RNBO 1.4.0 Released

We are excited to announce the release of RNBO 1.4.0. This release focuses on the RNBO Runner and Web Interface, longer term bug fixes, a handful of new objects, and improvements to existing features.

You can download the update now via the Max Package Manager. The latest Max 9.0.7 release is recommended for use with RNBO 1.4.0.

Here is an overview of some of the work in this release, as well as a comprehensive changelog including all new features and bug fixes.

RNBO 1.4.0 Feature Overview

RNBO Runner / Web Interface

• Stream recording: record multichannel audio to a file within the runner

• Buffer saving: save buffer contents to an audio file

• OSC Mapping: addresses no longer restricted, can map OSC to/from the runner interface itself

• Improved naming conventions

• Parameter Views: create subsets of parameters from multiple devices/instances, sorted as you please

• Graph Action Menu: save and reload improvements

• Auto-layout: automatically adjust graph layout

• MIDI Mappings View: list all MIDI mapped parameters and ability to remove or manually edit a mapping.

• Resources View: manage graphs, patchers and audio files on the runner

• Graphs tab: configure the Startup Graph (new, empty graph, last state, or a specific graph)

• Runner / Runner Dependency Updates: decoupled from RNBO Package releases and can be independently updated.

Binary Blobs in Presets

• buffer, data, list.reg, list.store: contents can now be saved in a preset

param~ Improved Feature Parity with param

• The functionality of these two objects are more aligned

codebox Improvements

• Lists can be initialized with size, fe: new List(74)

• consts can be used in other consts to set their values

• nocache setting to disable cache

rnbo.remote

• Max Param Connect support

RNBO Subpatchers

• #0 can be used for creating unique IDs.

Transport

• Improved lock behavior for phasor~ and metro (both in Max and in exported targets)

New Objects

• twist~ operator like the Max object to make curved ramps.

• presetbang object to report when a preset is being taken and applied.

• filtercoeff is now an operator and can be used in codebox / codebox~

Minimal Export

• A heavily reduced, engine-less C++ code export that is targeted to enable RNBO to run on small “bare metal” targets like Arduino Giga, Electrosmith Daisy and similar. Here is the documentation: https://rnbo.cycling74.com/learn/minimal-export

• Comes with these example projects:

  • RNBO Minimal Export for Bare Metal Targets: https://github.com/Cycling74/rnbo.example.baremetal

  • Example of how to use RNBO code on the Arduino GIGA R1: https://github.com/Cycling74/rnbo.example.giga

  • Example of how to use RNBO code on the Daisy Audio Platform: https://github.com/Cycling74/rnbo.example.daisy

• Enables the adaption of the Electrosmith oopsy platform for RNBO which is currently in beta testing: https://github.com/Cycling74/oopsy/tree/stb/RNBO
