mod-midi-merger

A small Jack-internal client to merge MIDI events from several inputs to one output.

When a new port is registered at the Jack server, this client will connect to it, if

• it is a MIDI port with outgoing events
• the name does not start with effect_
• if it does not belong to itself

Build

$ mkdir build && cd build
$ cmake ..
$ make

to install the shared library in /usr/lib/jack/mod-midi-merger.so run

$ make install

Usage

You can start mod-midi-merger-test for a normal Jack client or load mod-midi-merger.so as an internal client. Either way it shows up as:

$ jack_lsp --aliases
...
midi-merger:in
   MIDI in
midi-merger:out
   MIDI out

Advanced

Advance build usage examples:

$ cmake -DCMAKE_BUILD_TYPE=Debug

or

$ cmake "-DCMAKE_C_CLANG_TIDY=/usr/bin/clang-tidy;-checks=*" ..
$ make
