather than “hitting the right notes” or playing set pieces of music. Instead, the software uses music as a way for participants to express a range of affects, both by themselves and in response to, or in conversation with, others. While the AUMI interface can be used by anyone, the focus has been on working with people who have profound physical disabilities. In taking these participants as its starting point, the project attempts to make musical improvisation and collaboration accessible to the widest possible range of individuals. This approach also opens up the possibility of learning more about the relations between ability, the body, creativity and improvisation, from within a cultural context that does not always acknowledge or accept people with disabilities. This iOS version of AUMI runs on devices with cameras, and can run on iPhones, iPod touches, and iPads. A large assortment of sounds can be triggered with configurable amounts of sensitivity. AUMI also can be used as a MIDI controller to access other iOS based synthesizers or external equipment (using the iPad's Camera Connection kit or via Core MIDI over WiFi.) AUMI can also import audio from other iOS or desktop apps to be used as melodic or percussive instruments. AUMI can capture a record of the movement in the session, which can be exported and turned into reports in a clinical setting.

About

Sacred Geometry Visualizer

Features
Read full description

Ten sacred geometry patterns, drawn live, moving with whatever you play. Flower of Life. Metatron's Cube. Sri Yantra. The Merkaba. The Torus. The Golden Spiral. The Thirteen-Petaled Lotus. The Triple Spiral. Celestial Mandala. Cosmic Bloom. These are forms people have been drawing for thousands of years, and they hold attention in a way an ordinary screensaver does not. Here they are rendered frame by frame in real time and tied to sound. The audio is split into six frequency bands with beat detection on top, so the structure responds to the shape of a track instead of just pulsing along with it. Nothing is pre-rendered or looped, so the same song never looks quite the same twice. Sit with one while you meditate, leave it running through a long record, or send it to the TV over AirPlay and let the room watch. Two Ways to Drive It: Play your own music. Bring in tracks from Files or iCloud Drive, or pull songs and whole playlists from your Apple Music library. Or open the microphone. Point it at a singing bowl, an instrument, a room full of people, and the geometry follows the sound around you. A Real Music Player Underneath: This started as a visualizer and became a player worth using on its own. Ten-band EQ with presets and a preamp Gapless playback, and crossfade up to twelve seconds Volume leveling, so a quiet track does not vanish between two loud ones Playback speed from half to double, pitch corrected Background playback with lock screen, Control Center, AirPods, and CarPlay controls Playlists, and browsing by artist, album, or genre Favorites, play counts, Most Played, and Recently Played Up Next queue, shuffle, repeat, search, and sorting Sleep timer with a soft fade, and an A-B loop Embedded lyrics and album art Picks up exactly where you left off Record It: Capture the visualizer as video and save it to Photos or send it wherever you like. In microphone mode the recording can include the audio in the room. Make It Yours: Swipe to change patterns, press and hold for the full carousel, tap to hide the controls. Each of the six frequency bands has its own sensitivity, so you can decide how much the bass moves things versus the high end. Every pattern remembers its own settings, and you can save presets and come back to them. Privacy: No ads. No accounts. No analytics, no tracking, no third-party SDKs. Your library, your settings, and your recordings stay on your device. Microphone audio is analyzed on the phone and never uploaded. Free, with nothing locked behind a purchase.
