Hello @Relaxnow,

I’ve taken the liberty of formatting your code nicely. (FYI, you can do this by wrapping code with a line before and after that both have three backticks ``` on them).

Regarding the crashing, details of the issue and several solutions can be found in the in-app tutorial in chapter 6.2, ‘FX in practice’ (also online at Sonic Pi - Tutorial). Have a read and try one of those - let us know if you have any further questions :slightly_smiling_face:

With_fx outside live_loop’s seems to have fixed the issue. I can run all code without crashing.
Kind regards

Just wondering: Do “with_fx” run when all the samples are uncommented with # inside?

I mean. Do I need to use / / around on a code section that are not active to be on the safe side?

As I understand it, yes, fx will run regardless of whether any sounds inside them are commented out or not.
As to whether this can still become a performance problem, perhaps, but I’d appreciate @samaaron’s confirmation on that :slight_smile: Just like when you have active sounds within the fx block, I’m sure it depends on the amount of time in each cycle of the enclosing live_loop. If there are enough sleeps of the right duration in the live_loop to allow a single fx instance to complete before the next one is triggered for example, then there shouldn’t really be any need to comment anything out I’d say.
