Duplex Browser


Duplex is a collection of scripts that control various aspects of Renoise with plug-and-play support for a wide range of hardware. The applications range from controlling basic aspects of the Renoise application (like Mixer, DSP chains, Pattern Matrix), to more adventurous applications like sequencers and performance tools.

What makes Duplex special is the strong focus on bi-directional communication. In practice, this will ensure that your controller is always in sync with Renoise, no matter what you do.

Note: Duplex is an optional add-on, you can use any MIDI/OSC capable controller with Renoise without having to go through Duplex.

As a script author, using the Duplex framework can assist in creating programs that are adaptable for a wide range of hardware. It greatly simplifies tasks like creating sliders from buttons, or setting the LED lights on your controller using standard RGB values, and in addition it will automatically perform background tasks such as optimizing outgoing communication (to make controllers more responsive), etc.

Duplex is a standard Renoise tool (xrnx), can be downloaded from tools.renoise.com, and installed by dragging the file onto the Renoise application. Since Duplex is written entirely using the Renoise API, anyone can extend and modify it. The official version, however, is maintained by the Renoise team.

Basic usage

When installed, a new menu will appear, containing a large number of presets with names like "Launchpad Mixer + Matrix", or "Simple TouchOSC template". Each of these configurations represent a mix of different programs that we have found to be useful. Select one of them, and the Duplex Browser dialog will appear. From here, you can turn that configuration on/off, and switch between devices & configurations. This window also contain a unique feature in Duplex, a 'virtual' representation of the hardware using native Renoise UI components.

For the most part, the Duplex front-end is self-documenting - mouse over any part of the interface to get help and additional information about what each buttons/control does. Also, download the manual (english, japanese) to have some of the most common questions answered
- For information on how to write your own applications, look here (Renoise community) or dive in to the Duplex framework documention here
- If you own a non-supported controller, your can read this introduction on how to write a control-map.
- Remember that you are never on your own - post any questions you might have in the scripting forum.
