I know that 3.2.x software doesn't work with the DP2000 but does anyone know if it will work with the old network LTC / midi box that looks like a DP 2000?
Yes current builds of Hog-3 software work with the old IOP (Input Output Processor).
I'm told the upcoming Hog-4 software will no longer support the IOP. The replacement solution is to hook up a MIDI/SMPTE widget to the USB port on the back of a remote DP-8000 if a netowrk LTC solution is needed. Also Hog4 will be able to support up to 8 simultaneous timecode sources.
