Roland CR-78

The Roland CR-78 is an analog rhythm machine from the late 1970's.  It has 34 preset rhythm patterns, which can be combined for interesting results (ie: Rock 1 and Samba together).  You can vary the tempo, add fills, fade in/out,  mute drums you don't want, etc.  It even has an old school rhythm programmer, though I admit I have no idea how to use it yet.  Think Genesis, Phil Collins (In The Air Tonight), Hall & Oates, and countless others.  This box was a staple in the 70's before the TR-808 and TR-909 came on the scene.  You've heard it before.
