Renoise Crash: GUI Thread Exception (in combination with some Renoise Scripting Tools)

[j105f]

Renoise 3.4.4, Windows 10 64-bit.

I have been getting frequent crashes with both Redux and Renoise in the past year or two. Usually they just close instantly without any error messages in the GUI or log file, but this one provided an error message and crash backup file.

It occurred as I pressed Ctrl+S to save the project. I took a screenshot to show the state of Renoise when the crash happened. SPAN was the only VST loaded and its GUI was not open.

Here is the log file:

Here is a link to the crash backup XRNS:

PS: A crash that I reported previously has some similarities to this one. They both have a GUI Exception and this crash also involves note-off layers (used in instrument 00):

Sampler note-off layer crash

In the “Samples” area of the Sampler (with the “Samples” area in focus/selected): Renoise crashes when I attempt to paste samples into a “note-off layer” or “note-on layer”. [layer_Crash] This is the error: A fatal error or crash occurred (unhandled exception in thread: GUI). System specs: Renoise 3.2.1 (64-bit) Windows 10 (64-bit)

Thanks for reporting. This seems to happen in combination with one of your installed Renoise Tools - still is a Renoise bug though as scripts never should be able to crash down Renoise.

To ease replicating this, could you send me a zip of all your locally installed tools via a private message or email?

C:\Users\XXX\AppData\Roaming\Renoise\V3.4.4\Scripts\Tools

That would help narrowing down the problem a lot here as I can’t see which version of the tools you have installed.

[j105f]

Thanks for the fast response!

Tools ZIP sent via private message.

Also, I should probably mention:

In my Scripting Terminal and Editor, the TestPad.lua had the exact conents of com.Fornicelli.AssignAllMIDIInputs.xrnx → main.lua.

I disabled all of my tools and the crash still occurred when I saved a song (no error message; Renoise just closed abruptly as the song was saving). So I opened the same project and tried saving again and Renoise crashed again.

With all my tools disabled, I wondered if there might be some stuff in TestPad.lua causing it. So I deleted the contents of TestPad.lua and then the project saved successfully with no crashes.

Maybe just a coincidence but probably worth mentioning, since TestPad.lua wasn’t included the Tools folder that I sent.

[taktik]

The content of the Testpad.lua file is not evaluated, unless you run it in the scripting editor.

Could not replicate the crash so far. Maybe it’s the song which somehow got corrupt? Or do you have this problem with other songs too?

[esaruoho]

hi, what’s “Assign All MIDI Inputs” do? do you have a link to it?

[j105f]

I do get frequent crashes in Renoise, though unlike this specific case, there usually aren’t any error messages or any indication of a crash in the log file; Renoise will just close immediately without warning.

The crashes seem similar to the behavior of my Redux crashes, where I haven’t noticed any specific action that causes them. They have occurred when saving songs, loading songs, editing samples… though I do have auto backups set to be saved every 5 minutes, so it could be occurring as a result of the autobackups being saved…

I’ve enabled auto backup saving and manually saving my songs frequently, so I haven’t lost much work because of it… I’ve adapted, haha

[j105f]

That’s a simple tool I made to assign the MIDI Input settings of Instruments 00-0F to MIDI channels 1-16 of a chosen device. I’ll attach it the .XRNX this post. I don’t intend on developing it any further or releasing it… twas just a quick tool I wrote for personal use.

Not saying your crashes have the same origins, but it could be hardware issue related. A while back I had a lot of issues with renoise and my computer and it turned out one of my computer fans didn’t work causing the computer to heat up, crashing whenever a cpu taxing renoise song was playing back. Perhaps think outside of the box?

[j105f]

Yes, I think a hardware problem is possible, since the crashes started happening around the time that I bought a new computer a couple of years ago. Before that Renoise was stable for the ~6-7 years that I had been using it. Though I don’t notice any crashes/unexpected behavior in any other software.

I have a theory that it could be related to a tool that I was using (LiveDive) that hasn’t been updated in years. I would have to constantly disable and re-enable it in the tool browser for it to work properly and maybe it somehow corrupted my Renoise installation? Idk, just an idea since taktik said it seemed to be related to a tool.

Yesterday I uninstalled and reinstalled Renoise (also deleting all Renoise-related folders in appdata/roaming) and I didn’t migrate any of my previous settings, so essentially like a clean “factory reset” I think. For now, the only tool I have installed is SamRender, since that is all I need for the stuff that I’m currently working on. So maybe this new installation might fix the issue. I was able to work for an hour or two yesterday with no problems. =)

[taktik]

Could be another problem. The song you saved here the last time it crashed: Does it always crash? If it does, would you mind sharing it with me?

[j105f]

No, the song I posted didn’t crash consistently. I was able to load the song from the crash backup and continue working on it without it crashing. Sometimes I’ll remember the everything I did to a song before the crash happens. So I’ll open the song again, repeat the same actions, and Renoise wont crash. So I haven’t found a reliable way to reproduce the problem.

So I got another crash with my new installation today (not the GUI exception; the more frequent case where Renoise simply closes without an error message). It occurred while attempting to save a song. I typed in the name of the xrns in the file browser save dialog and hit the save button, then my entire screen got blurry for a second and Renoise closed.

Here are the Error details from the Windows Event Viewer:

Faulting application name: Renoise.exe, version: 3.4.4.0, time stamp: 0x663a057a

And I looked through my Windows Event Logs at all the entries for Renoise errors, and here is another with a different exception code & fault offest:

I have quite a few error events from Renoise in my logs and all of the Error events for Renoise have the same exception codes and fault offsets as those 2 events.

The exception codes are the same for my Redux crashes, posted in this thread:

Frequent Redux crashes in REAPER

Hello: I have been getting frequent crashes while using Redux in REAPER for many months now. I’m not able to reproduce it, as I don’t notice any specific action that causes it. IIRC, it has occurred while loading instruments, editing samples, and while not directly interacting with the Redux GUI at all. Below are the details of 2 Windows Event errors that occurred when REAPER/Redux crashed. This first error occurred immediately after loading an XRNI and playing a note or two: Faulting appli…

i see. i’m wondering if you wouldn’t mind some suggestions for improvements - because it seems this does not allow for assigning other midi inputs from 10 onwards to 1F for instance, since it’s hardwired to do 00-0F

and if there’s only 3 instruments, then it only sets instrument01-03 instead of creating the 00-0F slots that are missing to cover all midichannels for selected midi device

and also instrument.name is not (nondestructively) modified to show which channel is assigned etc.

added this anyway:

Hello, I’m having a similar issue in macOS trying to run the Demo, I couldn’t succesfully run it. I have this error and no log path to provide:

When I try to reopen, there’s a waring about Cardinal VST that couldn’t be loaded, so perhaps that is the conflicting VST.

[aprilix (Aventi α,β,γ,δ,ζ,σ,ω)]

I seen in the package that there is VST2 and VST3

maybe one work better than another
