Expert Pro CRC calculator for dp_cfg
#1
I've made a simple web-app to recalculate the CRC value in dp_cfg files if you want to manually edit your dp_cfg file.

Devialet Expert Pro CRC Calculator

Use it at your own risk. Be careful about simply editing the dp_cfg.txt file. It might be possible to damage your amplifier with a bad configuration of power levels, for example.

Wonderful effort, do you have the code source also available?

it's a simple javascript html page, so you can view the source code. you can also save the html file and run it locally.

Now if Devialet would only release documentation on all the parameters contained in those config files. I'd love to find a way to reconfigure my 440 Pro without having to depend upon the Devialet online configurator which has known issues with editing exisiting dual mono configs (e.g. 440 Pro).

I'm actually looking into that through the magic of AI coding lol. Most of the logic is actually client side, except for the SAM parameters which are generated from a server side API.
