Safe to use the power strip for turning off/on all my gear simultaneously?

[flocked]

I have a lot of music devices which need to be turned on manually for each jam session. I’m wondering if it’s possible to just use the power strip to turn all instruments simultaneously on and off… I’m too lazy to use the power switch on each instrument each time…
Can anything happen or am I save in doing it? I have some Elektron boxes, tt-303, as-1, etc… Or is there maybe any particular gear where you should use it’s internal power switch?

Is it dangerous? [switching off power strip at wall]

I wonder if it is dangerous to let machines's power switches On and then use the general switch on my power strip to turn them all at once. Does it make any difference? Are the AC-DC adapters actually working before we switch a machine On? Aren't the AC-DC adapters good enough to stabilise the possible peaks that could occur when switching On the power strip's general switch? What do you think?

Thanks.
Sorry. Used the search but somehow couldn’t find anything.
