Actually, I did not include all of the information.
So far I have been using Screen Monkey for more than 12 clips by using the page up and page down features. This actually lets me randomly access a fair number of clips, really just limited by how many page up and page down commands I want to put into the show control software. We are using SFX and it lets you do strings of arbitrary MIDI commands. So if I need 36 clips, I put two page downs at the start of each clip, then the appropriate number of page ups. This works fairly well, though it is a bit heavy. The ability to call up random clips by having the velocity specify the clip number sounds like it would work very well! (addendum: As I look over the ETC website, it appears we can upgrade the software on our console and have it send cue numbers via MIDI. If it does that, they will be sent as program changes, with the program change number being the cue number. Would that be doable? If it were, we and anyone else who wanted to use this could hook an ETC light board right to Screen Monkey and put video cues right in the cue list. Very cool!)
In this show it sounds like we will be using Midi Show Control from the light board to run the video clips. The light board (an ETC Express) only spits out 'Go!' commands, so the random access really won't matter in this case. With the new spreadsheet cue view I think it will work perfectly this time around.
So I suppose this has really become a 'please add a command to randomly access cues, if you have a chance' request. Adding MSC seems very specialized and not likely to be helpful for many people, unless other users also want to be able to hook cue lists to their light boards. Even then it really is just basic 'Go!' functionality, coming via a SYSEX message.
