Goldbaby Productions has been producing free sample libraries of tape and cassette samples of classic Roland instruments (recorded on analog before being sampled again you get a nice, warm sound out of the results.).
- a TR606 recorded to an Ampex 1/2 inch 2-track tape machine;
- a 808 samples set recorded to a portable Marantz deck.
