Circuit Bent Tr-505

The Roland Tr-505 was the trailer trash cousin of the famed Tr-x0x line. Unlike the other Tr models, the 505 was built for budget musicians. Even the individual outs were missing, and one could not edit the samples. The memory held a paltry 48 patterns and six songs. It did, however, get a decently useful midi implementation and some tiny attractive drum pads. For those reasons, it is a machine ripe for circuit bending. The above video shows just what happens when you start wrenching the guts of this easily had and otherwise forgettable little box.
