Yeah, for what everyone's talking about Back In Time is, in my opinion, the solution.
I just need to decided whether to update to the latest stable from the special PPA… maybe skip it since everything works perfect already run as root… I love Back In Time

Strange. Did you change something in the previous session that caused it to not boot? It doesn't make sense that it would just "stop booting" all of a sudden.

Very strange. I had installed a new version of the Mindo backup software, and maybe I let a few upgrades happen. Actually, it would boot, but not load the desktop, and error messages were about gsonf-sanity-check-2. Google shows results going back three years. Oh well, it is a complex operating system --- and its free, so I won't grumble too much. (and Mindo still doesn't work!)

Better not further hijack the KXStudio FAQ thread further off course than the very valid topic of needing backups.

Ok. Is PianoTeq a pay-plugin? I see a spalsh screen indicating that it's a demo with only 20 minutes of use available..

Yes, it's a commercial plugin+standalone that gets installed with 'kxstudio-meta-non-free' package.

I actually have PRO license for it, their devs were super cool to provide me one after my work for juce-lv2

Nice perk!

It's certainly a nice enough instrument to tempt one to purchase it... Hmm..

I always close everything, including the Midi controller, before stopping JackCtl. But sometimes I get this error anyways. Sometimes it stops fine. Other times, not.

Should I close in a different way?

nope, this is a known bug in JACK itself.
I think it's fixed in the latest git code (upcoming v1.9.9), but I'm not sure.

just ignore the error if possible

Ok.

I'm learning to use Klaudia, which I like better than having to open things separately. In fact, in Klaudia, I can run Hexter and record in Audacity, as I prefer. But when I use Hexter in Carla, Audacity doesn't see it.
Strange..

But I'm liking Klaudia, so I don't mind!

Opening LMMS in Klaudia, and activating an instrument (in this case, "Organic") I get the following error:

Code: Select all

Could not write file /recover.mmp. You probably are not permitted to write to this file.
Please make sure you have write-access to the file and try again.

Was I supposed to change a permission somewhere? Or am I using LMMS wrong?

this is a lmms bug, regarding auto-save feature (default project defaults to /recover.mmp, which is not writable).
just save a project somewhere and this will go away

Ok, thanks..

Now, playing with Synth1 on FeSTige (the one with almost 10,000 presets

) I am experiencing crashes when certain presets are selected.
So, I opened FeSTige in the terminal to see what it gave. Here's what happens at the crash:

otherwise the crash doesn't tell me anything, and there's nothing I can do.
and trying to debug a wine application is hell...

this is why we should not rely on Windows software under Linux. when stuff like this happens it's hard, or sometimes impossible, to fix it.
you'll just have to learn what is safe to do or not (ie, which presets can be used).

Oh. Ok. I didn't know if it was FeSTige, or Wine, or Synth1 that was causing the problem.

I don't know if the source code is available; I do know that there are many people who put out their VST instruments for others to download. All the ones I have are free, so I suppose there is some type of "sharing" between the developments. But I don't know if it's something that can be changed easily.

In the update today there was a /etc/lsb_release file that could be kept or upgraded. I kept it. What's the difference? Would it have changed any settings?

Ok, a quick question about RAM usage:

I start by opening QJack, then the instrument I want to play, and then Audacity. After I make a track, I close the instrument, open another, make a new track, etc. At the end, I close everything, QJack last.

Sometimes I run "top" in the terminal to see what's using what, etc. I see that at the start of the session, I'm using little RAM. But by the end of the session, I'm using all my RAM, even after everything is closed.

Should I re-log-in in order to free up the RAM? Or reboot? (At the moment, I have only Firefox and QJack open, but RAm usage is almost 4GB!)

Thanks!

Unless some application is consuming that much RAM, this is a known linux feature afaik.
The memory used by applications is not completely free'd, as there's no need for it. It will be re-used later in case you start the same apps as before, thus making it start faster.
When you get out of memory, the older unused one will be used.

I think this is correct, although I'm not 100% sure. Still, it kinda works like this.

I see.
Yes, in fact, I upped my RAM from 2Gb to 4Gb, but I think 2Gb is probably sufficient for recording/playing, especially since I prefer to close things once I finish using them.

Thanks falkTX.

Someone on gearsluts.com was asking if I had tried OpenOctave. I see from the website openoctave.org that the repository has been created. Can I go ahead and add it?
