@LiamG @whale-av thank you both!

I do need a complex timeline, and my metro of interest can be stopped and restarted at any time. So i really need an "observer" or a reference timeline. Looks like there is no way around having a second metro.

Hi PD,

I'd like to plot metro's output using textfile object in a way that the result shows the bangs as 1's and all the other "output", if any, as 0's. This way I can visualize the temporal distribution of the bangs over a test period.

However, metro only outputs bangs on the "1"s and otherwise outputs nothing, so I can't figure out how to achieve my goal.

I wonder if there is a standard way of doing what I want.

Thanks!

Thank you very much for the detailed explanation.
I should've measured the signal output before posting.

Hi PD

I wonder if lop~ object's argument should be the filter's cut-off frequency.
I tested "lop~ 400" with an 1kHz OSC~ input, but then the signal sounds like there is no attenuation at all.
However, in Csound, such a test with lpf18 or biquad opcode (tuned to a one-pole) will attenuate the 1kHz sine accordingly.
So have I misunderstood the argument? I noticed that with lop~ and hip~, the argument in the help is referred to as "roll-off frequency" while their right inlets were termed "cut-off frequency". Are they different?

Please advise.

Hi,

I've used PD on Mac before,
now I'm running ubuntu linux 6.06(Dapper) on my amd64,
I followed the instruction and successfully installed
the pd-extension package, but when running it for the first time,
here is what I got:

pd: error while loading shared libraries: libjack-0.80.0.so.0: cannot open shared object file: No such file or directory

And i checked the libjack on my ubuntu is libjack0.100.0-0
and there is no 0.8 source for Dapper yet.

Any idea how to get around the problem without messing up my system??
Thank you.

Thx for the tips.

unfortunately it doesn't work

I got the same error saying:

pd: error while loading shared libraries: libjack-0.100.0.so.0: cannot open shared object file: No such file or directory

and I checked that the libjack file does exist under /usr/lib.

I'll wait to see the next release.
