Instability in Rack

gioGramegna · January 7, 2021, 9:03am

Yeah, crashes happen from time to time. I have a pretty powerful laptop, still i get random droupouts sometimes.

I find it to be extremely stable… Honestly the Adobe apps I use crash more often than VCV.

From what I read in this forum, it’s a lot more common for modules to crash than for Rack itself to crash. If you care enough, you can mine the crash logs to find out who the culprit is.

It’s going to be a fact of life that not all plugins are going to be 100% reliable. You can control this quite a bit by using plugins that don’t crash.

I occasionally see crashes, or times when the user interface gets wonky, and I quit & restart. Luckily the autosave feature means you don’t lose work. I’ve never had it crash when I’m recording, it’s more when I’m screwing around building a patch.

gioGramegna · January 7, 2021, 9:47pm

Didn’t think of checking the crash log. Thanks!

I restart quite often while building patched. Was happy that I sorted out the hanging library (had to update drivers) and slowly learn what things not to do regarding my audio interface, but still the audio sometimes freezes.

Again, mostly during patch building, always related to me not using a module right.

Last crash happened now with this default patch :

maybe a problem in your system? - in my experience vcvrack is running very stable and such a simple patch should not trigger any crash i would say

Get the crash log!

Squinky · January 15, 2021, 6:03pm

I’m far from an expert on this, but it looks like someone is crashing trying to start up your audio device. Since it’s WSAPI, so you have an option to run some other kind of driver, like ASIO? Or perhaps someone who knows more about this stuff will chime in.

gioGramegna · January 15, 2021, 6:06pm

well, you are an expert in my book Anyway if i recall correctly, this also happens with ASIO. I use wasapi to record audio/video directly into OBS. Thanks for the interest btw.

LarsBjerregaard · January 16, 2021, 1:39pm

Agreed. I actually find this to be the biggest technical weaknes of Rack - the fact that plugins can crash the host (Rack).

LarsBjerregaard · January 16, 2021, 1:41pm

Yeah, bad audio hardware drivers (looking at you Windows) can crash stuff, and there’s a lot of bad drivers out there.

gioGramegna · January 16, 2021, 5:34pm

Mmh…i thought focusrite made some very stable drivers. Could also be an issue with latest updates of Win 10. Gonna investigate more…

LarsBjerregaard · January 16, 2021, 5:39pm

I’m on Mac (and the Scarlet interfaces are class-compliant) so no drivers installed, and I have no idea how good they are on Windows, sorry. This by the way, to me, is one of the major pluspoints for MacOS - you don’t need to install all those crappy drivers for totally vanilla/class-compliant hardware!

ldelimar046 · January 16, 2021, 5:42pm

Focusrite, eh. Man I thought that for MOTU as well, having 828x for two years And with recent switch from mac to windows im just disappointed, with so much cracks and glitches, random dropouts even at 88200 with 512 sample size. If you really want the stuff you have to pay for the proper stuff, its turbo that everything whats good is expensive but this is not the subject. I was looking at RME stuff and if you really want workflow to be super stable and superior than yes, the proper audio interface is a must. From rme, universal audio, and some other, probabbly there are plenty. Would love to know as well experiences

gioGramegna · January 16, 2021, 5:44pm

I actually own a recording studio and worked for years with a 24 channel setup with a saffire pro 40 on Firewire on Windows. Never had a single issue. Seems like the wind has changed for focusrite. Pretty disappointed with latest products quality especially software.

ldelimar046 · January 16, 2021, 5:46pm

Check RME Babyface Pro FS , its hottest thing on thr market atm, with decent pricing

gioGramegna · January 16, 2021, 5:50pm

i’m actually waiting for my ES-8 Will let you know how it goes. Hoping for the better.
