[sdiy] USB to CV

[James Patchell]

         <sigh>....

         This is a subject I looked into a few years ago.  Of all the 
replies I saw on this subject so far, the person who suggested using the 
FTDI USB Comport IC and then using the Yamaha Midi->RS232 device driver 
probably wins the prize for the simplest and most effective way to solve 
this problem.  However, I am not in charge of handing out the prizes... 
:-), so until we find that person, you will have to just bask in the glow 
of knowing you won...

         I looked into writing a USB device driver.  And while it is not 
actually all that difficult, it was enough of a chore that I decided I had 
much better things to do with my time.  And, writing a Multimedia Device 
Driver is an even bigger mystery.  So far, I have not been able to locate 
in the Microsoft DDK the documentation on exactly how this is done...(well, 
it is almost impossible to find anything you want in the docs, so this is 
no big surprise).

         I downloaded the Yamaha device driver...now all I need to do is 
get an FTDI245B chip and do some experimenting.

         By the way, with USB...who cares about Midi2.0....the driver will 
send the data as fast as it can...which is pretty danged fast
