Alessandro Saccoia has released a free sample pack featuring the sounds of the TR-727 drum machine by Roland.
I have sampled some stuff before selling it. Here you find some clean samples of the tribal brother of the TR-707, the TR-727.
Note that the sample with maximum volume is the accented Hi Timbale, all the other samples’ volumes are relative to this one as it is in the original hardware. I haven’t normalized or changed the input gain across the samples, and I have left a couple of milliseconds of silence at the beginning of each sample, you’ll deal with in in your sampler.
