It's good to see Modelonia resurrected – it's the most delightfully quirky synth that I know of.
However, my Live 9.2.1 on Mac OS 10.9.5 found this beta a bit too quirky, apparently – the Modelonia VST caused a sudden crash when I changed presets, after I'd explored for some fifteen minutes. Unfortunately, Live then disables the offending plug-in, so I can't continue testing.
Sorry to see that you are experiencing Modelonia crashes. I am just checking in during a brief interlude in my holidays, and have tried to reproduce this to no avail so far. I have two main test machines: an old MacBook Pro running 10.6.8 and an old but still grunty Mac Pro running 10.9.5. On the 10.9.5 I've just installed an Ableton Live Trial 9.1 (32-bit) I downloaded a while ago and had no problems with the AU. So to be sure we're testing the same thing I've just downloaded the Live 9.2.1 trial (64-bit this time, not sure if you are running 32-bit or 64-bit). I'm just trying the Modelonia VST now and still no problems.
I just tried the AU version (OS 10.9.5, Live 9.2.1 and Logic 10.1.1 on the same system): immediate crashes. I have the Apple crash logs for the enjoyment of your Mac programmer.
So, just to confirm. You initially tried the Modelonia VST and it worked OK for about 15 minutes and then crashed when changing presets? And after that it consistently crashes? What method did you use to change the preset immediately before the crash: the arrow buttons, the pop-up menu or the load dialog? Before the crash, did you change and save any presets?
Basically, from what Liqih has inferred from the crash logs, Modelonia is crashing during preset reading. This is the same preset reading code that obviously worked for you for the first 15 minutes (and is still working for me and hopefully other users; everyone else please send in details of hosts / OS versions that are successfully working too!) So my best guess at this stage is maybe the presets file have been corrupted somehow (which would be a bug we need to track down too, I'm not trying to shift the blame here).
If you are handy at the command line in OS X Terminal, could you please run the following command and email the resulting zip file to Liqih:
Code: Select all
zip -r ~/Documents/CrashingModeloniaPresets.zip ~/Library/Audio/Presets/Modelonia
Then, if you are feeling particularly brave, remove / trash that presets folder, either via the Finder or by running:
Code: Select all
rm -r ~/Library/Audio/Presets/Modelonia
The next time you rescan / open the Modelonia plugin (either kind) it should recreate that presets folder from factory defaults. If that works, then we can conclude that corrupted presets are a problem and we need to figure out what corrupted them. If that doesn't work, and Modelonia still crashes, then we need to investigate some more.
Is there anyone else trying out the Modelonia beta on a Mac? I'd like to get a feel for whether this is a common or a rare problem, since I don't have an obvious way to reproduce it myself here. Thanks for any assistance anyone can give.
