You are here - Hydrogen to drumkv1 drumkit conversion tool

I just wrote a conversion script that allows drumkv1 to use Hydrogen drumkits. I thought some of you might find it useful :)

You can find it here:

The two samplers have a lot of different features and not everything translates well, but most parameters will work just fine.
I figured out all the conversion scales (pitch, panning, and so on), but I might have missed something so please let me know if you see any ways this script could be improved.



I downloaded the Then extracted the py file to /home/user/bin (what is part of my PATH) and chmod'ed the file to make it executable.
As stated in the help file I then executed the following command: /usr/share/hydrogen/data/drumkits/Techno-1/ /home/user/drumkv1/test/

but nothing happens. No output, not even an error message. And no new file(s) in the destination folder. I also tried it with several other drumkits that came with hydrogen.
Is there something that I am missing? I have python installed.

The file formats in the drumkit dirs of hydrogen differ from flac over wav to aiff. I tried it all, but to no avail.
Does the conversion tool expect any special file format or some sort of compressed file?

Can anyone help?

Ok, I got it. The converter expects files ending with .h2drumkit
