BPB Cassette Drums is a Free Drum Machine VST/AU Plugin developed by Crimson Merry. This free VST plugin comes with a total collection of three drums and they are Cassette 606, Cassette 808, and Cassette 909.
Each of these three drum machines has its own user interface and you can also route the drums to individual outputs to process those sounds on your own.
This plugin is fairly good and if you are creative you can put this to some great use to create unique sounds.
