ROTOR is the new app that turns your device into a complete music performance suite. Using the optional ROTOR controllers, which can be purchased separately, it also brings the reactable tangible music experience that has captivated musicians such as Björk, Coldplay or Gui Boratto, for the first time into the iPad. **PLEASE NOTE: This App is officially supported on the following devices: iPhone 4S and newer, iPad Air/Air2, iPad Mini 2/3/4, and iPad Pro.** NOT A CONVENTIONAL SYNTHESIZER, NEITHER A SEQUENCER OR DAW… … although it includes components from all of them. ROTOR incorporates dozens of modules, among instruments, audio effects, modulators and controllers, all interconnectable between them, which can be used for creating the most expressive and intricate patches in a unique way. It is an unprecedented multitouch/tangible instrument specially designed for live interaction and performance. TANGIBLE CONTROL With our exclusive physical control objects especially conceived for the iPad, and which can be purchased separately, ROTOR brings the unique tangible experience of the reactable for the first time to the iPad! This means that while all standard multi-touch capabilities are preserved, the ability to control any parameter by moving and twisting our tangible pucks over the iPad’s surface, brings 3 additional degrees of freedom to each hand! The controllers are available in our website, but this app can also be perfectly used without them. ALWAYS IN SYNC AND IN KEY ROTOR comes with automatic real-time key detection and time stretching algorithms that allow for samples, loops and sequences to stay not only in sync but also in harmony with each other. All wavefiles can be configured either as masters, thus determining at any instant the tonality of the whole session, or as slaves, thus adapting automatically to this computed tonality. WORKFLOW INTEGRATION AND COLLABORATION ROTOR MIC/LINE IN module and its panoply of effects and modulators allows to process voice, guitars, or any other instrument, in unheard ways. With Audiobus, ROTOR can be used as an input/output device in combination with any other compatible music apps. Any ROTOR module can also receive external MIDI control from any user-selectable MIDI port/channel. Moreover, its integration of Ableton Link allows ROTOR to play in perfect sync with Ableton Live and other Ableton Link compatible iOS apps running in other devices. FROM COMPLETE CONTROL TO INSPIRING SERENDIPITY ROTOR includes dozens of multi-touch control panels such as virtual keyboards, polyphonic and monophonic step-sequencers, envelope generators, or 2D panels, which empower to control in real-time, every detail or nuance of the performance. On the other hand, interconnecting less linear and less predictable modules, such as the accelerometer input, the beat slicer or the feedback delay, opens a whole universe of generative and serendipitous creations. This, combined with ROTOR’s live recording capabilities, which simplifies the capturing of loops on-the-fly and always in sync, turns ROTOR into the ULTIMATE LOOP CREATOR MACHINE. SONIC VERSATILITY ROTOR also comes with 100+ high quality loops and sessions created by professional music producers. Along with these loops, users can import their own ones and combine them with ROTOR’s advanced synthesis and processing capabilities. From House or EDM to the most experimental generative soundscapes, ROTOR sonic versatility is unparalleled.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
