Following the success of their Roland TR-626 HD sample pack, SampleScience
is proud to present RX-21 HD, a high definition sample pack of the
Yamaha RX-21 drum machine:

The RX-21 is a mid-eighties entry level drum machine featuring one drum
kit that can also be found on other Yamaha drum machine models (among
them, the Yamaha RX-11 which has been used by Aphex Twin on his latest
album and also on his previous double album “Drukqs”.

Included in the pack are the clean recordings of the RX-21 drum sounds
in 16 bit, 24 bit and 32 bit 44.1kHz wav file format. As a bonus, the developer
also added tube processed  samples with 4 round robins and a cool 80s
reverb version of the RX-21 drum kit.”
