[LAU] sample license

Hi all some time ago i sampled a vintage rhythmbox (the Denon CRB 90) and created a hydrogen drumkit with these samples being the good civilian i am i decided to try and contact Denon and politely ask them if i could use these samples (and if possible release the drumkit under some sort of CC license) the answer i got was this : uhu : nada, nothing, null, etc ... so i figured if they dont allow me to use the samples ... why dont you guys ;-P no seriously, does anyone know if i can use the samples -without going to jail and all- the box is really old (see http://crb90.files.wordpress.com/2010/08/rhythmbox-crb-90-japan-advert.jpg) so i was wondering if there is a limitation on the time that samples are 'protected' by a license any ideas ? thanx guys! grtz Thijs -- follow me on my Audio & Linux blog <http://audio-and-linux.blogspot.com/> !
