I forget where I originally downloaded this from, I got it some time in the 90’s. Though the 909 kit isn’t the most dynamic sounding kit out there, it’s often been a good starting point for many tunes that I’ve worked on. Here’s the message from the text file included in the pack:

Since it’s admittance into the world of music, the Roland TR-909 has been
one of the most sought after drum machines in existence.  Every dance,
techno, and hip-hop artist desperately searches for the “magic box”, only
to find the 909.  Yet, this box is highly coveted by those who worship its
demonic powers.  Many have tried to obtain this box through large sums of
money, deceit, and ultimately theft.

In order to curve the population’s insatiable thirst for the 909, I have
created a ‘complete’ 909 sample set. I’ll be surprised if you can tell the
difference.

For purists, this sample set will not totally replace a real 909.  The 909
sequencer is really natural for many dance and hip-hop artists.  But
in terms of sound quality, this set accurately reproduces the various
instrument settings on the 909.  In other words, it is the next best
thing to a real 909.  How many drum machines in the store have a five meg
909 sample set?

I hope you find this set useful.  Please feel free to copy or distribute
the set in any way.  Please DO NOT change samples, add samples,
delete samples, or modify this text file in any way.  Respect the work.
This sample set is FREE.  You may not distribute these samples for
profit!!   If you have any comments please feel free to email me.
Or, if you create a cool tune using the samples feel free to send me a
tape or dat.  Have fun!
