Parat+ is an Open Sound Control (OSC) and MIDI app for musicians and artists working with audio and visuals wishing to control different software and hardware devices. Controller, interface, instrument, Parat+ offers spontaneous and sophisticated multitouch gestural control to perform and interact in the most precise, yet efficient and intuitive ways. Parat+ will empower those musicians and artists seeking to extend their flexibility with technology and explore interactive controls.

Developed by practitioners for practitioners, Parat+ is a tool for the musician, artist and everyone else who use technology to advance their art.

Much more than a virtual ‘fader box’ to control your parameters in realtime, it allows you to record, remap and program controls instantly and intuitively. Swipe and multitouch gestures record, loop and remap the interval of each fader and responsivity curve. Rescale, enlarge, pause and interrupt to modify your controls in realtime. Control sound levels, effects parameters, synthesis, lights and more via OSC and MIDI simultaneously.

Parat+ combines powerful software and hardware parameter control with data automation and manipulation. It is fully compatible with OSC enabled software such as:
• Max
• PD
• Processing
• Digital Performer
• Reaper
• Reaktor
• Renoise
• Ardour and more.

All other software and hardware including DMX for lighting rigs can be controlled via MIDI.

The fader-style controller modules at the core of Parat+ can control parameters and functions of any MIDI and/or OSC enabled software and hardware. Multiple OSC targets can be defined to optimise user flexibility.

The Faders offer unparalleled realtime control via the multitouch three point control feature which allows the user to remap the interval and responsivity curve of each fader in realtime.

The touch gesture features include:
• One finger gestures to control the fader value.
• Two finger gestures to adjust the fader's minimum and maximum values.
• Three finger gestures to adjust the minimum, maximum and responsivity curve.

Use absolute touch mode to have the Fader value jump to whichever finger position is applied and relative touch mode to avoid any sudden jumps due to changes in finger position, allowing for seamless transitions in volume etc..

Each Fader can also be remotely controlled and automated by the Gesture Recorder, internal LFO generators, audio analysis and sensors, external OSC sources and MIDI controllers.

Use Parat+ as a central control hub for any performance and production setup, and shape OSC data streams sent to Parat+ to control your software and hardware parameters. Incoming OSC data (e.g. data from sensors, analysis modules and generative algorithms) can be modified and modulated using the the scaling and modulation features of Parat+ Sources and Faders.

Gesture recording and playback allows looped and one-shot automations of unlimited length.

The simplicity and coherence of the tools enable any novice to venture into custom built controls, while the accustomed performance system developer will appreciate the time saved for complex setups.

The philosophy behind Parat+ is to extend and assist your practice without imposing an approach. The app has been designed with the knowledge that creative work requires tools that can grow with their users, allowing individual and intuitive creative application while maintaining flexibility and diversity. Artists who are familiar with programming will appreciate the intuitive approach to data handling and parameter mapping. Users who lack experience with sophisticated technology will find themselves empowered to embrace cutting-edge interactive technology in the most intuitive and approachable manner. By keeping technical concerns to a minimum, the user is free to make artistic and aesthetic choices guided by their own creativity, avoiding the constraints of conventional software and controllers.

Any chance of you guys adding AUV3 support?

Parat+, the MIDI & OSC controller app I've been waiting for...

30 faders that are customizable on the fly! Faders can be easily scaled, inverted, and switched from absolute mode to relative mode on the fly via the very convenient and accessible options wheel at the bottom of each fader. Gestures/movements of the faders can very easily be recorded and played back in either loop or one-shot modes. Doesn't seem to be any limit to the duration of these recorded gestures either. I can say that I have been waiting for an app like this for a while.
And I've only just scratched the surface with this app thus far. As of now I've only used it as a MIDI controller, but this is also an OSC controller app with additional sources that can be used to modulate the faders.
Along with saving presets of your favorite setups, it appears as though gestures can be recorded and stored as well. Faders can be named and color-coded (8 colors currently available).
With Parat+ I was very quickly able to vastly extend the mod matrix of (a beloved iOS Synth w/ a limited mod matrix), by adding another 30 customizable/recordable modulations to this iOS Synth via MIDI CCs. And since each fader can record it's own scalable gesture, these go far beyond any synth's basic LFO wave shapes or envelopes.
The developer is also very accessible and responsive. No worries on issues with customer support for Parat+. This is a great app!
