hi, advanced users!

I couldn't get much help on vline~ help file.

What I want to do is to make long and dynamic amplitude control on
repetitive osc~ frequencies, so that the cycle of osc~ output becomes "musical" period.

But each time I try to put some list in the vline~,
it just doesn't work.

Can I make, at least, some kind of continuous vibrato effect with vline~?
or is there a better object for that?
any examples?

As you can notice, I'm extremely newbie in both DSP and PD world.

By the way, what does it mean "a time interval" and "initial delay" of vline~??

I'm sorry if I'm too stupid, but it's very hard to know alone....

please help me!!

here's my poor patch trying to make musical amplitude control....

#N canvas 748 414 454 304 10;
#X obj 64 175 osc~ 440;
#X obj 75 240 dac~;
#X obj 297 242 ezdac~;
#X obj 130 141 vline~;
#X obj 67 209 *~;
#X obj 140 45 metro 2000;
#X obj 142 11 tgl 15 0 empty empty empty 0 -6 0 10 -262144 -1 -1 0
1;
#X msg 137 74 1 1200 \, 0 230 800;
#X connect 0 0 4 0;
#X connect 3 0 4 1;
#X connect 4 0 1 0;
#X connect 4 0 1 1;
#X connect 5 0 7 0;
#X connect 6 0 5 0;
#X connect 7 0 3 0;

thank you very very much for any help!!!!

try this message to vline~:

"1 10, 0 100 20"

What this means is:

from whatever value you start at, ramp to 1 taking 10ms to do so, starting immediately, then after 20ms, ramp to 0 taking 100ms to do so.

If you do:

[metro 2000]
|
"1 1000, 0 1000 1000"
|
[vline~]

you'll get a 0.5Hz triangle wave.

thanks for the reply Claudius!

then if I type something like

"1 200, 0 1000 1000, 0.8 500, 0 900 400"

It can mean that

ramp 1 taking 200ms then after 1000ms, ramp to 0 taking 1000
then re-ramp to 0.8.....so on....

is it possible to continue the amplitude modulation like this?

I've tried but it sounded quite same as short list....

"1 200, 0 1000 1000, 0.8 500, 0 900 400"

this is not the correct way to use [vline~]

the 3rd number is the delay from the START of the first message.

so, you should make a message box like this:

[1 200, 0 1000 1200, 0.8 500 2200, 0 900 3000(

thanks hardoff!!!

your answer make everything clear and make my frustration disappear.
and save my ears too...(it made horrible feedback noise when I type wrong)
