DSP card gets incredibly noisy when it hits a plug-in threshold

I was working on a beat and noticed that when I add had four plugins going at once (not all on the same bus), I started hearing some noise. When I added a fifth, it start a horrible amount of scratchy noise. I tried different combinations of plugins to see if anything seemed to be the culprit, but I nothing jumped out. Once I got down to three (any combination), everything sounded fine.

I decided to I see if this was project-specific, so I loaded up another one. This time I started hearing noise on the second plugin, with the third getting super noisy. I went back to the first project, and that behaved the same as before.

I have my audio coming out of the eight individual jacks, and each one has noise when soloed. The headphone jack also has the noise, and lowering the volumes in the DSP Mixer didn’t have any effect.

Has anyone else experienced this?

EDIT: I struggled getting the short ribbon cable off during installation, though I got everything seated properly. Could I have damaged it and caused this issue?

I have just experienced this. Yes using airwaves “galactic” reverb. I deleted all effects (clear, under dsp menu) and the crackling disappeared. When I hit play on the project there was no sound and when I saved and re-started the 2400 my dry project had no crackling..

It turns out that a lot of the Airwaves stuff is poorly optimized and thus incredibly resource-intensive. Isla is planning on optimizing them for the S2400. In the meantime, I’ve been relying on plugins from other sources.

Hi, i got the same issue on my DSP Card, using like 5 or 6 plugins from airwindows make my DSP buffer crash.

No fix to this issue 1 year later?

Yeah, I have the same issue. I am a huge s2400 zealot and pump up the device everywhere I go - but the DSP card is apparently a multi-core, separate CPU - yet, I can load maybe 6-7 plugins before the machine becomes totally unusable? It’s not running any applications, no GUI, it’s just processing DSP. So why such a limitation? Everyone says “Airwindows plugins are CPU intensive” - really? 6 plugins is too much to handle? That seems ridiculous - it’s an entire dedicated computer to running a few algos.

IDK, It’s honestly the thing that bothers me most about my S2400 - it’s far too unstable to use for any sort of live performance and is largely the reason I am seriously considering selling mine. I regret buying the DSP card

”Airwaves stuff is poorly optimized and thus incredibly resource-intensive. Isla is planning on optimizing them for the S2400.”

Hope they get to this soon.

Yeah, i just try the same plugin on my Mac and they are absolutly not CPU intensive i use 2 Xfilters the cpu dont go more that the 1% you get when you start the DAW.

I will like to know if we can Factory Restore the DSP Card uninstall the old version of the LV2 Airwindowsand install the lastest.

I think this issue is about a bad optimization of the plugins and the CPU can handle way more plugins.
