Sorry about the constant bombardment of questions that I throw at this
mailing list, but anyone got any clever ideas on implementing a gate?
It seems like a simple task, but I've tried a few things now, and I
keep finding some kind of snag.

Attached is my latest attempt. Because the loopseg opcodes are only
k-rate, I get noise during the rise and fall segments. I've also
attached the sample used.

what if you simply write a(kgate) as input for loscil?

in what way? I've tried using a squarish ftable to read a gate, but
the trouble is that when you change the frequency of the gate, the
rise and fall time of the amplitude changes aswell. I need one with a
steady rise and fall time, no matter what the frequency.

i meant, in your code:
asampl, asampr loscil a(kgate), icps, gifFCello00, 80

as you said you get zipper noise because kgate is not audio rate.  so i 
thought a(kgate) should interpolate.

New kick?

Sorry, you mean trick, I forgot that not everyone will see the full conversation. 

The trick is using a(kratevar) to allow me to use the loopseg opcodes to make a gate effect, because they only have krate output and were causing noise as is. I'll post the fixed csd tomorrow incase anyones interested

Sorry, I promised this a few days ago, here is the working gated
instrument. csd and sample attached.
