rrarrow is the experimental noise machine / modular audio effect for the iOS featuring extended feedback capabilities. Key features: - Simplicity. The interface is simplified for faster assembly and more flexible connectivity — you can assemble your effect very fast and control all the processing parameters with the audio signal! - Feedback capabilities. You can add feedbacks to the audio chain to get some chaotic noise sounds . - 20 blocks for audio processing: - Sine generator. Basic oscillator with sine waveform - Saw and square oscillators - Signal multiplier - Delay - Frequency shifter - Envelope follower - “Lorenz attractor” - Quantizer - Sample-and-hold - Reverb - Special Lowpass filter - Clipper - Nonlinear shaper (for self-oscillating circuit) - two special waveshaping modules with “fold” and “wrap” distortion blocks that work with audiofiles: - lookup table. Loads up to 10 seconds of audiofile to be used as nonlinear transfer function - Players with/without interpolation and speed control - "scrub" block for semi-random granular file playback - Built-in audio recorder. Share the audio file to other applications or AudioShare. - MIDI support! Assign MIDI controllers to all faders. Supports network midi and has a virtual MIDI in. - Audiobus support. Now you can stream live audio directly to other Audiobus-compatible apps! See http://audiob.us for more information. Works as input and filter. - Audiobus state saving support - Inter-App Audio support - Background audio support: enabled when connected to Audiobus and user switchable otherwise. The 'background audio" switch is located in app's "settings" page iPad2/iPhone4S or newer is recommended for complex presets this app is optimized for iPad and iPhone 5 To get started please watch the tutorial videos on the website and read the user guide inside the app

About

TC

This app acts as a versatile controller for music software and hardware, allowing users to create custom interfaces for sending MIDI and OSC messages. It translates touch gestures and device motion into musical commands without being a synthesizer itself.

Highlights
  • Customizable multi-touch controllers
  • Device motion control (gyroscope/accelerometer)
  • MIDI over Bluetooth (Mac)
  • OSC over Wi-Fi (Mac)
  • Inter-app control via CoreMIDI
  • Support for external MIDI interfaces
  • Virtual MIDI output
Read full description

TC-Data is a MIDI and OSC (Open Sound Control) controller that sends messages to other apps and hardware. The app has over 300 multi-touch and device motion controllers and triggers which can be assigned to any MIDI or OSC message output. TC-Data is not a synthesizer, but it is designed to control them, plus any other MIDI or OSC software. With TC-Data, you create your own interface to send the gestures and touch motions you choose. There are no sliders, knobs, or buttons. TC-Data directly connects your touch movements to the outputs you program. Create MIDI notes, CC, pitch bend, patch change, and aftertouch messages with totally unique multi-touch controllers. Or send values directly to your program of choice via OSC, where you can build your own project using TC-Data as the front-end. Features • MIDI over Bluetooth (Mac) • Inter-app control via CoreMIDI • OSC over Wi-Fi (Mac) • Support for external MIDI interfaces • MIDI input passthrough • Virtual MIDI output • Fully assignable touch controllers • Gyroscope and accelerometer motion control • 300+ controllers and triggers • 14-bit MIDI CC support TC-Data is based on TC-11, an all-in-one multi-touch synthesizer. TC-Data takes the multi-touch controllers from TC-11 and opens them up to any external software.
