I'd like to start doing some data acquisition/processing on the NeXT using  
digital ears.  I pretty much understand how to get samples into the DSP from  
the ears (thanks to Jean LaRouche's text/code), but am much more shaky on how  
to get into to the host, and onto disk.  I want to be as flexible as possible  
with the data transfer, as I hope to do a little processing of the data on the  
DSP before sending it to the host, and therefore the data will not necessarily  
look like a standard stream of sound.
    If someone could point me to some documentation or some VERY well  
documented code, I would be very grateful.

     - Orion

ps - what about the possibility of a unit generator that got data from the dig  
ears and passed it on so that other unit generators could modify it?  It seems  
that the main problem would be setting up the SSI interrupts.  Is this  
possible?
