Hello All,
apologies for this really stupid question but it's my daily curiosity ...
If i have a csd that doesn't use k-rate variables can i use a low value
for k-rate (i.e. 1) without influencing the resulting performance?

I guess that k-rate has some influence but am i right?
How k-rate influence the compilation apart for k-rate variables?

Thanks,
ciao,
francesco.

krate does not juts affect k variables.  a varaiables are vectors on ksmps
and various opcodes only update internal parameters once per k cycle.  A
k-rate of 1 woul dmean the audio vectors would be 44100 (say) samples
long.  It does depend on the opcodes you are using.  Also notes star/end
quantised to the  kcycle, so you could only have events starting/finishing
on a second boundary -- may be what you want....

It will affect timing of events. As these happen at k-rate boundaries, and latency too.

Yes, thanks, beautiful!
I have a little arpeggio (6 notes in 2 sec) and just discovered
that with kr=sr i will have 2 chords.

For a low level users like me Csound is a daily surprise also due to my low
memory ...

PS: i had a previously message about k-rate and audio in, where audio in
quality is influenced by k-rate (only with ksmps=1 i have good audio);
i guess is for same reasons You explained, right?

Thank You,
ciao,
francesco.

It will definitely slow down with ksmps of 1. I find that performance is good with ksmps of about 15 our more.

Still, ksmps of 1 will probably sound better because envelopes and cutoffs will be more precise.
