TR-505 Rhythm Composer

TR-505 Rhythm Composer © 1986 Roland.

It is a drum machine and MIDI sequencer from the same family as the Roland TR-909, TR-808, TR-707, and TR-606. The drum kit includes basic rock drum sounds similar to those of the TR-707, plus a complement of Latin-style drum sounds similar to those of the TR-727 (the Latin version of the TR-707).
