hi, thx for the quick response
seem that when i record the screen the UHD Graphic do the work and GPU VEGA very little efforts.
The fact is that the AMD GPU doing the work when using vidéo softs
and i use vidéo sample in this project in the less cpu usage possible.

in the vidéo ( meesssy but it's testing " ) )___you can see and here that the CPU over usage and the poor participation of the AMD VEGA....GPU

Hi folks =) i have no clue why but my pd only use cpu to render video... i can't find how to use my GPU with GEM...
fact it's worst than that becasue i got the vtdecoderxpcservice problem that's sucking my Cpu ( https://macsecurity.net/view/553-vtdecoderxpcservice-high-cpu-mac) ... so it's a kind of double topic..!)
Does any body could help?
thx+

sorry ...with some tips it's easier

hello every body, found this some where i can't remember, it was from a granular patch probably ... ... it works really great BUT would be even greater if there would be a third point of control on the envelope. Here in the patch we only have Bias and Shape. i juste can't make the math in pd hann, pd curved and so one, so i 'm asking for help.
Can't find many example working in this way to generate envelope, did u ?
thx for your time ++
falta_sustain.pd

..with the technic from the "really usefull tuto.....meanly my probs are : i can't modify the hanning specifications (to read env shape from a array) working on each grain separetly.
nor dynamically changing number of instances in the clone object.
...any ideas ?

coming back with some exemples soon

THANKS
this is super clean ")) precise pitch.
I'm succefully working with this patch :

more easy to connect and synchronise with a gem video player but less "rich" than yours.
I did try to modify your patch to fit to my plan but i can't get the video results i have with the clone object way. i also have pitch issues and over CPU use.. what do u think ?)

@weightless hey it's seems to be great but I " store.param $0 sustain" is missing
...
still got it some where?
thx
