Roland TR-505 Rhythm Composer
A cheap (budget) drum machine. It features 16 drum tones which unfortunately, are only mediocre samples. Its memory contains 48 patterns and 6 songs. Unlike its TR cousins it does not have individual drum tone outputs. There is no drum tone editing capability either. It does however feature extensive MIDI implementation, even the pads will transmit MIDI data. The 505 works well with a computer and sequencer or as a stand alone drum machine. It is extremely basic and unexciting but does make a good starter or play-along drum machine. Vince Clarke and Aphex Twin has used the 505.

LOTS of things can happen.all of them good.. if you ran out from the 505 to the MK you could control the speed of both from the drum machine. you could also write a note sequence ( though not super easily) on the drum machine and have it play the microkorg.. if you ran from the mk's out to the 505 in then you could "play" the drum sounds with the microkorg's keyboard.. i think that the mk sends midi clock so you could control the speed of the drum machine with the microkorg..
anyone used it with a Yamaha QY10 or Boss DS-330?
