Improvising Drum & Bass Music on My Roland 505 Drum Machines

Just improvising with the Music. I have a broken Roland 505 that I cannot see on the screen. So I hook it up with the midi out to my other Drum machines and turn some to ch 10 for Drums. Ch 2 for bass Ch3 for keys, Ch 5 for whatever. That is how I figure it out and look at the red lights on the Drum machine. Lights 1 through I thinks 8. Hopefully, you enjoy the mix.
