The path to & from each M/E allows for up to 4 DME feeds from one keyer, but a maximum of two individual paths. That's why you can't send Key 2 to the other DME channels...you have already used up the maximum number of paths from the M/E by putting 2 DME's onto one keyer. Whether the crosspoint holds will work for you depend on whether your DME channels are set up as internal or as external. If they are set up as external, then you should be able to activate crosspoint holds at the DME level or at the AUX bus level. If the DME's are internal, then the crosspoint holds need to happen at the M/E level, as it is the M/E that is doing the feed, not an AUX bus which is what happens when using external channels. When you are saving effects, you'll want to save M/E 2's timeline (or snapshot) as well as each channel of DME's timeline (or snapshot). Recalling just M/E 2 will set up the M/E & feed the key bus to the DME's, but the DME's won't recall their position unless their effect is also recalled. Thus, if M/E 2 is on effect #11 to do your effect & DME's 1 & 2 are on effect #12 to set up the double boxes, then you can recall each of these elements separately & combine them into a Master Effect by highlighting each level in the recall keypad area, then pressing MASTER, then pressing STORE, and then entering any number from 1-99 (I'll say #3). Now, highlighting Master & recalling #3 will call up M/E 2 #11, DME 1 #12, and DME 2 #12. The same holds true with snapshots - if both M/E 2 & the DME's have been set up with snapshots, you can use the same procedure to store a Master snapshot which will recall dissimilar register numbers for different levels. If the M/E is stored as a Snapshot & the DME's are stored as Effects (or vice-versa), then you need to use the Shotbox to store and recall dissimilar effect types of different registers. But if you're running an effect on M/E 2 & your DME inputs are changing, it sounds like your DME's are internal & you should apply your XPT HOLDS at the M/E level.

Thanks for answer. I understand first part of your answer. I was doing that. I can assign up to 4 DME's to one keyer. That is what i did. I have assigned DME1 and DME2 to KEY1. Than I wanted to assign DME3 to KEY2 but it is not working. That would easily solve my problem. But I think DVS9000 can not do that. So I need this thing. When I change keyframe DME sources are changing. I do that by choosing XPT hold for DME effect. Question is if there is any way I can do the same thing with another keys and or with Tbar. Its like every keyframe I change DME sources I "recall snapshot" and my for example KEY2 is gona change according to keyframe I am at. Maybe you have answered this in the second part but I am not sure what to do :) Sorry to bother you I am going to ask another question. When I am adding keyframe switcher can remember sources for DME's at each keyframe by pressing XPT hold in Path setting for DME effect. But there is also M/E2... option and KEY options inside M/E2 with XPT hold button. Does this option doing the same thing? Ie. remembering its source (KEY1 to KEY4 or whole M/E2) like snapshoot recalling at each keyframe? When I save keyframe on keypad I can save it for DME1 to DME4 or as a master or just for M/E2 etc. Does it mean when I save keyframe for all DME's and for M/E2. THen I can remember state of M/E2 and change it with keyframes? Thank you bob.

To assign more than one DME to a keyer, try the following: Assign your keyer in the Keyer Panel. Activate a DME (such as DME 1) & its button will turn green - this, I assume, is what you have been doing. Now activate another DME...that's all there is to it. You can assign up to 4 DME's to one keyer. But if you're going add a DME, make sure it's one that's in sequence to the one that you first chose. For instance, if you started with DME 1, then choose DME 2 - not DME 3 or 4. You will have to build & store separate keyframe or snapshots for each DME, and then use those registers with your M/E register...either as a shotbox recall or as a Master Effect or Master Snapshot. That should do for you what you're trying to accomplish.

...My english is not as good as I want it to be Sorry for that :)
