Roostbox

Read 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.

See your stereo field. Vectorscope 2 shows the shape of a stereo signal as you hear it: how wide it is, where it leans and whether its channels work together or cancel each other out. Rebuilt from the ground up, it runs as an Audio Unit (AUv3) inside GarageBand, AUM, Logic Pro and any other host, and on its own with your device's microphone or an audio interface. TWO VIEWS OF THE SAME SOUND • X/Y: the classic Lissajous display. Mono sits on the vertical axis, wide material spreads across the diamond, and a signal out of phase turns sideways. • Polar: the half-disc view, with left, center and right laid out as you'd place them in a mix. • Short or long trail, automatic or fixed zoom, and four trace colors. METERS THAT TELL THE REST • Correlation, from +1 (mono-compatible) to −1 (out of phase), so you catch phase problems before they reach a mono speaker. • Balance, so you know where the energy sits between left and right. • Peak and RMS level meters with held peaks and clip indicators. Tap to reset. • A notice when the input is mono, so a single vertical line never looks like a broken meter. MADE FOR EVERY SCREEN Vectorscope 2 lays itself out for the space it's given: an iPhone upright or sideways, an iPad, iPhone Duo folded or open, and a plugin slot in a host, from GarageBand's compact strip to its expanded view. QUIET BY DEFAULT On its own, the app starts with its output muted, so the microphone never feeds back through the speaker next to it. As a plugin it passes your audio through untouched.
