0.7 EXP version crashing on Mac in Ableton and Logic

[jacbou]

Plugin crashes Ableton and Logic
I had the previous version 0.6 installed before and that was working. Are there any old files or configuration files that I have to or can remove to start with a blank install to test this? (I deleted /Users/USER/Library/Application Support/modularsamples/Xolotl as well plus the VST3 and Component versions in their folders and did an install again, but still crashing.

Hmm, seems fine on logic here for the most part, not tested Ableton yet.

Generally speaking it's a good idea to remove old content with these things but it looks like you have that covered..

Are there any particular circumstances that lead up to the crash? Do you have the samples installed?

[jacbou]

No, nothing special. Quetzalcoatl and Oi Grandad work fine. It's an intel mac. I have Samples installed on an external HD, but it does not even select me where to look for the samples (crashes instantly). I now set the samplesfound to 0 in general config and restarted. It crashed but before created a LinkOSX file with a directoy name. I chnaged that to the real sample folder. Still crashes. Maybe just compile a new version or look at the compiler settings? I also tried the free version from github. also crashes.

[RickTaylor79]

This is bit of a head scratcher, the compile settings look fine & a quick debug didn't reveal anything problematic.

Some additional info might be helpful:

What's you OS Version?
Have you tried the vst3 version, does this also crash?
In the plugin manager; try running "Reset and Rescan" & post the results here.

Since you had the older version installed, clearing your plugin cache might help.

OS is MacOS latest version (15.1) on Intel. I' mainly using the VST3 version. I don't know how Ableton logs plugin actions, but could find this in Ardour's plugin scanner (shows the plugin as "error" after scnanning:

VST3 module-path '/Library/Audio/Plug-Ins/VST3/Xolotl.vst3/Contents/Info.plist'

Don't know, if this is of any help?

Just tried on my older MacBook with Big Sur. Same problem. Both had Xolotl 0.6 installed before.

[RickTaylor79]

Okay, that rules out my theory (if in doubt blame the new OS). Thanks for the crash report, between this a few other clues gives me something to work with..

The most significant difference between v0.7 and 0.6, Oi, Grandad! and Quetzalcoatl is that it uses FAUST for some of the DSP. I just don't understand why it works perfectly well for me (m3 air Sonoma), but not you on two separate machines.

I suppose the difference in architecture could something to do with it. The plugin is universal binary, though. I'm gonna fire up Sequoia in a VM, and see what happens.

Another quick question, in Logic does the plugin actually validate after a reset and rescan?

[RickTaylor79]

Okay, I've uploaded a potential fix, I can't guarantee it will work, please let me know how you get on with it. If it works I'll update the expanded version:

https://github.com/publicsamples/Xolotl/releases/download/0.7.0/Xolotl.Mac.Fix.zip

[jacbou]

This version does not crash and seems to work. I can't test it thoroughly though because I don't have the space for the samples on my old MacBook that I only have available until Thursday. Will give more comprehensive feedback when I'm back on Thursday.
ADD: Presets seem to work and it is producing sound, however on my older MacBook it is too resource-intensive to really test.

[jacbou]

Hi just tested also on the other MacBook. Works fine!

[jacbou]

Tested only VST3. In Logic this error occurs dureing validation:
PUBLISHED PARAMETER INFO:

# # 80 Global Scope Parameters:

[RickTaylor79]

Okay, thanks for the reports. I've posted fixed versions to both the release page here, and the expanded version over on Gumroad.
