I figure out a simple method:

first use pack~ and then divide the list (signal vector) with list split. After that use sum divided by list length and you have the total energy of grouped bins (coming from an fft)

Is there any object/method that groups and adds together samples from a signal-vector?

I found out that pack~ object zexy library do exactly that...

I want to create control signals of the energy for every bin in an FFT analysis with control rate of 1/(blocksize/samplerate). Any idea how to do that?

Is it something build in to handle control messages exactly how delwrite~ and vd~ handle audio signals? Or I have to build it from scratch with arrays and counters...

Has anyone used a phasor~ to a vd~ for looping? Any suggestions how to avoid clicks in the jump of the phasor~? Maybe a second vd~ in order to fill the gap only at the jump point?

I am working on a project with live video and I reaching my cpu limits only with 3-4 gem chains. Has someone managed to optimize gem performance (Intel IPP, multiprocessor, pd~)?. It would be really helpful to assign different gem chains to different processors, which will render to the same gem window.

I am trying to generate some commands, in order to be used in a sequencer. The [metro] object generates the values and with the

Finally I managed to create a record and resize module without clicks but I am not sure if this would work with my live-system which includes many buffers, record and player modules...

I noticed that all weird behavior (clicks after resize, clicks by recording in a previous resized array) comes from the tabread4~ object. Without getting any message, this object generates the clicks when the array is resized (and not only!). Does someone know why this is happening?

Is there a GUI object for writing lists and have internal send and receive objects?

I am using abstraction and dynamic patching to create and load multiple samples from instrument sounds. So for example my abstraction [instrument_samples Violin], with the argument Violin read from the folder Violin all sounds, creates the corresponding tables (with the proper names 1_buf_Violin, 2_buf_Violin ...) and load the sounds into them. It is working correctly and I am using this abstraction to load 11 different instrument sounds. The problem is that when I open the main patch, it is supposed to load all of them, but I get the error :

warning: 1-buf_Violin: multiply defined
warning: 2-buf_Violin: multiply defined
warning: 3-buf_Violin: multiply defined
...

It is very weird because the abstraction for all the instruments is the same and it is working well. Earlier I was getting this error for the Flute...
I cannot understand the behavior of Pd. I used a random object with a delay in order to load every instrument at different times but the same problem insists. The total size of samples is 100 Mb and my ram is 2 Gb. Any ideas why Pd behaves so weird?

Is it possible? I need dynamically record from different microphones into different buffers.

I have stored a sequence of bpm's numbers in a text file and I am retrieving them with the textfile object with delta time. The problem is I want to have a number box which shows the actual time relative to bpm's. Although the timing with the text file is accurate (it changes with every bpm) the time indicator have a problem. When for the del object (see example) the time has come to receive a new bpm, it sends first a bang and then receives it causing problem in synchronization...
I can't find a way to force the del object to wait for the new bpm...
Any ideas?

Is there an object which returns the size of a folder. I want to automatically create buffers and put there all the sounds from a folder.

I want to play sounds from a folder with readsf~.
How can I make it read from the folder it is in, in order to be able to play it in other computers with different paths?

For example /Users/.../samples/Piano_Samples/$1-Stein.wav works fine but only in my computers.

../samples/Piano_Samples/$1-Stein.wav
or
/samples/Piano_Samples/$1-Stein.wav
or
samples/Piano_Samples/$1-Stein.wav

doesn't seem to work.
Any ideas?

I have a number box with send-symbol and receive-symbol messages specified. Is there a way of routing the send messages that comes from receive messages and the ones given by mouse (clicking the box and scrolling up and down)?
I really need this!
Or alternatively is there a way of avoiding internal loops (two number boxes with the send and receive-symbols reversed)?
Thanks in advance!

Has anyone manage to get an USB Steering Wheel working in PD? I have a Logitech, which PD (hid object) doesn't seem to see it...

Is it possible to access the argument of an object inside the object? For example I make the object:

|pd test arg-1|

and inside the pd test-1 object I want to access the arg-1 argument in order to pass it to a message. I tried this:

|bang|
|
|
|$1|
|
|
|print|

but I get 0 from this. Any ideas?

I have connected two different usb gamepad and through the hid object I am receiving the number-values from the controllers. The problem is that the left analogstick sends values wich correspond to the right analogstick (of the same gamepad), so what I make with the left stick influences the right (actual only in the x axis). This happens to both gamepads witch make me wonder if they are so built. When I press print in the hid object I get:

As you can see that there are two Z-Axis, witch make me wonder. Is there a way to separate the values of the two analogsticks (of the same gamepad)?

Has anyone experience connecting >=2 (actually I want 4) usb gamepads and controlling them separately and totally independently with one computer? I am planing to make a interactive installation and it would be nice to know before I buy them. Also does anybody know about the USB cable length issues? Would it work with 5 meter cable?

Thanks in advance
