Running EasyABC in Linux
There is no install or binary package for EasyABC on Linux. You
will have to run it from source code and install the external
executables called by EasyABC.
EasyABC is written in Python and wxPython and requires the additional
programs abcm2ps, abc2midi and abc2abc too in order to run.
Please note that if you wish to run Nils Liberg's original
version, EasyABC 1.3.5, you will need to find an old version of
abcm2ps.
EasyABC has migrated from Python 2 to Python 3. Python 2 is no longer supported.
easy_abc.py expects to be started from it's installation directory
in order to find its data files. If you start it from some other working
directory, then you need to set the EASYABCDIR environment variable
to point to the installation directory.
EasyABC supports both FluidSynth 2 and the mediaplayer from wxPython, but most users report problems with the wxPython player.
We have tested EasyABC on Linux Mint 20 using Virtual Box 6.1 and on a Raspberry Pi
The steps we had to do are as follows:
sudo apt install abcmidi abcm2ps fluid-soundfont-gm python3-wxgtk4.0 python3-pyparsing
unzip Downloads/EasyABC-master.zip
mv EasyABC-master/ EasyABC
sudo apt install libfluidsynth2
If that fails because the package does not exist yet then download the source code from:
https://github.com/FluidSynth/fluidsynth/releases
tar -xvzf Downloads/fluidsynth-2.2.3.tar.gz
cd fluidsynth-2.2.3/
mkdir build
cd build
sudo apt install cmake libgtk2.0-dev libpulse-dev
cmake ..
make libfluidsynth
cp src/libfluidsynth.so* ~/EasyABC
cd ~/EasyABC
python3 easy_abc.py
(If you get a GStreamer or wx.media error it means that FluidSynth failed to initialize. Then either FluidSynth library or SoundFont can not be found.)
Then choose a soundfont in Settings -> ABC Settings -> File Settings -> soundfont
You can find one here: /usr/share/sounds/sf2/FluidR3_GM.sf2
Now exit and run EasyABC again to use FluidSynth as the mediaplayer.
Some packages are not really needed:
If you want to use the wxPython mediaplayer instead of FluidSynth:
sudo apt install python3-wxgtk-media4.0
If you want to use MIDI recording:
sudo apt install python-wxtools python3-pygame
--------------------------------------------------------
Running EasyABC
Once EasyABC is running for the first time, it will search for
abcm2ps, abc2midi, and other executables in the /usr/bin/ and
/usr/local/bin folders. If it does not find these executables,
a message will pop up. If these executables are already on your
system, you can tell EasyABC where to find them by going
to the menu item, Settings/ABC Settings and then selecting File Settings.
--------------------------------------------------------
Using more recent version of abcm2ps or abc2midi
Though abcm2ps, abc2midi, and other related programs may come
with your current linux distribution, they are probably old
versions and you should get more recent versions. Source code
can be found on the web sites.
http://moinejf.free.fr/ and http://ifdo.ca/~seymour/runabc/top.html .
Binaries and Debian installs can be found in the abcplus web page
http://abcplus.sourceforge.net/
which is maintained by Guido Gonzato.
If you have obtained the source code to abcm2ps and the abcmidi package
then you will need to uncompress the zip file, cd into that directory
and run:
./configure
make
make install
--------------------------------------------------------
External MIDI player
It is very convenient to run Linux on a virtual machine on the
Windows host using Oracle's VirtualBox. This way you can avoid
disk partitioning and finding all the drivers for your graphics
and audio card.
If you cannot get the sound to work or do not want to use score following you can
use an external program like TiMidity.
On Linux Mint, we installed TiMidity, timidity-interfaces-extra, and freepats.
If your package manager does not find TiMidity, you can find it on
http://sourceforge.net.
Recent versions of TiMidity may not run correctly on your system
and it may be necessary to reduce the period
size from the default of 8192 down to 2048, using the runtime
option -B 16,9. (16,10 works on Linux Mint Cinnamon edition but not on Mate.)
If the period size is too large, data overrun may occur (you can
verify this by running TiMidity in verbose mode) and a MIDI file
will play too fast. Some discussion may be found on
https://sourceforge.net/p/timidity/mailman/
To get TiMidity working with EasyAbc, go to Abc Settings/File Settings
and set the midi player to /usr/bin/timidity and the Extra Midi Player
parameters to -B 16,9 -ig. The -ig will run timidity with a user interface,
allowing you to stop the player.
The freepats soundfont is rudimentary and rather incomplete but
sufficient to get you started. We recommend that you install one of
the free soundfonts that you can download from
http://coolsoft.altervista.org/en/virtualmidisynth
You should put the soundfont in /etc/TiMidity/ folder and modify
the timidity.cfg file so that it points to the desired soundfont.
We understand that TiMidity can be run as a virtual MIDI player using
the -iA option. Explanations on how to set this up is given in the
web pages:

-----------------------------------------------------
Other stand alone programs coming with EasyABC:
midi2abc.py can invoked like a standalone program:
python pymidi2abc.py <options>
[-f] <input file>
-o <output file>
-k <key signature> key name, or -6 to 6 sharps
-l <default note length (L: field)>
-m <time signature>
--nbb no beam breaks
--aux=<denominator of L: unit length>
--nt Do not look for triplets or broken rhythm
--s8 insert slurs on groups of 8th notes
--s16 insert slurs on groups of 16th notes
--bpl=<number> of bars printed per line
--title=<string> Adds T: field containing string
--origin=<string> Adds O: field containing string
Here is an example:
python midi2abc.py -f mymidifile.mid -l 1/8 -m 4/4
-----------------------------------------------------
xml2abc_nils.py can also be invoked like a standalone program:
python xml2abc_nils.py mytune.xml
Please note that Nils' xml2abc converter is now largely superceded by the, more powerful, one:
