I don't know if you can load patches via midi BUT....
 this won't solve your "tape hiss" problem in any case. The OB-8 is
 not a sampler, loading patches is more like turning the knobs and then
 hitting the save button. If you have a "hiss" you might have a problem
 with the "noise" being on or there may be some problem with the final
 amp output, or likely it is just the nature of the old analog beast.
 Use a noise gate if it is hissing when you are not hitting any keys.
