Play a midi file, showing how it should be played on a piano

PIANOGUI

Pianogui is a simple application that let's you play a midi file, or a midi input, and shows how it should be played on a piano. Pianogui is the "graphical" equivalent of Pianoterm

Below is a screenshots of the main window.

Build dependencies

Pianogui requires a C++14 compiler to build. (g++ 5.3 and clang++ 3.6.2 work both fine). It also depends on the following libraries:

• libRtMidi
• Qt

Also note that pianogui does not play music itself. Instead it relies on a system-wide midi sequencer. On GNU/Linux you might consider installing timidity

On debian, one can install them the following way:

sudo apt-get install timidity librtmidi-dev librtmidi2 libqt5widgets5 libqt5gui5 libqt5core5 qt5-default qt5-qmake g++-5,3

Compiling instructions

Once all the dependencies have been installed, you can simply compile pianogui by entering:

make

This will generate the pianogui binary in ./bin

How to use

Pianoterm needs a midi sequencer. If you decided to use timidity, you will need to run it first using:

timity -iA &

Then you can run the application by typing

./bin/pianogui

This will open an a window showing a piano keyboard. On the "output port" menu, you can select the midi sequencer like TiMidity xxx:0. On the "input" menu, you can either select an input keyboard (e.g. a virtual midi keyboard player)

or you can play a midi file by choosing select file in the input menu, or using the Ctrl + O shortcut.

When playing a midi file, one can play/pause it using the space key, or the Ctrl + P shortcut.
