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.
