Read full description

Fusion is an interactive and expressive multimedia MIDI and OSC controller. Our simple, yet powerful, interface allows users to experiment with built-in graphics while also providing MIDI / OSC control using real-time sensor data such as 3D motions, audio (microphone) and heart rate/digital crown (Apple Watch). CONNECTIVITY: Connect to MIDI compatible software and hardware via Bluetooth MIDI, USB or WiFi. Connect to OSC compatible software using the local network/IP Address (e.g. WiFi). Note: Our app asks for permission to use Bluetooth to send Bluetooth MIDI from the phone to compatible hardware. Display the in-app graphics on an external monitor using an HDMI connector/dongle. SUPPORT & COMMUNITY: Comprehensive support for Fusion can be found on our website at floverse.ca/support. Users can also connect with other artists in our FloVerse Discord community via the in-App link. Our website also offers pre-built Ableton templates and how-to guides. COMPATIBILITY: While highly compatible with iPhones and other devices, lag in MIDI output from the Apple Watch can occasionally occur. Enjoy effortless MIDI / OSC generation with our app and explore limitless creative possibilities. Minimum recommended is iOS 16.0 or above and Apple Watch OS 8.0 or greater. Known compatible DAW software for Mac: Ableton Live, Logic Pro X, FL Studio, Reason, Cubase, Reaper, Studio One and more. Known compatible software for iPad: FL Studio Mobile, Synth One, Nanostudio 2 and more. Fusion also works with non-musical software (e.g. TouchDesigner, Resolume and Isadora) that support control via MIDI or OSC. DATA USE & ACCESS: Healthkit permission is requested because it is required to access Apple Watch data such as the heart rate.

Relic Flow is a generator of Lo-Fi rhythms, noise patterns and drum loops based on unique synthesis algorithms from NightRadio. More than 4 billion samples from the depths of the Mathematical Universe! Features: * search for new sounds with three buttons: next random set, edit code, previous set; each set of 12 sounds corresponds to a code of 8 characters; * three types of keyboards for live performing: on-screen buttons, PC keyboard, MIDI input; * several processing parameters + control via MIDI; * real-time audio recording to WAV (32-bit); * export to: WAV (one file or a set), SunVox (samples + effects in one file), text clipboard; * the LCK button freezes individual samples - they will not change during the search for new sets; * iOS Audio Unit Extension (AUv3). Double clicking on a parameter opens a window for setting the exact value. If you enable the Hold option, the notes will play endlessly, without reacting to key release (noteOff) events; turning the note on again works like turning it off; there are two ways to enable this option: 1) using the Hold parameter in the "MIDI Mapping" window; 2) by pressing the HOLD button, which appears in place of LCK while playing the musical keyboard: press HOLD, release the desired notes - then the released notes will continue to play.
