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?
