Graincloud patch error

[cmodica]

hi every body.

I use a lot the Graincloud FX that i found in the Usine Patches Library.
But, each time i use this patch, when i quit Usine i have a message to tell me that Usine closed unexpectedly.

If i close the workspace, open an empty wp and Quit Usine. It is OK.

Today i have an error message about this patch when i open the WP.

Usine 6.0.251117 / Macbook Pro M4 Pro / Mac OS 26.5
It is the same problem whith Usine 7.

Thank you.

Hi !
The problem comes from the preset system (a script) that is in the subpatch on the left hand side.

This is what I recommend :
- replace the preset system with a Json and global array string system (that will allow to use presets on various instances of grain FX)
- also, I'm not a fan of the granumlator, as it is very CPU intensive, use grain cloud sampler in circular buffer mode instead.

Thank you.
I am not an expert but i will try.
What is a Json ?

[oli_lab]

Hi !

Json is a string that contains data and name of datas.

check the addons in HH7, I put an example.
Don't forget to upload the "data_lab_7" version 7.1

I install HH7 Beta, but my HH6 Licence is invalid with this version. So impossible to download some addons to test.
I try with HH6 but impossible to find Json in the DataLab.

the HH7 beta licence is available on the download page, once loaded in HH7 Beta, you'll be able to use the addons.

with HH7 use only the "7" olilab addons.
