The Roland SH-101 was a great synth.  I have owned two of them personally.  They are a lot like the TB-303 with perhaps a little more ability for perfomance.  There were no presets available on this machine so any sound you wanted had to be created on the fly but what cool sounds it made.  In this soundfont I provide 7 sounds.  All are bass sounds except one sweep.  Click on the SH-101 to download the file.
