    Re: MIDI Software Synthesis

    Any suggestions on getting lmms or rosegarden4 or anything to play back with timidity? I have timidity running in a command window:

    timidity -iA -B2,8 -Os1l -s 44100

    and if I use kmid or pmidi, the file plays fine.

    If I use lmms or rosegarden4 I can't get anything to play. For example with lmms I get these errors:

    ALSA lib rawmidi_hw.c:231snd_rawmidi_hw_open) open /dev/snd/midiC0D0 failed: No such file or directory
    cannot open MIDI-device: No such file or directory
    Couldn't create MIDI-client, neither with ALSA nor with OSS. Will use dummy-MIDI-client.

    Thoughts?

    Thanks...

    I ran all the module commands and to play a file like timidity myfile.mid works great, but when i enter the line timidity -iA -B2,8 -Os1l -s 44100, I get a:

    Code:
    ALSA lib pcm_dmix.c:862:(snd_pcm_dmix_open) unable to open slave
    Can't open pcm device 'default'.
    Couldn't open ALSA pcm device (`s')
    So far I didn't experience any problems with the sound at all.

    thanks for help...

    problem was somehow solved by rebooting - now the server serves kmid without problems...

    Re: MIDI Software Synthesis

    I made timidity work without problems. Command timidity sth.mid works very good, but when I'm running some other program using midi (kmid for instance), it works very slow... How can I make it's performance better? I need midi support for some guitar programs.

    Thanks in advance.

    Aaron.

    Re: MIDI Software Synthesis

    How do I fix this?
    ubu32@ubu32-laptop:~$ timidity '/home/ubu32/Desktop/Midi/ATT10141414.mid'
    /etc/timidity/HSSynthCollectionI.sf2: Permission denied
    timidity: Error reading configuration file.
    Please check /etc/timidity/timidity.cfg
    ubu32@ubu32-laptop:~$

    Uh, you can just install Timidity and edit the /etc/default/timidity file, then run a "sudo /etc/init.d/timidity start" if you want to run Timidity as a daemon.

    Doesn't anyone ever check this stuff out?

    Also, if you have the lowlatency kernel, I recommend trying QSynth, a nice FluidSynth GUI.

    I followed the HOWTO to the letter.....I thought.

    lowlatency kernel,
    Huh?

    Somehow I get the feeling I was RTMFed

    I was saying the HOWTO is by FAR NOT the easiest way to have Timidity running as a daemon.

    Well, if you install the package "linux-lowlatency" and reboot, you can have smoother MIDI performance. And you can install "qsynth" and get a nice GUI for FluidSynth. I have switched to FluidSynth because it sounds better than Timidity if you have the lowlatency kernel.

    If you want to use SoundFonts, you definitely want to use qsynth/fluidsynth instead.

    McTek, your problem is that you are not able to read the sf2 file. Try this command:
    Code:
    sudo chmod a+r /etc/timidity/HSSynthCollectionI.sf2
    to fix this and allow all users to read it.

    Re: MIDI Software Synthesis

    The path to the eaw-patches has changed, there was an update.

    It should now read:
    sudo vim /etc/timidity/timidity.cfg
    Code:
    dir /usr/share/midi/eawpatches

    Sorry, can you be more clear? I don't understand. I only got freepats working.

    Thanks
