Hello there, Stephen here

I am working on a project. PD is my chosen backbone. I need to control the volume or automate the volume of the frequency.pd example in the pd browser. For example I want the volume to rise from 0-midpoint, hold for a minute and then reduce to 0 again. Its simple I know, I'm sure, I mean I can imagine how simple it could be... It took me a long time to get to grips with HTML and even now its more familiarity than understanding that gets things done. I've attempted to get familiar with PD several times and this time I'm getting warm..

Perhaps someone could suggest (diagrams are best for my mind) a solution!

Kind regards and a grand thank you in advance of your efforts..

heres to heating up pd- a warm fire for dummies somewhere near the centre of things.

Hi Stephen,

You can use the [line] or [vline~] object to automate volume changes.

The [line] object doesn't cue up commands, so you'll have to use delays to sequence the automation.

[vline~] is an audio-rate object, is sample-accurate and can cue up commands.

Have a look at the difference in the attached patch.

Hope that helps.

Thank you very kindly indeed.

I attached my efforts to date (perhaps for amusement) - though since following your suggestion things have cleared up a great deal.

Most helpful.

May I ask what you're trying to achieve exactly?

plate tuning, maybe ?

Hi again,

I am sending frequencies via small speakers to metal plates. so i am attempting to make a patch that will send different signals each on its own dedicated channel at the same time. From a laptop output via toslink to an amp with several speakers attached with varied volume and timings.

thanks for your responses
