(008) Pure Data - making a simple oscilloscope utility

This video shows how to make a simple oscilloscope utility that it reusable in any other patch. It's useful for visualizing waveforms and for troubleshooting and debugging. I'm sure it could be improved upon but I wanted to keep it simple and easy.

[@CarlColglazier]

This was very helpful, thanks!

[@MichaelRohaly]

Thanks! Stole this. Now I have to figure out a way to make it settle on the zero points instead of travelling. Some sort of pitch sensing and consequent correction maybe?

[@Darqoni]

Thanks for the tutorial!
however I build it following along your steps and I keep getting the error message "bad arguments for message 'resize' to object 'array' " ... How to fix this?

[@natozlo]

done everything exactly as demonstrated but doing oscope~ in a new patch does not do anything and isnt recognised, any tips?

[@amberdoniere1884]

Thanks for your help. once creating a new patch, I'm unable to get the array into it (what happens after 4:25). Any advice?

[@pd_7773]

Did you select "graph on parent"? See 3:55

[@amberdoniere1884]

@@pd_7773 yes, i can try again though

[@boironalexandre2861]

thanks for the video, it helps me learning basis. However i'm not able to do curved connection as you did... I think that's why it doesn't work (when i'm connecting [osc~400] to [oscope~] nothing happen..) thanks if you could help me !

[@Shertigan]

Had the same problem, I don't think it's about the curved nodes (probably just an aesthetic change from purr data, the pd version used in the video).
Double checking everything solved the problem for me, I had wrong settings in the toggle object properties. (that checkbox should be crossed and must have an "init" parameter selected)

[@garljoens]

well I'm not sure what happened but mine does not work like yours does

[@d3nt391]

For some reason I don't have resize as an object. Any ideas?

[@pd_7773]

Are you using Vanilla PD? I'm using PurrData in this video. Maybe it's only a PurrData feature.

[@loops03]

Resize isn't an object, it's in a message box

[@adamschumaker]

total newbie here... how did you get the red box to grab the array and slider? What was the moves you did there?

[@pd_7773]

That's what is happening at 3:55. Right click in a blank area, choose properties, and turn on "graph on parent". Depending on what version you are using you may need to move and resize it by entering the numbers manually. I'm using PurrData here and it allows dragging and resizing. Hope this helps.

[@adamschumaker]

@@pd_7773 yeah what's weird is the red box appears but I cannot move it, resize it, or anything. I'm using pd 0.51-1

[@pd_7773]

You probably need to enter the location and size manually in the properties dialog.

[@meditationabode8505]

@@pd_7773 hi~bro!!! what is the version of Puredata you using allows resize graph-on-parent? That's so cool!!! was it by virtue of certain plug-ins? Thx~

[@pd_7773]

@@meditationabode8505 It must just be a default setting/ability built into PurrData. I was using Pd-l2ork v2.14.1.

GRANULAR?

[@pd_7773]

There's a little FM in the middle and AM at the end but no granular in this video. I've played around with granular synthesis and it's a lot of fun but all my patches get unruly and hard to reuse or share.
