Is this possible to create a command in Pd which may change the colour of the patch's window or turn off the screen of the computer automatically?

I've made a chronometer for performance of my piece and in the end of it I'd like to turn off all lights in the concert hall (also a computer's display).

Thanks for all your help.

Stupid question.

I would like to use two microphones as an input in pd patch. So, should I set 'multiple devices' in audio settings, and how to differentiate several inputs? Make arguments in [adc~]s?

Thanks for all help.

Is there possibility to make a command in PD which opens file using another software? I mean for example the patch with bang/open command which opens the picture file or PDF file (and the application opening such files, of course).

How could I store only one number from a stream of numbers? I mean the situation as follows:

...
|
[random 10]
|
|3\ (next is 4, 7, 2... etc)
|
[ ] what should be in this place?
|
|3\

And what may I do to store only one from next numbers (so only the second, only the third... etc)?

Is this possible to open a file from the disk by the command [openpanel] but without an "open file" browser appearance, so directly?

For example: is it possible to open the graphic file using [image] connected with [openpanel] (or maybe something different?) without necessity of choosing the file from list given in "open file" browser? (According to this, the file could be open when the patch is running- using [loadbang]).

Is possible to make the patch which make long sound based on short sound playing on piano (to make modifications of timbre and colour of lenghtened sound)? I mean for example the situation like this:

keystroke - this part of sound is elongated - end of sound

Thanks for all help.

Hi. I have problem with command [select]. I use it this way:

|10 50000(
|
[line]
|
|10\ (number)
|

[r number]
|
[sel 3 5 10]
| | |
| | | | |x|

Numbers are changing from 0 to 10 (0, 0.01, 0.02, 0.03 etc...). But it doesn't work as in example above, because [select] doesn't mark toggles. Where is the problem?

How could I amplify different partials of inlet signal from [adc~]?

How to make a random-like tool to generate numbers from set like [1, 4, 7, 10, 15, ...] not from sequence [1-1000]?

How could I round the value in PD, especially stream of values (like in number box showing pitch in [fiddle~] object) to have only the integer?
