probably an easy way to make an USB->midi converter would be to start
with one of these.
http://www.ajusd.org/~edward/ezproto/
http://ezusb2131.sourceforge.net/
you probably wouldn't need anything more than the cypres chip and some
optoisolators to make a nice NxM port USB midi bay. plus, you can make
the driver actually follow the usbmidi spec so it will work under linux
automagically
(http://member.nifty.ne.jp/Breeze/softwares/unix/usbmidi-e.html)
btw. has anyone verified that the midiman doesn't follow this spec? if
so it should just work by adding its id to the list of supported devices
by the driver.
on another note does anyone know if this works under linux?

I am guessing yes, since it is a straight usb device and yamaha is
usually good about standards but a data point would be nice.
