MusE-2.2 is released
MusE 2.2 - 2015-01-06

Hi All!

Following our plan of making monthly releases. Ah, I mean yearly releases...
Well, actually, it's been nearly two years since last stable release. Sorry.

Here we are anyway with a new release of MusE, and we think it's a good one!
Since last we have moved to github and Andrew has joined the team to, among 
other things implement LV2 support, which he has done excellently. We are
quite happy with the current state and music has been recorded with MusE like 
never before, some demonstrations are listed below.

Major feature improvements of this release includes:

* Support for LV2 Synths and effects
  - effects are supported both in Effect rack and in Arranger
  - State interface
  - Worker interface.
  - Instance-access.
  - KX studio Programs interface + extended programs interface to support 
    per-channel bank/patch change (only Yoshimi now supports this feature).
  - Common must-have features: Atom, buf-size, event, options, uri-map, urid.
    + Other extensions: CV type lv2 ports
    + LV2_TIME__Position
    + Atom_Event_Transfer support for plugin<->UI communication
    + LV2 path MAP and MAKE extensions
    + LV2 LOG extension
  - UI interface. Supported UI subtypes:
    + QT4
    + GTK2
    + GTKMM2
    + X11
    + External interfaces (from kx studio specs).
    + idle callbacks
* Yet another MAJOR audio engine and plugin/synth process chain re-write
  - Track controllers (vol, pan) now sample-accurate and near noise-less

Numerous bug fixes and minor enhancements:
  - Metronome with accent clicks and replaceable clicks
  - Synths rearranged in separate menus
  - Reworked the PluginDialog to use a ui file and give more filter 
  - Added [HOME] button to file open dialog
  - Ignore undo/redo while recording
  - Fix crash reported by LakeIshikawa: Pressing delete while clicking or 
    dragging events or parts
  - Fixed copy/paste problem: Paste copies not clones, if the original 
    parts/tracks have been deleted.
  - More commands support Undo/Redo, like setting global tempo. 
  - Some new scripts, RemoveAftertouch, TempoDelay
  - Fix song not 'dirty' on many operations (close was not prompting to save).
  - Instrument Editor now basically complete: Added Initialization Sequence 
  - Sysex event editor now allows selection from pre-defined Instrument Sysex 
  - Revised and edited Roland SD-50.idf by Patrick (split into GM2/nonGM2). 
  - MusE now imports GM2 midi files. (Properly selects GM2 instrument.)
  - Added a visual metronome to Bigtime
  - Added line drawing of tempo in graphical master track editor
  - Fixed bug (issue #342 Moving Aux sends crashes muse)
  - Added more keyboard shortcuts in midi editors
  - Mods/fixes to Midi Input Transformator plugin:
  - When midi in is enabled in drum editor the selected track is moved along 
    with the triggered key
  - Fixed bug with playback of drums clicking on notes in the new drum editor, 
    it was playing the wrong instrument
  - MESS synths (esp Deicsonze): Controls (like Track Info program) and synth
    controls now mirror each other, both ways.
  - Deicsonze softsynth: Fixed: Not remembering settings + ladspa plugin 
    settings, midi controllers moved to NRPN14 type.
  - Native VST: Call idle periodically. Makes some plugins like Glitch work, 
    as per LAD mail.
  - Change window title when there are unsaved changes
  - Add auto-save feature, when enabled tries to save after 5 minutes
  - Added pitch control to SimpleDrums, first version
  - Fixed Ctrl+arrows in the arranger so the track list is scrolled

Happy new year from the MusE Team!
Hi, thanks for new release, just installed it from kxstudio repositories, the logo window appears, then gui window shortly starts and fades away, looks like invalid window parameter or something. I am on kde ubuntu. Probably I have to post this to kxstudio forum?
Hi edvo,

Sounds wierd, please try starting muse from a terminal, hopefully there is some error message pointing to why it fails. You can post the info from the terminal here.

Do post it to the kxstudio forum also, to make sure it's not a build issue with the kxstudio release.
Thanks spamatica, when starting muse in console, the ending lines are these:

The program 'muse' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 1770 error_code 3 request_code 20 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Segmentation fault
Hi again, in KXstudio forum talkTX pointed that he gets the same errors and suggested :
muse -style plastique
This starts muse without problems Smile

Great! Do you know what style it is that causes it to fail?
We could try reproduce the problem and see if it is fixable.

I found out that if I upgrade the muse and start it in terminal without style option, it crashes. But as I started it with plastique style option, now it works, I can start it without style option, or with any style. So some initial settings are wrong, maybe this is related with upgrading from earlyer version of muse.
