Roostbox
Read full descriptionHide full description
Roostbox is a groovebox that looks like a retro arcade cabinet and plays like one. It makes techno and other electronic music live, by hand: fly a ship through a beat, ride the faders, flick the stick, and every gesture you make is recorded and loops with the beat. It is a different way to play electronic music live. There is no step grid to program and no timeline to edit. Everything on screen is a control, you play it with two thumbs, and the loop keeps what you played. Two kits are in the box, and everything is free: both kits, the whole performance surface and the AUv3 plugin. No purchase, no account, no ads. Play it standalone on iPhone or iPad, or load it as an instrument inside AUM, Loopy Pro, Cubasis, Drambo or Logic Pro for iPad. TWO KITS IN THE BOX SPACE: fly a ship through a beat. Where the ship goes picks the groove: four-on-the-floor, backbeat, offbeat, broken, sixteenths. The cockpit page holds the mixer, a stick for filter and grit, overdrive, pump, tape, delay, reverb, crush and a DJ filter. A 303-style acid bass and a drum synth make the sound. PLIVKA: a four-track techno box. Kick, bass, snare and hat, each with a pattern control and a hit control, laid out over five pages: Rhythm, Sound, Perform, FX and Mix. The bass line is a Turing machine that mutates as much or as little as you let it. UNDER THE HOOD - Euclidean rhythm generators, a Turing machine sequencer and a trigger sequencer drive the patterns. - A drum synth and a 303-style acid bass synth make the sound. No samples. - Every fader move is recorded as motion and loops with the beat. Undo and redo if you change your mind. - Scenes: snapshot the whole kit and switch on the next sixteenth, beat, bar or pattern. - Master effects: delay and reverb sends, filter, crush, tape, compressor, sidechain pump and a limiter. - MIDI learn: map any control to a hardware controller. - Landscape only. Made for two thumbs. AUv3 The plugin is the same instrument as the app, with the same two kits, and it is free. It follows the host tempo and transport. Jam in the standalone app; record into your DAW with the plugin. WHAT 1.0 IS Two kits, built to be played. Building your own kits is not part of this version. Roostbox is made by one person.

UN/T
Read full descriptionHide full description
UN/T-01 is a drum machine with two engines. It has six tracks: BD, SD, HH, PERC, TOM and CY. Every track is either a synthesized 808 voice or a sample player, and you switch each track on its own. Run a synth kick next to a sampled snare. TWO ENGINES The 808 voices are synthesized the way the original circuits work, with Tune and Decay on almost every voice and longer decays than the hardware could do. In SAMPLE mode a track plays one of the factory sounds or a file of your own. SAMPLES Four factory sample sets, Slam, Cushion, Grime and Session, plus 808 samples of every voice. Load your own WAV, AIFF or FLAC files on any track. Two sample modes: VARI changes pitch and length together like a tape sampler, STRETCH changes pitch and length separately. SEQUENCER 16 steps, or 32 over two pages, with velocity and decay on every step. Every track has its own length from 1 to 32 steps, so patterns can drift against each other. Swing, step speed, Euclid with hits, length and rotate, copy and paste, and randomize and mutate for quick ideas. PRESETS 48 factory presets. Init is the plain 808 kit. The other 47 are genre kits, from electro and Miami bass to boom bap, trap, house, techno, UK garage, amapiano and drum and bass. Save your own. MASTER FX Shared distortion and reverb with a send on every track, a lowpass filter, a compressor, master volume and an always-on limiter. USE IT YOUR WAY UN/T-01 runs as a standalone app and as an AUv3 plugin in your iOS host. Each track has mute, solo and choke. Multi out sends every track to its own output in a host that supports it. Free. No ads, no tracking, no account.
