Hi,

I'm working on an Ableton Live controller patch in Pd. It will be used with an external graphic tablet from Wacom.

I'd like to use Pd to make "mutes" possible.
Normally i use a MIDI Keyboard and convert every Note Off message to an On message. So whenever i press a key the mute gets toggled to "off" and then when i release the mute gets toggled twice.

By now i am using "bang" objects. But they lack in the feature that they are just sending one bang message when they get pressed. I tried to something with "select" or "spigot" but these solutions aren't very good.

Does anybody know how to implement a button which sends two messages? (One when getting pressed, one when released)

Thanks in advance,
Zettt

Hi

I have some newbie questions about Pd. I wanted to write a Patch which is based on this one:
http://puredata.hurleur.com/sujet-643-sample-player
The mentioned Sample Player has 2 Sliders which control the Start-/End-Loop position which is the exact thing what i was looking for.

What i want to do?
I want to make a patch, a sample player. When i press a button i want to loop the actual sample position according to the key i have pressed.

I give you an example. I load a loop which is 120 BPM fast. I set somewhere my tempo. When i press "a" it starts looping 1/4th at the actual play position.

For this sort of thing. The Sample Player seems to be perfect. But now there are the difficulties.

How can i set the tempo right? I figured out how to calculate the tempo for any note length.
How can i get my keyboard entries into the software?
And lust but not least. How can i get the Patch to act how i would like.

I know...dumb question you know too. But maybe there is someone who knows one answer.

Many, many thanks.

Frank told me to make this tutorial to figure out

Thanks for his help.
If anybody has the same problem. Here is the message he wrote me:

Attached is a slightly different sampler, actually not a sampler
itself, but a tutorial on how to build your own sampler.

If you work through attached tutorial, maybe some of the neccessary
calculations (as: duration(smps) => duration(msec) etc.) become clearer.

Use the [keyname] or [key] objects.

Just build it! If you get stuck, try to make a patch that illustrates
where you got stuck and send it here.

You may want to start with empty subpatches, that divide your
problem/approach into smaller problems/steps. Like first do a
completely empty patch and put some empty subpatches in there:

[pd load_file]

[pd get_duration_in_msec]

[pd convert_duration_to_BPM]

[pd get_keypresses]

[pd play_sample]

or similar. Then give your subpatches inlets and outlets and connect
them in order. And last fill in these subpatches with the real patches
one by one, always checking if every subpatch does what it should do.

It's not a dumb question at all. While playing samples isn't exactly
magic, it's also not trivial to do, especially for the first time.

Fantastic!

Thanks.
