My friend owns a Gold edition copy of Horizon with a 512-channel interface. One of the things I'd like to do with it is get it to send MIDI show control to another computer to trigger sound cues. I know how to use MIDI the real difficulty is this. Horizon is designed to do this, however it is only designed to do this (or so they tell me) with one of two external modules that have optional MIDI interfaces. These are the Horizon Playback controller and the Horizon Ethernet Node. We don't have either of these, and they are also discontinued (as is all of Horizon as I'm sure you know). Anyways my friend who owns it wanted me to see if there was indeed a way we could still get it to work. I don't have the programming skills needed to patch Horizon (and yes it's the GOLD licence so that is possible under the licence). We are currently using cheap USB MIDI interfaces. And it does work, just Horizon doesn't talk to the MIDI interface. Any ideas that don't require large sums of money?
