Re: [Rosegarden-user] New version?
Hello all, I apologize in advance for not being able to provide more details right now. I'm not near the machine where I did this on. I found a hack to allow MIDI export to work. In one of the modules there are note off events removed, with a comment something to the effect of "remove any previous note off events for this note" (heavily paraphrased). It traverses a datastructure and removes some note off events. This is in a function, underneath another line or two of code that does something else with note-off events. If you disable the lower section of code which removes note off events in this single function then MIDI export appears to work correctly. At the very least, there are no more stuck notes. I was working with an SVN version from about a month ago. This is almost assuredly not the right way to fix the problem, as the code to remove note offs looks like it was put there on purpose. But it may give a hint towards a proper fix to someone with more Rosegarden knowledge than me. Again, sorry for the lack of specifics. If there is interest I can look up exactly what I did in a couple of days and report back to the list. Or maybe it is already fixed correctly, which would be the best case. I'm not able to update from SVN right now so I can't check. -Michael J. Wilson D. Michael McIntyre wrote: > On 11/29/2012 01:12 PM, Brett McCoy wrote: >> Is the export fixed in svn version, I wonder?

I'm hearing it start low > and rise, per the controllers. As I understand it, this test wouldn't show the problem I'm experiencing. The following modification will show it: 1. New doc with track 1 set to "fixed" per default 2. Draw segment A 3. Draw segment B, overlapping about halfway 4. Put some random notes in segment A 5. Set top level Instrument Parameters volume to 100 6. Put a single volume controller in segment A at 50, somewhere before the start of segment B 7. Put any CC in segment B besides volume (it seems like if there are no events in segment B it is skipped) 8. Hit play Expected outcome: Volume starts loud (100), then gets softer (50) and does not change again. Actual outcome (12.04): Volume starts loud (100), then gets softer (50), then gets loud again (100) at the start of segment B. The reason the test you described wouldn't show the issue is because the top-level value and the first value in segment B are the same. There are actually two issues: 1) The top-level value is sent at the start of every segment if the controller is not hidden, instead of just the start of playback (this may make sense in auto mode but I don't think it makes sense in fixed mode). 2) If the volume or pan controllers are hidden, then the .rg file saved and reloaded, they are re-enabled somehow. I haven't looked into this as much. For my purposes, fixing 1) would make 2) not important to fix. I was only hiding these controllers to try to work around 1). > Nobody has packaged 12.12.

I am in the middle of a big move so it will probably be a couple of weeks before I get a chance to play with the development version. I will report back here when I do. I know you are extremely busy and I appreciate you taking the time to look into this. -Michael J. Wilson -- Everyone hates slow websites. So do we.

Re: [Rosegarden-user] auto channel takes over and re-activates automatically
I'd like to add that, at least in 12.04, an "all controllers reset" as well as any visible controllers in the Instrument Parameters box are sent at the start of each segment. I have some compositions that use separate overlapping segments in the same track for control data and notes, and the result is that in recent versions of Rosegarden the volume and panning get reset to their default values every time a new segment starts, sometimes during the middle of another segment on the same track. I tried to work around this by removing all the controllers from the Instrument Parameters pane via the Manage MIDI Devices dialog. But it seems like if the Volume and Pan controllers are hidden in this way then they are silently added back when the .rg file is saved, Rosegarden is closed, and then Rosegarden is launched again and the file re-opened. If I import a saved .rgd file with all controllers hidden every time I open the project then it seems to behave the way I want it to; that is, individual controller default values are no longer sent. The "all controllers reset" message is still always sent, however. Maybe in "fixed" mode the default values and all controllers reset should not be sent at the start of each segment, but just at the start of playback? This would maintain legacy behavior for people using fixed mode, although it may have implications for drum tracks which I think currently default to fixed. It makes sense to send the controllers for each segment in "auto" mode, because the new MIDI channel is probably not initialized for that track yet. I understand that I may not be using segments the way they are intended to be used, but I appreciated the ability to do this in previous versions! Thank you, and sorry to go off on a tangent (also apologies if this has already been fixed; my distro hasn't packaged 12.12 yet). -Michael J. Wilson -- Everyone hates slow websites. So do we.

I'll take a shot at describing how to use Qsynth as an external
application. This works for me with Rosegarden 12.04 and Qsynth 0.3.6
on Fedora 17.
1) Close any other programs you might be running
2) Start Rosegarden
3) Start Qsynth
4) In Qsynth, click on "Setup" and make sure "Enable MIDI Input" is
checked in the MIDI tab, that "jack" is selected as the Audio Driver in
the Audio tab, that "Auto Connect JACK Outputs" is checked in the Audio
tab, and that a soundfont is listed in the Soundfonts tab. If you have
to change any of this you might have to close and restart both programs
before going on.
5) In Rosegarden, load the project you want to work on. Click on Studio
-> Manage MIDI Devices. In the dialog that pops up, in the top-left box
("MIDI Playback") there should be something that says "General MIDI
Device" - click on this. To the right of this there should be something
that says something like "Synth input port" - this is the Qsynth MIDI
input. Click on it. Click the "Close" button.
6) Now the MIDI data from Rosegarden should be sent to Qsynth when you
hit play in Rosegarden, and Qsynth should play sound through your soundcard.
What should be happening if you follow these steps is when you launch
Rosegarden, it will start the Jack audio server. Then when you launch
Qsynth it should connect to the physical outputs on your soundcard via
the already-launched Jack server. Rosegarden will handle making the
correct MIDI connections through its studio manager. Soundfonts are
loaded in Qsynth, and other work on your piece is done in Rosegarden.
I would recommend installing qjackctl and using it to manage your audio
and MIDI connections between different applications. You can also use
it to start the Jack audio server with different parameters (do this
before launching either Rosegarden or Qsynth).
You can also host fluidsynth-dssi directly in Rosegarden. In my
experience, sometimes the editors will not launch for DSSI plugins
unless you modify some network settings (this is not an issue with
Rosegarden) and I don't remember what I had to do last time I had it
working. You will need to be able to launch the editor to select a
soundfont.
If you want to try this, select a track in Rosegarden by clicking on the
name of the track. In the "Special Parameters" box, under "Track
Parameters" click the "Device" drop-down and select "Synth Plugin" to
make that track use a plugin. Then, under "Instrument Parameters" click
the button that says "" and, in the dialog that pops up, click
in the "Plugin" drop-down and select FluidSynth DSSI Plugin (or another
plugin if you wish). I believe Rosegarden will automatically connect
the audio outputs, but you can use qjackctl to verify this.
Good luck!
