MusE --- Linux Music Editor
====================================================================
Welcome to MusE, the open source MIDI/Audio sequencer.
MusE is distributed under the GNU General Public License (GPL).
Please check out the file COPYING in this directory for more
details.
,-----------------------------------------------------------------.
| NOTICE |
|-----------------------------------------------------------------|
| Some parts of MusE code are EXPERIMENTAL, and may well result |
| in a CRASH, and who knows what other ill effects. |
| RUN THIS SOFTWARE AT YOUR OWN RISK. |
`-----------------------------------------------------------------'
=============================
Requirements:
=============================
- doxygen
www.doxygen.org
- CMake >= 2.4
http:/www.cmake.org/HTML/Download.html
- QT: Qt >= 4.2.0 (development files)
http://qt.nokia.com/products/
MusE does _not_ compile with older versions
- gcc >= 4.x.x or clang >= 2.9
http://gcc.gnu.org/
http://clang.llvm.org/
- libsndfile >= 1.0.1 (development files)
http://www.mega-nerd.com/libsndfile/
- libsamplerate >= 0.1.0 (development files)
http://www.mega-nerd.com/SRC/
- JACK >= 0.103 (development files)
http://jackaudio.org/
- libuuid (development files)
e2fsprogs package http://e2fsprogs.sourceforge.net/
Some distros may include it in another package such as 'libuuid', or offer a choice.
Optional:
- fluidsynth >= 1.0.3 (formerly known as iiwusynth) (development files)
http://sourceforge.net/apps/trac/fluidsynth/
- liblo Lightweight OSC (Open Sound Control) (development files)
http://liblo.sourceforge.net/
- DSSI Disposable Soft Synth Interface (development files)
http://dssi.sourceforge.net/
(Both recommended - DSSI alone will have no native GUIs, OSC alone does nothing, for now.)
- dssi-vst Support for DSSI vst plugins
http://www.breakfastquay.com/dssi-vst/
- LASH Audio Session Handler
http://lash.nongnu.org/
Recently LADISH has been emulating it instead:
http://ladish.org/
- ConTeXt (for building documentation, by default the build
script tries to build documentation, can be
disabled by setting ENABLE_DOCUMENTATION to OFF)
=============================
Building MusE:
=============================
- Download source from http://lmuse.sourceforge.net/
- Unpack the source somewhere.
You may also try the various MusE development SVN branches for
up-to-the-minute features and fixes, but they may be less stable.
- To compile MusE, run the following commands from the
top level directory where the source code was unpacked
(the directory where THIS README FILE is found):
******************************************************
* Notice: *
* A quick way is to run the ./compile_muse.sh *
* script in the same dir, it should perform the same *
* steps for a basic setup without asking any *
* questions. If it fails you may be better off using *
* the instructions below. *
******************************************************
The build directory:
--------------------
Building in a subdirectory is recommended to keep the build directory separate from the source tree.
So create a new subdirectory with a useful name like "build" or "debug" or "release":
mkdir build
Change directory (cd) to the new directory:
cd build
Configuration:
--------------
There are a few different ways to configure (notice the two dots):
Type "cmake -i .." to run in step-by-step 'Wizard' mode, this is the RECOMMENDED way to
setup the build environment.
Or type "cmake -L .." to see options, then compose "cmake <options>" yourself.
Some <options> are:
-DCMAKE_BUILD_TYPE=<type>
<type> can be blank (to reset a previous cached type to 'empty'),
debug, release, RelWithDebInfo and MinSizeRel.
Release is recommended, to get optimizations.
If no CMAKE_BUILD_TYPE is given at all, cmake uses either the previous
cached value, or else 'empty' (plain or default system optimizations).
-DCMAKE_INSTALL_PREFIX=<prefix>
The installation <prefix> where the program is installed.
The default is to install in /usr/local.
Or type "ccmake .." (if you have it - text-mode GUI). It may be blank so hit
'C' to first-time configure. Fiddle with yer options if ye so desire, then hit
'C' to configure then 'G' to generate and exit, or 'Q' to quit without
generating.
Or there is also a desktop GUI for cmake called cmake-gui.
Compiling:
----------
After configuration, while still in the build directory,type:
make
Installing:
----------
After compiling, type:
make install (as root)
or
sudo make install
=============================
Running MusE:
=============================
Recommended setup:
------------------
MusE is a realtime program which requires special rights to work properly.
- Check if you are running a sufficiently new linux kernel > 2.6.x
A modern, standard destop kernel might suit your needs.
However, for the best performance a so-called 'low latency' or 'realtime'
kernel may be required. Check your distro's packages for availability.
- create an "audio" group if it does not already exists
and put yourself into this group
- For realtime priority, you may want to ensure either the file:
/etc/security/limits.conf
or
/etc/security/limits.d/audio.conf
contains:
@audio - rtprio 95
@audio - memlock unlimited
- make sure you can acces the realtime clock (RTC)
chmod 660 /dev/rtc
chgrp audio /dev/rtc
- make sure MusE can set the rtc clock:
echo 8192 > /proc/sys/dev/rtc/max-user-freq
inspect with:
cat /proc/sys/dev/rtc/max-user-freq
- some distros do not load the alsa sequencer module by default.
if necessary, load the alsa sequencer module with:
/sbin/modprobe snd-seq
- Start jack, typically by using the qjackctl application.
MusE can also be run without Jack. MusE will use a dummy audio
driver if Jack is not detected, or the -a option is given.
Running:
------------------
start MusE by typing:
muse2 <options>
Some <options> are:
-h help
-v print version
-d debug mode: no threads, no RT
-D debug mode: enable some debug messages
specify twice for lots of debug messages
this may slow down MusE massively!
-m debug mode: trace midi Input
-M debug mode: trace midi Output
-s debug mode: trace sync
-a no audio
-P n set audio driver real time priority to n
(Dummy only, default 40. Else fixed by Jack.)
-Y n force midi real time priority to n (default: audio driver prio +2)
-p don't load LADSPA plugins
-I don't load DSSI plugins
-L don't use LASH
-l xx force locale to the given language/country code
(xx = de,en,es,fr,pl,ru,sv_SE)
(JACK and all its clients (qjackctl & MusE) must run with the
same user id)
=============================
known bugs
=============================
- not so many: only some usability quirks we're working on currently
- automation recording displays odd things in the arranger
while recording; the display is corrected once recording is
complete.
====================================================================
Let us know whether MusE works for you !!!
