SendMixer

A stereo channel strip plugin with one master gain and two pre/post-fader sends

Usage

Here is an example of how SendMixer is used in Carla to provide a reverb aux bus for a synthesizer plugin:

Formats

This plugin comes in the following plug-in formats:

LADSPA (sendmixer-ladspa.so)
LV2 (URI: https://chrisarndt.de/plugins/sendmixer)
VST2 (sendmixer-vst.so)

The plugins depend on the host to provide a generic UI to control parameters.

Compiling

Make sure you have installed the required build tools and libraries (see section "Prerequisites" below) and then clone this repository (including sub-modules) and simply run make in the project's root directory:

$ git clone --recursive https://github.com/SpotlightKid/sendmixer.git
$ cd sendmixer
$ make

Installation

To install all plugin formats to their appropriate system-wide location, run the following command (root priviledges may be required):

make install

The makefiles support the usual PREFIX and DESTDIR variables to change the installation prefix and set an installation root directory (defaulty: empty). PREFIX defaults to /usr/local, but on macOS and Windows it is not used, since the system-wide installation directories for plugins are fixed.

Use make's -n option to see where the plugins would be installed without actually installing them.

You can also set the installation directory for each plugin format with a dedicated makefile variable.

LADSPA: LADSPA_DIR (<prefix>/lib/ladspa)
LV2: LV2_DIR (<prefix>/lib/lv2)
VST2: VST_DIR (<prefix>/lib/vst)

Example: make DESTDIR=/tmp/build-root VST_DIR=/usr/lib/lxvst install

To install the plugins only for your current user account, run make install-user.

Again, you can also set the installation directory for each plugin format with a dedicated makefile variable.

LADSPA: USER_LADSPA_DIR ($HOME/.ladspa)
LV2: USER_LV2_DIR ($HOME/.lv2)
VST2: USER_VST_DIR ($HOME/.vst)

Note: The given default values for all of the above listed environment variables differ depending on the target OS.

Prerequisites

The GCC C++ compiler, library and the usual associated software build tools (make, etc.).

Debian / Ubuntu users should install the build-essential package to get these, Arch users the base-devel package group.
patch
pkgconf
The faustpp pre-processor and FAUST (optional)

The LV2, LADSPA and VST2 (vestige) headers are included in the DPF framework, which is integrated as a Git sub-module. These need not be installed separately to build the software in the respective plug-in formats.

faustpp and FAUST are only needed to re-generate C++ source and headers files if the FAUST DSP source files in the faust directory are changed.

Author

This software was created by Christopher Arndt.

Acknowledgements

The DSP code is generated from the FAUST sources via the faustpp pre-processor.

The project is built using the DISTRHO Plugin Framework (DPF) and set up with the cookiecutter-dpf-faust project template.
