SampleScience are in a generous mood and have created a drum loop pack of a sampled Roland TR-505 drum machine which is free for everyone to download. We'd say that deserves a thank you at the least. Here's some more details from Pierre at SampleScience.
SampleScience TR-505 Drum Loops is a collection of 30 royalty-free drum loops made with the sounds of the classic Roland TR-505 drum machine. Each loop has been mastered to bring these sounds to life and make them exciting.
