Re: lfo synced to midi

2006-03-03 by coyoteous

MIDI has been obsolete for more than a decade, but is so implanted that it will probably be 
here long after we are gone. Remember MIDI2 or ZIPI? MLAN is/was also supposed to be a 
MIDI killer. What we need is a fast standardized duplex protocol for event information and 
high resolution continuous control. Home brew "ghost electronics" + MIDI are about as 
close as it gets or may ever get. I'd still like to see a USB 2.0 or (IEEE1394/Firewire) to (and 
from) CV module. But why limit to sub-sonics? Some cheap audio interfaces pass DC on 
one end and/or the other, but as Paul S. has pointed out in the past, the resolution in the 
sub-sonic range is probably inadequate for precise 1V/oct pitch control. Planetarium laser 
show controllers have used modified ADATs and sound cards to accomplish a flavor of this 
for a long time. I would think there would be some off-the-shelf industrial controller 
technology that would do the job, but in my limited searching I haven't come up with 
anything.
