Default reaper crashes with u-he "triple cheese"

salut,

I experienced a series of reaper crashes using u-he's wonderful "triple cheese" synth plugin (linux vst). I tried different jack-settings but nothing changed.

I post the message from the log:

Code:
Process 15411 (reaper) of user 1000 dumped core.

Stack trace of thread 15433:
#0  0x00007fd5ea1ee7a6 n/a (/home/udaemon/.u-he/TripleCheese/TripleCheese.64.so)
I don't know if it's due to my system settings (antergos/arch linux x64 w/ stock arch kernel 5.1.3 PREEMPT, i5-6300U CPU @ 2.40GHz × 4, 8GB ram, rtprio set to 98) or if the problem lies within reaper (or my almost-stock configuration of reaper) or with triple cheese.

any hints are very appreciated. thank you!

----------------------------------------------------------------------------
EDIT: I'm still experiencing crashes, but they don't solely occur when I use u-he-plugins, but also with different (linux native) vst-synths like wolpertinger or vex and furthermore they are dependant on the plugin's settings.

if any of you have questions concerning linux native u-he plugins you might find help in their official linux-forum https://www.kvraudio.com/forum/viewforum.php?f=292.

as for the mentioned reaper crashes I still don't know what to do except for avoiding certain plugin presets/settings and hoping it will not crash. the logs are not very helpful - at least to me.

maybe someone sees the problem having a look at the logs. therefor I post the usual messages of qjackctl concerning these crashes:

here, in the end it says there was a memory access error ("speicherzugriffsfehler"). everytime reaper crashes with a shorter or longer constant saw-tooth-noise.


are there further logs which I could check to get some more info?

thank you!

Default Autosave "when not recording"

I have the following configured:



Just now I've worked on tuning vocals with Melodyne, which I have running using LinVST. Sadly it crashed all of a sudden, so I wanted to restart Reaper and continue from the last autosave.

But despite those settings the last autosave was over 30 minutes ago.

Could it be that working within Melodyne is considered 'recording'?
If so, why?

Default scrolling faders and buttons

I don't know if this is a linux native reaper bug (or a bug at all) or has to do with the window manager one uses:

I figured out I can not scroll faders and button/knobs (with one exception!) with my mouse's scrolling wheel; I attach two images to illustrate what I mean.

this is not exhaustive since there are so many faders around that I can't collect all of them here.
remarkable is, I guess, that - so far - one knob can be adjusted mouse scrolling: the "wet"-setting of an fx as shown in the second image in the top right corner.

I'm using gnome 3.32 desktop under wayland.

can anbody confirm this?

Well, yes, that's the default behaviour (presumably to prevent accidental mousewheel changes) but it's not a bug.

Go to preferences (select Editing Behaviour-->Mouse) and uncheck "Ignore mousewheel on all faders" which seems to be checked by default.

Solves the issue here.

thanks, Xasman, that solves the issue here, too. I wasn't aware of this setting since I've never touched it.

Default Can't drag a pattern from MT PowerDrumKit

In Linux, I can't drag a pattern from MTPDK (as MIDI notes) to its track. It works perfectly on OS X.

When I drag and the point crosses the VST frame, the pointer changes to the drag icon with a "forbidden" sign on top (no entrance in red).

Linux platform - OpenSuse tumbleweed, Gnome, updated. I tried MTPDK using either Carla or LinVst.

That's because it is a Windows plugin running with Wine in Linux. When you use it in OS X it is actually running as a proper OS X plugin.

There is a workaround here:

I found a strange issue, which might be related to this:

https://forum.cockos.com/showpost.ph...&postcount=185

When I import a media item, duplicate it several times and press Undo (Ctrl+Z) all items disappear or get "minimized" respectively. Redo does not bring them back.

I'm on v5.978 at the moment, but the bug (?) also occurs in 5.91pre4.

I tried it with a default Reaper.ini file, but after some minutes the issue appears also.
It doesn't seem to be a general problem as it only affects some media items:

I cannot duplicate your issue. (MX Linux 18_3 based on Debian Stretch, XFCE, Compton enabled). I was testing this using a Dev version of 5.978 (I forget which one since I overwrote it today) and the latest 5.979rc2. I tried using the menu to copy/paste as well as undo/redo, and I also tried using ctrl+left click/drag (to copy/paste) as well as ctrl+z (for undo) and ctrl+shift+z (for redo). It works properly every time.

I also tried with items of different lengths (since your items seem short in length), and "show overlapping media in lanes" (such as in your view) and also not with that option. I still can't reproduce the issue no matter how many times I try.

I'm beginning to wonder if your system (your particular OS install?) has some issue.

Do you have any OS-specific keyboard shortcuts assigned to any of the command shortcuts you'd normally use in Reaper? You might have to check that.

Thanks for the comment. I tried to undo with the menu entry and I get the same bad behavior. I really can't believe it's a system issue, how can this be?

Are there any other files except of Reaper.ini that store some information? Maybe I should completely remove the .config folder and install Reaper from scratch.

There are a number of ini files in the Reaper resource folder (along with reaper.ini) which have stored information.

It couldn't hurt to try a fresh install. I'd back up all the files (full backup of everything in the Reaper resource folder), try the fresh install, and if the problem is solved then maybe overwrite one ini file at a time to see when the problem comes back.

Damn... I did a fresh install and after some minutes it occurs again.
edit: I booted into a MXLinux stick install and there it's working.

Maybe this helps. I did some more tests and this is reproducible:
I can do undo until I load a plugin (tested with Repro-1 and Hive from U-he). After loading the plugin it's not working anymore.

This does not happen on the Live MXLinux install and it seems to be specific to my system.

Can you reproduce with any non-U-he plugins?

No luck by me reproducing, but I only tried Reaper VSTs...

I tested now many other plugins (inlcuding TripleCheese and Podolski), none made any problem. After loading Repro-1 (or Hive or DIVA) the bug was there again. Do some more tests.

edit: Ok, it's for sure the U-he plugins that I bought. And this also explains why I never ran into this as I just bought them this year.

edit2: This is the terminal output when loading Repro-1

Code:
Fontconfig error: failed reading config file
Fontconfig error: failed reading config file
Fontconfig error: failed reading config file

The problem is solved. At least it´ s working at the moment. It was related to the decimal separator. I set everything to en_US.utf8 on my system now. Before it was German. I also had a comma sometimes in the REAPER.ini file as decimal separator next to point which likely caused the issue.

Default Memory leak?

Reaper 5.978
Linux Mint, 17.3 64 bit
Cinnamon or Mate desktops
CPU: AMD Phenom II X2 (yes, a little long in the tooth)
RAM: 16 GB
Graphics Card: NVIDIA GeForce 210 (fanless/silent)
Boot Disc: Samsung SSD 860 EVO 500GB (boot drive)
Other storage: 3 Western Digital RED 2 TB Hard disks (RAID 5)

Memory leak?
Leaving Reaper running (with project saved and no track armed for recording) for a couple of hours (had situation that need to be urgently dealt with) when I came back the application was extremely sluggish, to the point of being unusable. Even quitting reaper was a problem, leaving unresponsive blank windows on the screen. Nothing else was running except the file manager so I restarted X-Windows (Ctrl+Alt+Backspace (but you need to re-enable this as newer distros have it disabled for "safety" reasons)). Restarted Reaper to resume work, and everything ran like clockwork, for awhile. When it starts to become sluggish, save your work, kill Reaper, restart, and away you go for another couple of hours (depending on your project size).

Menus won't stay up.
Occasionally when clicking on the drop-down menu bar, the menu drops down then vanishes, never giving the user a chance to make a selection. If in the middle of a project this can be rather disconcerting, bt you can save your project. Click on the close gadget and Reaper will ask you if you want to save the project, say YES. Then restart Reaper and all should be well again. Not a huge bug, but it should never happen. Perhaps related to the memory leak?

CPU: AMD Phenom II X2 (yes, a little long in the tooth)
RAM: 16 GB

Boot Disc: Samsung SSD 860 EVO 500GB (boot drive)
Other storage: 3 Western Digital RED 2 TB Hard disks (RAID 5)

Memory leak?
Leaving Reaper running (with project saved and no track armed for recording) for a couple of hours (had situation that need to be urgently dealt with) when I came back the application was extremely sluggish, to the point of being unusable. Even quitting reaper was a problem, leaving unresponsive blank windows on the screen. Nothing else was running except the file manager so I restarted X-Windows (Ctrl+Alt+Backspace (but you need to re-enable this as newer distros have it disabled for "safety" reasons)). Restarted Reaper to resume work, and everything ran like clockwork, for awhile. When it starts to become sluggish, save your work, kill Reaper, restart, and away you go for another couple of hours (depending on your project size).

Menus won't stay up.
Occasionally when clicking on the drop-down menu bar, the menu drops down then vanishes, never giving the user a chance to make a selection. If in the middle of a project this can be rather disconcerting, bt you can save your project. Click on the close gadget and Reaper will ask you if you want to save the project, say YES. Then restart Reaper and all should be well again. Not a huge bug, but it should never happen. Perhaps related to the memory leak?
I guess there are and haven't been any plugins in the project.

Default OSC actions in linux Reaper

I don't know if this is universal, so i'll start here as if its a linux only bug.

I've managed to get OSC working in Reaper, controlled from a tablet running Touchosc. And i've managed to assign a couple of keystrokes enabling me to select next/previous tracks.

The problem is the actions jump a track. In the osc midi monitor, it shows why. When the keystroke actions is pressed, it sends a signal value of 1.000000.
When the key is released it sends another signal value of 0.000000.

This is interpreted by Reaper/osc/something as 2 keystrokes, not one, so i go from Track 1 to track 3 to track 5 and so on.

Is this a Reaper bug, or an osc issue?

And if someone is using touchosc with the reaper templates, with linux Reaper, are you having the same problem?

Alex.

Default Insert bank/program select event

I'm trying to add a Program Change in the correct lane (bank/program select) with the action "Insert bank/program select event" and nothing happens.

Anyone else have any success with this?

Alex.

For VSTs? Where is "Insert bank/program select event" located?

Default Default project settings media path doesn't persist

Can someone verify?

To reproduce:

Open a project
File > Project settings > Media tab
Enter relative path under "Path to save media files", like Audio
Click "Save as default project settings"
File > New project tab
File > Project settings > Media tab
"Path to save media files" is blank

It works fine here (the path in the default project setting persists) when following your exact steps, and also trying various other variants such as saving/closing, starting new project etc.

Default Custom font choice affects CPU use?

(I also posted this in the v5.979+dev0619 pre-release thread in case it affects more than Reaper for Linux. Here, it might get more Linux users' awareness and input.)

Here's a little something that caught me off guard. It seems the choice of font for the menus (in Reaper for Linux) can affect the CPU.

I had edited the libSwell.colortheme file on my system while using MX Linux (using XFCE desktop environment), changing the font to Noto Sans (and making the font sizes a bit larger). It seemed to work fine. Noto Sans fonts are included in MX Linux, a significant number of them.

Now I'm using Linux Mint (XFCE). By default it also has the Noto Sans font family (including additional variants). I imported all my previous Reaper settings (since it was a SSD format / new OS install) so when I started Reaper it was using that same libSwell.colortheme file. However it seemed the menus were sluggish. Opening the "options" menu for instance (since it's a long menu, good for this test) and moving the mouse cursor up/down, the highlighted menu option lagged behind the cursor significantly. Also my CPU spiked (I could hear the fan spinning up).

When I (finally) tried a font other than Noto Sans (Open Sans for instance) in the libSwell.colortheme file, the menu responsiveness returned to normal and the CPU didn't spike nearly as high (probably a normal amount under the circumstances).

I could guess that using certain fonts in a theme might also increase CPU and make things more sluggish. (So I switched all my custom fonts to Open Sans just in case.)

I don't know why in Linux Mint XFCE this would be any different (same DE, using the same window manager/appearance/DPI/etc. settings as MX Linux since I'd made notes of all of it and set it up exactly the same in Mint as I'd done in MX), except for the fact I notice there are lots more Noto Sans family font variants installed (it seems there are ~2x the number as MX Linux, which is kind of insane). Perhaps if the font chosen in Reaper is part of a very large installed font family, it has something to do with it? (Just a blind stab in the dark.)

It's not a huge deal since there are lots of fonts a person can use. But this might help narrow down some of the "sluggish UI" complaints happening especially with MacOS.

If you want me to test something further, let me know. I don't plan to switch distros again for a while, but other than that I'm open to suggestions.
