Script FX Issue

[DanH]

Some of my users are experiencing crashes in Ableton and I think the issue is the Script FX module I'm using. I adapted it from the Master branch and had to replace some nodes like the delays, and make a new modchain. I haven't compiled it to a .dll because none of my exported plugins open if they have a .dll inside them, so have just rolled with the Script FX as is.

Is there anything obviously wrong here? I can't replicate the issue here by the way. It was fine on Master....

I would guess your issue is cause by the send/receive nodes, in my experience, they have to be treated gently :D . Try setting their max value to 0.5 instead of 1 to avoid feedback loop, which will cause audio crashes.

[Matt_SF]

@DanH let me clarify what I said :

I don't know if the user can change the node's feedback value, but if they do, try to limit the 'overall' feedback value to 1 (0.99 would be safer).

If not, the issue may still be related to the FB but would depend on the intensity of the incoming signal. (not sure, just a thought but I encountered several issues with the send/receive nodes).

[DanH]

@matt_sf thanks, will check them out. There's no user control over any of it.

Appreciate the help :)

[DanH]

@Matt_SF you were bang on with the send / receive nodes. I (think) I managed to re-create my issue with an fx plugin in ableton. Without the send / receives all is ok, but with them it's a fairly straightforward crash.

[Matt_SF]

@DanH I noticed if you're using only one set of send nodes (e.g. for a simple delay) you shouldn't worry, but if you plan to use multiple receive/send nodes, you need to keep these under a certain value.
Experiment with your script fx by using high values for (all) your feedback parameters and see when the audio crashes in HISE. Then you'll know which 'max' values you should set.

[DanH]

@Matt_SF Thanks, I tried to set max values like you suggested before, which were either 0.3 or 0.12, and it wasn't having it

I tried with only one set as well, but no joy.

I have tried with setting the values to full as well, but HISE doesn't crash. Only in the plugin does it do that. I can live without them for now, the change in sound is super subtle...

Try pushing the audio input level into your fx to see if something happens...
