VOSIS is a synthesizer combining audification of greyscale pixel data with several image filters. It is a tool for image sonification, visual music composition, and experimental sound design. The audification of pixel luminance values creates shape-timbre relationships. Pixel scan rate is controlled in terms of note interval, octave, and scale to give varying pitch between image regions. The ADSR envelope allows one to play images as a non-linear sequence of pitches with varying wavetable/timbre. For more features including presets and unlimited recording see VOSIS Pro.

Musicians have used audio samplers for decades, triggering drum sounds, pianos, and hundreds of other instruments using MIDI keyboards and sequencers. SmashCut brings the same sort of functionality to video content. Load in any video from your camera roll, easily set cue points in the video, and you're ready to play with video in a new way. The app responds to MIDI note messages to seek to cue points, and start or stop playback. With MIDI CC messages, you can scale, rotate, and transform the video in a live and interactive way. And if you don't have a MIDI keyboard, you can still use all of the features of the app -- there's a built-in MIDI controller that you can use on a second iOS device. What can you do with SmashCut? If you're making a presentation using video, you can trigger play and stop using the remote, and move to different cue points easily. If you stream video or podcast, you can use SmashCut to cue to a video clip with no hassle or headache. The iPad version of the app runs on a Silicon Mac, and works well with streaming software such as OBS. If you have a band, and are putting on a show, you can sequence video to keep in time with the music. SmashCut is a great way to put together a music video, or to just cut, splice, and glitch video for fun. Instead of trimming video clips in a conventional editor, you can play with video like you would a musical instrument. There's full support of MIDI, and also an easy Wi-Fi based connection system; if you have two devices on the same Wi-Fi network, they'll connect in seconds. You can use the iOS built in screen recorder to capture video and audio from the app. The app is universal, running on iPad, iPhone, and Silicon Macs. There's a watermark on-screen that can be removed with an in-app purchase.
