"This Auction is for a rare Korg kpr-77 drum machine
It was originaly sold at around the same time as the Roland TR-606. In alot of ways its very similar to the TR-606 ITs pretty much exactly the same size , has the same number of sounds Kick,Snare,Open hat,Closed hat,Cymbal/Clap,Low tom and High Tom. It has two trigger outs that are 1/4 inch outs as aposed to the little ones on the 606. It also has Dyn Sync so could be synced to a tr-606 or tb-303 etc but i think korgs sync 48 ppqn.
I have owned a few 606s in the past and much prefer the sound of the kpr-77 the Toms are awsome the kick isnt as tight as the 606 but sits nicely next to the toms the hats are really nice metalic sounding and the clap is hipnotic."
