I have been trying to play some midi files using kmid. I always get the message "Can't open /dev/sequencer. It appears that some other program is using it." I have no other programs running and the ps command does not show any such processes.
I found that the /dev directory contains sequencer and sequencer2. I changed their permissions to rwx for u,g,o and it took effect.
But I still can't play my midi files.
Please help.
Thanks.
(My distro is RedHat 9)

have you got a maper installed? I know i can't play midis and don't have one but havent had time to look. If running KDE its under sound - sound system - midi - "Use a midi mapper" (bottom).

I wish to play a midi file, but playmidi does not work:

/home/rdn/music% playmidi pentatubes100.mid
Playmidi 2.4 Copyright (C) 1994-1997 Nathan I. Laredo, AWE32 by Takashi Iwai

open /dev/sequencer: No such device

This is the listing for /dev/sequencer
/home/rdn/xplore% ls -l /dev/sequencer
crw------- 1 rdn root 1 Aug 30 2001 /dev/sequencer

And the file type is:
/home/rdn/xplore% file /dev/sequencer
/dev/sequencer: character special (14/1)14,

Can someone give a usable explanation and a cure for this problem
(which I see several other people have reported.)

Thanks in advance,

Roger

i have the same problem: i can't play midi files. i've enabled midi mapper usage in control center, but it doesn't work anyway. i've tried to open kmid form konsole, and it was unable to open (it said that it's unable to read from libkmidlib). then i decided to uninstall kmid and install a newer version. i've downloaded kmid, but when i tried to install it, i met a dependencies problem. dependencies were to much. i also tried to install from source, but no results. what should i do?

thanks

what sound card ?

I had problems with kmidi in the fedoras. So did my friend who installed it on knoppix. I ended up using timidity, which works very nicely.

Just download timidity++ and install it. It plays midi files very well. I have given up trying to use kmid and kmidi.

my distro is SuSE 9.1 Pro
i don't have working midi mapper. in Control Center i've set to use it, but i can't play midi anyway. when i try to open /opt/kde3/bin/kmid from the Konsole, it gives me an error. this is my Konsole output:

i tried to reinstall kmid, but it gave me too much failed dependencies.

could anybody help me please? :/

I will repeat my advice. Install timidity++ and enjoy listening to your midi files.
