A collection of MIDI filter, generator and processor plugins

Plugins

MIDI CC Map X4 - Map a single input CC to up to four output CCs.

MIDI CC Recorder - Store received Control Change messages and replay them when triggered.

MIDI CC to Pressure - Convert Control Change messages into (monophonic) Channel Pressure (Aftertouch).

MIDI PB to CC - Convert Pitch Bend into Control Change messages.

MIDI Pressure to CC - Convert (monophonic) Channel Pressure (Aftertouch) into Control Change messages.

MIDI Sys Filter - Filter out MIDI System Messages.

Plugin Formats

The plugins are available in the following formats:

• LV2
• VST2

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/midiomatic.git
$ cd midiomatic
$ make

Installation

To install the plugins system-wide, run (root priviledges may be required):

make install

The usual PREFIX and DESTDIR makefile variables are honoured to change the prefix directory (default: /usr/local) and the installation destination (for distribution packaging).

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

• LV2: LV2_DIR (<prefix>/lib/lv2)
• VST2: VST_DIR (<prefix>/lib/vst)

Example:

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

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

To install the plugins under your user's home directory, run:

make install-user

No special makefile variables are used in this case.

Prerequisites

• Git

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

  Users of Debian / Ubuntu Linux should install the build-essential meta package to get these, Arch Linux users the base-devel package group.

• pkgconf

Optional (only needed for checking plugins after building them):

• lv2lint
• KXStudio LV2 Extensions

For some reason PortGroup only appears in *.patch files.

Static allocation of ParameterEnumerationValue

From IRC:

strogon14: your PluginMIDISysFilter::initParameter leaks memory. please use static array instead of allocating memory there

I have to admit, my knowledge of C++ is very rudimentary, so I'm not sure what the correct way to do this is.

@falkTX: Any examples of the correct usage I could look at?
