With Propellerhead's Rack Extension platform, developers can move faster from initial idea to finished product than ever before. Regardless of whether your skills lie in hardcore DSP coding or in creating beautiful samples, the Rack Extension platform has all the tools you'll need to develop stunning instruments and effects and bring them to market with minimum effort and maximum support.
The recently updated developer toolkit adds features and tools for developers to create even more advanced and great-looking instruments and effects. With the Instrument Development Toolkit, it's easier than ever to build advanced instrument Rack Extensions, even without prior coding experience.
Rack Extensions are full citizens of the Reason Rack, cross-platform compatible, copy-protected, future-proof, and easy to sell direct to Reason users in the Propellerhead Shop. How to become a developer.
Reason 9.2 has been released to the public, which means developers are now free to ship Rack Extension products featuring sample loading and an array of UI features such as panels, array support in displays, modifier key-clicks in displays and context menus.
With these technologies deployed to a huge user base of Reason 9 owners, the scene is set for a new generation of great Rack Extension products.
Rack Extensions are cross platform, and will continue to work in the next version of Reason, and the next after that. You focus on building cool products, not maintain code. The Rack Extension platform will be kept up to date with current operating systems, removing the need for developers to update their products.
A Rack Extension lives inside the Reason Rack, like any other rack device. They are fully integrated in the Reason user experience and work seamlessly with the host application. Automation, undo, cables on the back and music hardware integration—it's all handled by Reason.
With the Rack Extension technology, we have taken care of the mundane household tasks, so that you can focus on what matters: your product idea. Leave it to us to take care of file handling, automation, undo, music hardware integration and more.
The SDK comes with a library of useful code for Rack Extension development, such as FFT, memory handling, undo, sandbox, routing and communication with the Rack Extension host.
Recon is used to test and debug your Rack Extension project. It's a test bench version of Reason that lets you load and run your prototype Rack Extensions.
With the LLVM compiler, you compile your C++ code to bitcode that is used to build the Rack Extension. It's the compiled bitcode that is uploaded along with your Rack Extension's other resources to Propellerhead's automated build system.
The Rack Extension Designer (RED) is where you lay out and preview your 3D graphical interface.
As an alternative to creating your own GUI objects in 3D, more than 100 interface parts such as knobs, buttons, faders and display objects are supplied in the Parts Library. Each object can be customized to adjust properties such as color, texture, and more.
If you're apt at building sample libraries but don't speak the language of DSP, the Instrument Development Toolkit is for you. The Rack Extension SDK comes complete with an advanced scriptable sample player with a powerful array of built-in effects and more to kick-start your development. It also helps to convert content created for existing sample-based products into a Rack Extension instrument.
Help is there when you need it. We are as eager as you to see your projects finished and will always be there to help you out.
There is nothing like learning from your peers. As a Rack Extension developer you’re granted access to the Rack Extension developer forum — a lively and active community of developers. Check out the collection of stickies full of helpful tips to get started.
Testing is of course essential to a quality product release. The developer section of the our web site gives you access to beta testing tools to help you distribute beta licenses to your testers.
The SDK comes with ten written tutorials with code and scripting examples that will help you along the process from initial design to finished product.
To dip your feet in the Rack Extension technology, we have supplied three straightforward example projects that will show how to create a simple instrument, a simple effect unit and a device with a custom display.
For help and assistance, we are always available to help you out. Our staff can help and guide you with issues related to development, administration or sales issues.
Aside from Rack Extensions, Propellerhead offer several de facto industry standard technologies for developers to use.
ReWire is system for streaming audio from one application to another. Pioneered in Propellerhead Software's ReBirth, it is now supported in every major DAW on the planet. The API, which is written in ANSI C, also has support for play positioning information, MIDI streaming and a toolkit for communication between the applications.
The REX file format allows for free manipulation of timing and feel within a sampled groove. A REX file contains the original audio of the loop, the slices you have applied in ReCycle, and any effects or processing you have added in ReCycle. REX files are also compressed, using a non-lossy compression technique to save some precious hard drive space. The REX format has been implanted in just about any DAW or software sampler out there.
Remote is a protocol for handling communication between control surfaces (MIDI keyboards, remote control devices, etc.) and software applications (e.g. Reason). It handles everything from delivering MIDI note data from a keyboard to the application to using knobs, faders and buttons on a control surface for tweaking synth parameters in the application, controlling transport, etc. Remote also supports two-way communication, in order to make use of motor faders, dynamic displays and LEDs.
NN-XT is the flagship sampler in the Reason Rack. A fully featured sampling instrument, it comes with everything needed to build rich and natural sounding sample patches. The NN-XT file format is open to third party developers to allow external applications to create NN-XT patches.
Formed in 1994, Propellerhead Software is a privately owned company based in Stockholm, Sweden. Renowned for its musician-centric approach, Propellerhead has created some of the world's most innovative music desktop software applications, mobile apps and technology standards. Musicians, producers and the media have praised Figure, Reason, ReCycle and ReBirth applications for being inspiring, great sounding and of impeccable quality. Technologies such as ReWire and the REX file format are de-facto industry standards, implemented in all major music software. Today, Propellerhead's products are used all over the world by hundreds of thousands of professionals and enthusiasts for all kinds of music making.
