AGS - Advanced Gtk+ Sequencer / Blog: Recent posts

fix version available 0.4.2-44

fix version follows.

The release date is due in 2 weeks, for now.

This means you invoke gsequencer for now. The name Advanced Gtk+ Sequencer stays still for the newly created libraries.

So it was said, Advanced Gtk+ Sequencer held its promise to split code into libraries. There still some work remaining to fix modularity but isn't much to do.

AgsApplicationContext super-seeds AgsMain and the header main.h will slightly change. The AgsMain struct will disappear and me appreciates those changes. Not at least cause of reversed words problematic.... read more

Hi community

Advanced Gtk+ Sequencer aka gsequencer will stop using automake since me feels really pissed off dealing with those unnecessary and frustrating build cycle.

Ever tried to do a recursive automake file at your flavors?

kindly yours

Months ago there was first announcement of ags 0.4.2. Since then many fixes towards stability and usage of the audio layer occurred.

The new release tries to keep such modifications low but rather improving GUI and user experience.

On-coming release will provide many new features like:

• effect bridge
• automation editor
• ladspa bridge
• pattern editor
• lv2 support

The effect bridge is a base class acting as channel container for providing ladspa effect's processors. You may have either dedicated or bulk mode.... read more

After a short development break work on Advanced Gtk+ Sequencer goes on ...

So far me did minor fixes to ags_channel_tillrecycling_cancel() this causes the matrix sequencer not crashing anymore.

Further introducing a global mutex ags_application_mutex intended for use especially with AgsMain or where you need something like global locking.

hot linking channels caused engine to crash, in some prior versions. Me can say at least it doesn't crash. but can't exactly say if it's operable since having only one soundcard connected. It is operable.

And for sure, no sound server connected ...

Further Advanced Gtk+ Sequencer is shipped with a sample file ags_file.xml and configuration ags.conf

So you might:

$ ./ags --filename ags_file.xml

To save plugins should be safe for now. Further previously mentioned removal of plugin is properly done.

In Advanced Gtk+ Sequencer 0.4.2-39 you may add recalls during playback. Caveat is as removing won't apply immediatly since the template got duplicated. This means remove eg. a LADSPA plugin just removes the template but not the running effect.

Further API documentation was updated see: http://ags.sf.net/api/ags

Advanced Gtk+ Sequencer definitively supports LADSPA. In earlier releases it was just rudimentary implemented and not functional at all.

And for now it's here.

Me trying to fix this issue.

Restore seems to work correctly there may be some warnings during opening files. But they can probably ignored. Further investigation by testing needed.

First tests seems to be satisfiable:

• Restore of editor
• Restore of engines
• Restore of links
• Restore of patterns
• Restore of notations
• Restore of ports

Missing tests:

• Restore of Plugins (may be broken) - definitively broken
• Is the entire engine fully operational... read more

XML IO was broken for Advanced Gtk+ Sequencer 0.4.2-20 to 0.4.2-31.

Fix version available 0.4.2-32 for now.

  PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
23263 h3lix    -96   0 1384m 777m  14m S 113.8  9.9  61:17.78 ags

and runs on ...

Advanced Gtk+ Sequencer version 0.4.2-28 is now running for over 1 hour and 30 minutes

  PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
18301 h3lix    -96   0 21.9g 6.1g 3840 S 111.3 79.3  99:28.05 ags

and runs on ...

The drum is functional again other engines may crash for 0.4.2-25.

Bugfixes are following.

affected function is probably ags_audio_open_files() during patching occured a mistake ...

Further API gets some modification file IO stays the same.

to be added:

• ags_line_map_recall()

and must be implemented by

• AgsPanelInputLine
• AgssMixerInputLine
• AgsDrumInputLine
• AgsDrumOuputLine
• AgsSynthInputLine

...

further find_port() in AgsMachineClass, AgsPadClass and AgsLineClass to be implemented

Note: Swami is missing in minos-one_v1.0.iso

Download http://sourceforge.net/p/ags/files/minos-one_v1.1.iso

The new release is based on systemd see http://www.linuxfromscratch.org/lfs/view/systemd/

Many new software added to minos-one_v1.0:

These features will be included for sure:

• Advanced Gtk+ Sequencer 0.4.2-21
• Swami
• fluidsynth
• LADSPA
• ffmpeg
• mplayer
• ...

Intended to be added:

Definitely added:... read more

Note there some problems with images ...

The official release will follow.

minos-one_v1.0

I just read dssi-vst supports LADSPA and brings those plugins to it ...

Note there will follow one more release that handles configuration correctly.

ags-0.4.20 and later should really have a config file like this one in ~/.gsequencer/ags.conf

It is documented in the wiki as well.

[generic]
autosave-thread=false

[thread]
model=multi-threaded
lock-global=ags-thread
lock-parent=ags-recycling-thread

[device]
samplerate=44100
buffer-size=940
pcm-channels=2
dsp-channels=2
alsa-handle=hw:0

No chance with VirtualBox to get desired performance. There will be provided an updated ISO which fixes soundcard rights in /etc/group.

Probably there will be a downgrade of ags-0.4.2-20 to ags-0.4.2-19 because it seems to be broken.

The live DVD works great with my 2 years old Lenovo Yoga Ultrabook :)

• systemd included thereby you get rid of the many error messages
• splash image replaced
• downgrade to ags-0.4.2-19... read more
