[sdiy] USB to CV

[Gabriel Lindeborg]

Haven´t our mother told you that plug'n'play is dirty word? ;-)

I think you will have to teach Cubase, or any other computer based 
sequencer, how to send CV as well...as I think they use DC blocking and 
normalization in software.

The ready made out of the box MIDI over USB drivers included w. both 
OSX, WinXP and Linux is probably the way to go.

And I think one can get the MIDI over USB standard to talk in fullspeed 
(12Mb/s), or more than the standard 32K anyway, which makes MIDI lagging 
less of a problem.
