About

SECTOR

This app allows musicians to slice and sequence audio loops using a probability-based matrix and a classic step sequencer. It offers time-bending effects for unique sound manipulation and real-time performance tweaking, bridging the gap between controlled patterns and random sonic exploration.

Highlights
  • Probability-matrix sample slice sequencer
  • Classic pattern step-sequencer
  • Time-warping transfer functions
  • Real-time performance tweaking
  • Import custom loops
  • Inter-App Audio and Audiobus support
  • MIDI Clock sync

Proud winner of a 2015 Electronic Musician Editors’ Choice Award! Slice and sequence your loops with a matrix of markov-chain connections. Introduce order with the probability based coin-flipping pattern sequencer. Bend time with warp functions for glitches and modulations. Tweak and trigger in real time performance. Get anything between rigid control and random chaos. • Unique probability-matrix sample slice sequencer • Classic pattern step-sequencer for absolute control • Time-warping transfer functions for various effects • Includes high-quality loops by Richard Devine, Sonic Mayhem, Arovane, Alex Matheu and Sunsine Audio • Import custom loops from other apps, AudioShare, Pasteboard or using iTunes FileSharing • Stream audio to other apps via Inter-App Audio or Audiobus • Synchronize to Inter-App Audio hosts such as AUM, Auria or Garageband • MIDI Clock slave/master to sync with other apps or hardware • MIDI control for triggers, volume, start/stop, and loading projects • Supports Audiobus Remote triggers • Record and export the results as perfectly synchronized loops • Audiobus state saving "One of the most innovative and entertaining audio apps you’ll ever encounter" - David Biedny at MacLife.com "Engrossing, beautiful, wild and a fine addition to the iPad studio" - Computer Music Magazine "This is already, I think, a must-buy. Going to have fun playing with it. Enjoy!" - Peter Kirn at CreateDigitalMusic.com "It is utterly brilliant" - John Walden at MusicAppBlog.com

Features
Read full description

Moebius Lab is a multimorphic sound processor which contains a synth, a varispeed stereo sample player, 9 time domain effects, 6 spectral effects, 7 slots for external audio application, and nearly 200 LFOs that can modulate each parameter. You can move the effects along two chains, and get endless combinations of incredible sounds. ALL the App parameters can be modulated with dedicates LFO (one independent LFO for each parameter!). To get you started, you have more than 200 ready-mades presets. Each effect has an in-line help with an explanation of the parameters. The screen is divided into 3 horizontal areas: the top one contains the sound source (Sample player/External Input/Internal Synth), the middle one contains the Time Domain Effects Chain with four slots for external apps, the bottom one contains the Spectral Effects Chain. The two effect chains are connected in a sort of Moebius Ring: you can route the signal from the Time Domain Chain to the Spectral Chain and vice versa. You can even add up to 7 IAA effects and/or instruments, the number of possibilities is huge! *** LIST OF EFFECTS (NODES) *** - EXCITER The Exciter Node distorts the signal below (Saturation) or above (Excitation) a given frequency. - RINGER A ring modulator with distortion and feedback. - KLAMPER Clamps the signal with some special features. - SWARMER A “superchorus”, excellent to create super fat synth sounds (and more). It is composed by a chain of modulated delay lines. - FILTER The Filter node has two configurations: Dub: dual low-pass high-pass state variable filter with resonance and overlap factor. Morph: a triple low-pass/band-pass/high-pass state variable filter with resonance and continuous morphing between the filter types. - SPLITDEL A dual band delay with feedback. - REDUKTOR This node can be used to decimate and do other “bad things” to your signal. - SHIFTER A dual band frequency shifter. - REVERSO Plays the signal in reverse at regular rate. - BRICKWALL A spectral brickwall filter. - GRIP This node samples and holds spectral components of the incoming signal, based on their amplitude. - BLUR A (noisy) “spectral reverb”. The duration of the spectral components is prolonged (blurred). - DEGRADER A spectral decimator. - FLUTTER Flutter is a sort of animated brickwall. Two spectral sinusoidal LFOs define the frequency boundaries. The spectral components which are inside or outside (depending on the Spectral Balance) these boundaries are suppressed. - PLATEVERB As the name suggests this is a classic Plate Reverb. - DYNAMICS PROCESSOR You can change the output sound using a compressor and expander effect. This is used to either reduce or expand the dynamic range of an audio signal. THE SYNTH The internal synth contains two band limited oscillators, a complex oscillator, a ladder filter, an envelope generator and a sub-bass oscillator. Other Features: - Audiobus and Inter-App Audio support (sender and FX) - Built-In​ Stereo Sampler with varispeed - Control Manager LFO for Parameters - Midibus, Virtual Midi and Network: 14 bit NRPN controllers - File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy - Snapshots Presets Morphing Pad
