Hi,

I encounter a problem while trying to control PD patch with midi.
I am very bad in math and I have no idea how to map 0 - 127 of midi value to -1 to 1 for my synth's pan.

In Max/Msp, or SC, I remember that they have an object called [map] or something.(in SC, .linlin method)
It usually takes four arguments, like (0, 127, -1, 1). then the object will automatically map first two arguments to second two arguments range.

Does PD has this kind of object?
Or I should do all in math? (combination of division, multiplying...etc.)

I wish that there's something...

thank you.

hello.

I'm using PD for controlling SuperCollider Synths via OSC and having trouble on how to format SC messages in PD format.

I encounter object like 'sprintf' and honestly do not understand very well.

I have some SC syntax like,

a = Synth(\dyn, [\freqs, Array.rand(8, 100, 200), \out,102])

and

error: sendOSC: no method for 'sprintf'
error: sendOSC: no method for '['freqs''
error: sendOSC: no method for 'Array.rand(8'
error: sendOSC: no method for 'float'
error: sendOSC: no method for '200)])'
sprintf's error: an object created without valid format patterns...
sprintf's error: an object created without valid format patterns...

Is there a comprehensive documentation on formatting messages in PD?
how they interpret things like "[" or commas and stuff.
I just need to make bunch of message boxes with SC command to send over PD's sendOSC object. it helps me not to type this things in SC but just click it in PD.
but I have no idea on how sendOSC will interpret strings and intergers, commas, semi-colones...etc.

'will be much appriciated.

thank you.

Hi,

it's been more than 2 years since I've tried PD last time. and yesterday I downloaded pd-extended again because I want to use PD to make control for the sound engines in Supercollider (using excellent OpenObject quark in SC).

For that purpose, I'm now looking for some inspirations. Many people told me that the best way to learn PD is by hacking/studying other people's patches. I am looking for,

everything about controlling:
-classical (step) or advanced (generative type) sequencer design.
-HID/MIDI control intergration to the GUI
-GUI design, innovative, classic, whatever...
-GEM patches that interact with control parameters and audio
-Arduino stuff
-OSC examples that uses OpenObject or others

basically, I welcome everything about control with PD, since I do everything related to sound/DSP in SC, I won't need "how to build synth" stuff...

My knowledge in PD is beginner's one. I barely understand what is "hot" and "cold" inlet. so, any beginner, tutorial type of stuff is also welcome.

thank you very much!

hi,

it seems that [enumerate( does not work on osx. (10.4.11)

is that possible to switch between multiple webcams without open dialogue box and
renew the gem screen?

thank you

**milc**

I've found this patch on the web to study purpose.
I think it's simple and small but the problem is I have no idea at all what is 'rms'??

If I can understand what it is, then it'll be much more clear...

thanks!!

Hi, advanced users!!

I'm trying to make a little sequencer using metro, counter, mod and [sel] object.
It's a copy of obiwannabe tutorial 001.

But since I sequence 3 instruments at the same time with a single toggle object to
on/off metros, I need to all 3 metros starts at the same value each time I stop and restart metros.
one metro is attached to counter and it starts everytime where it was stopped previously....

other two metros, no idea where it starts each time!!

It's very hard to sync them humanly.
Is there a way to start a counter and metro everytime from 0??

here's the part of my patch

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;

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

Hi, I'm totally newbie in PD/Gem.
I'm doing the included manual stuff, and I'm having fun just display images in Gem window.
The only problem is that, when I use [pix_image] and [pix_draw] objects,
it shows images upside down.

why this happens and how to solve this problem?
it will be awful if I have to fix this by using rotate object each time I load an image in Gem window.....

Hi,

I saw once in Max/Msp, people can export their patches in text format then re-import it in Max.

I'm pretty sure that in PD, we can do it too, but how?

For example, I have this copied from obiwannabe site;

#N canvas 0 0 401 227 10;
#X obj 17 69 metro 300;
#X obj 17 93 random 24;
#X obj 17 116 + 48;
#X floatatom 35 141 5 0 0 0 - - -;
#X obj 17 44 tgl 15 1 empty empty empty 0 -6 0 8 -262144 -1 -1 1 1
;
#X obj 17 165 osc~;
#X obj 17 198 dac~;
#X text 45 13 random note;
#X text 96 118 add 48 as lower limit;
#X text 96 70 a timebase generates bang messages;
#X text 96 142 random range is 48 to 71;
#X text 96 94 random number zero to 23;
#X connect 0 0 1 0;
#X connect 1 0 2 0;
#X connect 2 0 3 0;
#X connect 2 0 5 0;
#X connect 4 0 0 0;
#X connect 5 0 6 0;
#X connect 5 0 6 1;

then, how can I make it work in my PD?

thanks!

Hi,

when I render some 3d shapes, like boxes, cubes, or [textextruded],
I alwyas have this default shape in the center of gem window.
for example with [textextruded], I always have "gem" written in the center and I just can't remove or erase it...

any help??

thanks
