Hi Marcos,
  Thanks for reporting ¿recording MIDI in any track
works there on 1.7.0
 using this rg file? 
No, it causes an immediate crash. However I can record MIDI from vkeybd
into a new project OK, so perhaps there's a problem in your .rg file.
If it's no better with 1.7.1, I suggest taking the problem upstream.
   | Also, which drumkit did you have loaded in
  | Hydrogen? It sounds cool, anyway :-)
 The Colombo drumkit (my acoustic drum, sampled by myself)
 
ftp://ftp.ourproject.org/pub/musix/deb/musix-colombo-drumkit_1.0.deb
 All the samples (more than those into the drumkit), here:

Downloaded them, thanks!
