The CAT system is intended precisely to handle legacy software, so it's the right thing to be using in these situations. That will continue to be the case.
Regarding MIDI control, it's very unlikely that the F5K MIDI ports will *ever* be opened up directly to user apps -- MIDI access to the F5K is handled separately through the Virtual interface, so the issues raised here are moot. 73 Frank AB2KT On Tue, Jul 22, 2008 at 10:59 AM, Larry W8ER <[EMAIL PROTECTED]> wrote: > Jim ...
