Installing OB-Xf

Section titled “Installing OB-Xf”

Windows

Section titled “Windows”

On the Windows platform, OB-Xf installs optionally as:

  • 32-bit VST3, with filename OB-Xf.vst3
  • 64-bit VST3, with filename OB-Xf.vst3
  • CLAP plug-in instrument, with filename OB-Xf.clap
  • Standalone executable, with filename OB-Xf.exe

System Requirements:

  • Windows 7 or newer
  • A reasonably fast CPU (Pentium 4/Athlon 64 or above)
  • At least 4GB of RAM
  • VST-compatible host application

To use the 64-bit version on Windows you also need:

  • A CPU supporting the x64 (AMD64/EM64T) instruction set
  • A 64-bit version of Windows
  • An application to host 64-bit VST/CLAP plug-ins (for plugin versions)

VST3 and CLAP versions of the plug-in install to default plug-in locations. If your host application does not find OB-Xf, check that your application supports VST3 or CLAP, and make it scan for plugins.

macOS

Section titled “macOS”

On macOS, OB-Xf installs as a 64-bit Plug-in Instrument for the Audio Unit (AU), VST3, and CLAP plug-in interfaces, and as a standalone application.

System Requirements:

  • Mac OS X 10.11 or newer
  • A 64-bit x86 Intel or ARM Apple Silicon CPU
  • At least 4GB of RAM
  • 64-bit AU, CLAP or VST-compatible host application (for plugin versions)

To install OB-Xf, run the packaged installer. You have the option to install AU OB-Xf.component, VST3, and CLAP, along with factory patches and wavetables. The packaged installer installs OB-Xf for all users of your system.

Linux

Section titled “Linux”

On Linux, OB-Xf is available as a 64-bit VST3 and CLAP as a deb and RPM package. It is also offered as a standalone application.

The system requirements can be hard to determine, as there are many Linux distributions, and other factors.

The installation package on the OB-Xf website is a Debian package.

The distribution package is built on Ubuntu 18.04.

A list of required packages is listed in the source and in the deb file.

Standalone Version Options

Section titled “Standalone Version Options”

If you are running OB-Xf as a standalone executable, options at the top-left:

  • Configure MIDI and audio inputs and outputs
  • Save and open state files for the synth
  • Reset OB-Xf to the default state

The BPM setting is to the left of the virtual keyboard at the bottom of the window. This sets the tempo for parameters that can be tempo-synced.
