I came across this issue a few times. In a long session, after a while, DSP card is not reachable, although some of the effects are running. When I try to navigate there, I get the “DSP card initializing or not installed” (or sth like that) message.
Also a lot of glitches / artifacts when DSP is getting overloaded. I am not sure if there’s a fix for this at all, but worth mentioning in case you guys come up with something. The weird thing is in one session what does not overload the DSP card, can overload it after a restart.
I definitely had noise/artifacting when I first got the DSP card. It turned out some of the Airwindows plugins are pretty resource-intensive. I think a resource monitor would be helpful.
A resource monitor is a great idea and would really help to identify issues and prevent them from happening. I’m experiencing the same sometimes (after 4-5 hours use), but not using certain plugins or use them with care (like RX950) helps a lot.
@jeanvoyage I agree the DSP card needs some more love from the team and can be a challenge to work with, but it’s definitely not completely useless. There’s just a steep learning curve for everyone. After 6 months of use it really starts to boost my sound and productions. But finding a way was not easy.
i think the dsp card is great really. just needs polishing, improvements etc. its a pretty complex project, so i understand that many issues will arise with such an open system. but for me it’s already very valuable
Hmm. I regularly have mine running for a lot longer than that, but I’m also not adding and removing plugins the whole time. That being said, there are bugs they need to work through and it’s definitely siezed up on me here and there while removing a plugin, though I’ve never received the error message you did. As I’m thinking about it, every time that’s happened I’ve just restarted the machine. Maybe if I navigated to the DSP folder I would have received the same message.
I would file a support ticket if you haven’t already. Good luck!
I personally find the DSP card to be absolutely incredible and very well done, like everything with the S2400. Generally in DSP if you’re seeing dropouts or other behavior that might indicate things locking up as a function of time, it’s likely to be a denormal issue in the plugin - not an issue with the board. This can happen if you have something like a reverb tail decaying towards zero, the IEEE-754 floating point standard allows denormalized numbers to represent values very close to zero with extended precision which can absolutely choke a cpu (or dsp) if the developer hasn’t accounted for this with FTZ or some kind of dithering etc…. Obviously I can’t say for certain what is going on but this would be my first line of inquiry.
