[Rosegarden-user] Questions about audio playback and MIDI connections
Hi, I now use Rosegarden 20.06 on Ubuntu Studio 20.04 (xfce desktop environment) without major problem but I still have some questions about things that have worried me for a long time: 1) While using Rosegarden, I cannot play a video on Youtube, or play a piece of music using Parole Media Player. The only way I know to work around this is to change the settings of QjackCtl: Execute script after Startup: a2jmidid -e & Execute script on Shutdown: killall jackd It works, but I'm not very sure what it does, and above all I wonder if there is not an easier way? 2) Each time the PC and Rosegarden are restarted, I have to check and change my MIDI connections because the MIDI ports of my external USB sound modules are systematically inconsistent (MIDI Playback devices related to MIDI Outputs). I believe Rosegarden has an internal function for "smartly" attaching a MIDI device, according to its name, but it doesn't work for me. Surely I must miss something but what? Is there anything to add to the .rgd file? For example I have already seen something like this, which uses the keyword "connection": connection="72:0 XV-2020 MIDI 1 (duplex)" type="midi"> But since the port number can change at each boot, or depending on the order in which the devices are turned on, maybe this is not a good method? 3) And by the way, where can we find a complete manual about the xml format of .rgd files?

[Rosegarden-user] OT (for the debian-list): Re: Questions about audio playback and MIDI connections
(Intentionally cross posted) The following quotes are from an email to a rosegarden mail list -- Rosegarden is a music notation (mcow) program. A user is describing a problem in which it appears the MIDI ports (connected via USB ports) change on each boot (or maybe even each start of the Rosegarden program). I just wondered if this is similar to the current Linux behavior related to disks wherein, in the old days, disks came up in a consistent order, but nowadays (maybe because of systemd?) they (or some of them) can start in parallel and thus their device numbers are not consistent. If a similar problem does exist with USB ports, is there a way to force them to be identified in a consistent way on each boot (i.e., something like using UUIDs or labels for disks)? Thanks!

Re: [Rosegarden-user] Add Control Ruler not working as expected in Matrix Editor and a few other questions
On 6/29/20 4:41 AM, Hugo van Galen wrote: I have been using Rosegarden for about a decade now and have been able to figure it out using search engines. Lately I ran into an issue that I don't remember having before: I noticed that, when in the Matrix Editor, the option "View / Rulers / Add Control Ruler / Volume Controller" doesn't do anything; yet when in the "Notation Editor" this works fine. I can't reproduce this. But the code does look like it needs some review. The issue will likely become apparent upon cleaning up and syncing the relevant routines. It seems that any other controller except Velocity and Pitch bend only work in the Notation Editor. Those are handled separately, so it isn't surprising they are not affected. Is there an underlying logical reason for this to behave this way -- or is this a bug? Sounds like you've found a legitimate bug. The key routines in question are: MatrixWidget::addControlRuler() NotationWidget::slotAddControlRuler() There are differences that need to be resolved between those two and that might clear up the issue. I don't have time at the moment, but should be back to Rosegarden this weekend. I will have a look then. - I also wonder whether it is already possible to "remember" the zoom options for any given segment as I always find myself tweaking these, the default zoom doesn't work for me here. Or am I overlooking something obvious in the settings? (Ideally, it would be great if all "view" options could be memorised, so when opening the same segment later, all zoom options, and controller rulers could be restored.) This is very likely an oversight. I recommend opening a feature request on sourceforge: https://sourceforge.net/p/rosegarden/feature-requests/ - I wonder how the Figuration functionality actually works Not my area of expertise. Somebody here can probably fill in the blanks, though. Then we really should update the documentation based on what was found.

To get a closer look at what rg is doing to make those connections, load a composition, then go to Edit > Preferences... and press the "Details..." button next to "Sequencer Status".

But since the port number can change at each boot, or depending on the order in which the devices are turned on, maybe this is not a good method? I suspect that is what is really happening.

Re: [Rosegarden-user] Questions about audio playback and MIDI connections
Ted, Thanks a lot for your answer, here is the content of the Details window. In the Manage MIDI Devices window, the connections are not good. For example, the Roland XV-5050 device is connected to the 32:5 Motif-R MIDI 6 (write) output instead of the 24:0 XV-5050 MIDI 1 (duplex) output. And the MOTIF RACK device is connected to the 28:0 Unitor8 MIDI 1 (duplex) output instead of the 32:0 Motif-R MIDI 1 (duplex) output Regards.

So it looks like we need to more heavily weight the name portion and downplay the device/port numbers. Especially, it seems, the device numbers (24 in this case) which can maybe be completely ignored since they are completely unpredictable. This looks like it might be really easy to fix. I will have a closer look. Hopefully you can hang around for a couple of weeks and help me with the testing. I should be back to working on rg this weekend.
