This has nothing to do with NtEd! It is a problem of your MIDI device! All MIDI based applications (for instance kmid (not kmidi !!!) or pmidi) will fail!

First of all: Try to play a MIDI file with kmid (not (!!!) kmidi). As long as kmid does not produce any sound, NtEd (and any other MIDI device based software) will not produce any sound, too! The reason is: Either your soundcard has no hardware MIDI synthesizer or it has a hardware MIDI synthesizer but it is not supported by Linux.

Please refer to the ALSA project page to find out whether the midi device on your sound card is supported.

Before making a lot of effort to emulate the hardware synthesizer by software you should search for a soundfont file on the CD shipped with your soundcard. A soundfont file has the suffix .sf2 or .SF2. Please make sure it is a General MIDI soundfont! If there is such a soundfont file there is a high probability you simply have to load the soundfont onto your soundcard.

To to this you need a program called asfxload. Simply type:

asfxload <soundfont>.sf2

But even if you cannot find a soundfont file on soundcard CD, you can try to download a soundfont file. I recommand the soundfont mentioned at http://alsa.opensrc.org/8MBGMSFX.SF2.

If asfxload fails your soundcard does not permit loading a soundfont.

There is still a last chance that not all needed moduls are loaded. So as a last attempt type as root:

modprobe snd_seq_midi

and repeat the asfxload command.

If asfxload fails again you have to emulate the hardware MIDI synthesizer by software. This works if your computer has enough performance. Windows for instances starts a soft synthesizer automatically if the hardware synthesis does not work. So, be not confused if you can play MIDI files on Windows!

Such emulation software exists for Linux, too. But it is more complicated because:

But there is a (relatively bulky) way! See The TiMidity server detailed instructions!

Note! There are more software synthesizers on Linux, which can be tested. Among them the FluidSynth. See http://www.linux-sound.org for a list.

You have not installed the program! Please type (as root):

make install

Refer also to INSTALL file shipped with the nted-x.y.z.tgz archive.

You can use the --prefix option to install the NtEd in an arbitrary directory below your $HOME directory. Please refer also to INSTALL file shipped with the nted-x.y.z.tgz archive.

Furthermore, if you want to avoid the make install command then set an environment variable NTED_FONT_DIR to the directory where the nted/ntedfont.pfa is situated.

For instance, assume the ntedfont.pfa is at /home/smith/datafiles/nted/ntedfont.pfa type at command prompt:

export NTED_FONT_DIR=/home/smith/datafiles

if you have a bash or sh shell.

If you're using a csh or tcsh type:

setenv NTED_FONT_DIR /home/smith/datafiles

To find out your shell type:

echo $SHELL

at command promt.

That means you either have no ALSA sound system. Or you have an ALSA sound system but for complicated reasons your ALSA midi sequencer is not initialized. In many cases this is due to a missing module. Therefore try (as root):

modprobe snd-seq-midi

and restart NtEd.

You are a SuSE-Linux user! SuSE places this tool at /opt/gnome/bin. Actually this should be in your PATH. But under certain circumstances this is not the case. If so then make sure /opt/gnome/bin is in your PATH. If you have a (t)csh shell type:

setenv PATH "$PATH:/opt/gnome/bin"

If you have another shell type:

export PATH=$PATH:/opt/gnome/bin

To determine your shell type:

echo $SHELL

Ok, you can inspect the config.log. But this is presumably superfluous, because in most cases that means: You have no C++ compiler installed.
