PsiLoops is a live loop app that lets you play a full bass-music set from your iPhone or iPad. Drop the drums, stack melody loops, fire a riser into the drop and ride the filter. Every change waits for the next bar, so it always lands in time, even if you've never made music before. Everything is on one screen, laid out like a groovebox, so your thumbs know where to go. PLAY A SET • Drum kits you build up layer by layer, from a lone kick to the full beat • Four rows of melody loops in two banks, each with its own volume, and every pad shows its loop's waveform • Rise and Drop sweeps for transitions, plus a grid of one-shot hits • Six effect knobs, always in reach: Filter, Reverb, Echo, Gate, Flanger and Mushroom • The Dice deals new sets when you're out of ideas ALWAYS ON THE BEAT • Quantize: loops, sweeps and drum changes land on the next beat, bar or two bars • Tempo anywhere from 50 to 200 BPM: hip-hop, dubstep, drum & bass and everything between • Learn mode labels every control. Live mode hides them and gives you bigger pads. SOUNDS FROM REAL ARTISTS Packs from 17 bass-music producers, from London to São Paulo: drum & bass, dubstep, riddim, psytrance, techno and hip-hop. RECORD AND SHARE Rec captures your whole set, plus your mic if you switch it on. Rap or sing over the beat, then share it from the app. SEE THE MUSIC MOVE Five visualizers: Phrase, Spectrum, Levels, RGB Wave and Spores. Tap any of them to go full screen. LOOP LAB: MAKE YOUR OWN SOUNDS (Pro) • Step Sequencer with 20 synths and samplers, keys and scales, layers, an arpeggiator and patterns up to 8 bars • Drum Lab: program beats up to 8 bars long across 14 lanes from 196 drum sounds, or import your own • Turn any MIDI file into loops: see every track, drag over the bars you want, hear them, and save as many to My MIDI as you like • Cut Loops: bring in any audio and it finds the tempo and snaps the loop to the bar • My Loops: every loop you've made in one place, ready to share as a tempo-tagged WAV or as MIDI • Set Builder: put your own loops into a set and play it live next to the artist packs ADVANCED EXPORT (Pro) • Stems: drums, both loop banks, one-shots and mic as separate files, ready for any DAW • MIDI: your whole performance, a track per part • WAV, FLAC or AAC, with streaming or club loudness PSILOOPS BRIDGE: PLAY INTO YOUR DAW (Pro) Our free Mac plugin (VST3 and Audio Unit, from psiloops.com/bridge) puts PsiLoops on a track in Ableton Live and other DAWs, over a USB cable or Wi-Fi. • Follows your DAW's tempo and starts on its bar • Drums, both loop banks, one-shots and FX on their own tracks, plus the notes as MIDI • Capture the last 4, 8 or 16 bars as WAVs and MIDI PLUGINS (for Pro subscribers) Instruments ported from our desktop plugins, bought once and kept. They play in the Step Sequencer, so they layer with everything else. • Growl: dubstep, riddim and tearout growl bass from one voice, with 24 presets and its own 16-step movement sequencer FREE OR PRO The free app is a whole instrument, not a demo. You get every control, all six effects, the Dice, the visualizers, a starter library of kits, loop sets and one-shots, and recordings up to 3 minutes long. PsiLoops Pro is a monthly subscription ($3.99 USD a month). It unlocks every artist pack (plus new ones as they land), unlimited recording, Loop Lab, Set Builder, Advanced Export and PsiLoops Bridge.

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.
