looking for a super basic drum sequncer

im looking for a very simple way to make a basic drum loop to listen to instead of a metronome/click track.

im using reaper/osx
id like the sequencer to be a vst(i) so it will sync to the changing tempo(s) set in reaper
just kick, snare, hi hat. sound quality is not really a concern


oh yeah.. looking for the free ones.
any suggestions?

happy new year!
