How do you make a led on a custom page come one with a logic statement? I am using a trigger meter to change a preset and want notification if this has happened.

It sounds like you're looking for an indication that you're in a particular preset which as we all know can't be done because a preset is an event, not a state.... right?

Well, as an alternative, how about using a Counter Trigger.
By default, one rising edge trigger on the input (ie from your meter trigger) and the output will stay High.

You'll have to think about some way to clear / reset this at some point otherwse it'll stay High forever.....

That was just an example. Maybe this is a better one. I have a logic device monitor tied to the falt on an itech and I want a graphic on a custom control panel to change if the amp goes into fault.

[Logic Object]-->[Logic End]

Drag the Logic End's default control panel graphic (the panel you see when you double click on the logic end) onto your LED or graphic indicator on your custom control panel (or drag it from the design tree if that's more familiar to you).

lots of things that "can't be done" in soundweb, can, in fact, be done (yes Dan, I can learn :) ).

If you need an indication of whether a preset has triggered, you can simply add a logic source to the parameter preset, and store whichever states you desire with the source on. If you have four presets, and four logic sources, you could indicate any of the four presets, if that's important.

Venue presets would be the same, just create logic sources in whatever state you want, and you'll have an indication of whether you are in that state or not. It might be a bit harder with a venue preset, because you'll have to remember to create the right sources for each preset. Using serial triggers and a loopback serial connector as Dan describes in his response to using a pushbutton and rotary selector to control gain, might work here too. (It would work above, but is far more complicated than necessary, and unless you WANT needless complexity, why bother? Plus it could slow your logic responses down slightly (although honestly... count to 200ms)

If what you need is an indicator that the preset *has* triggered at some point in the past (ie, you want to trigger a "fault" light/message on your panel) us a latch, as you describe. then you'll have a positive indication that an error occurred, even if it is not currently occurring. Add a button linked to a logic source linked to the reset port on the latch, and you can clear the error flag. Hide the button, or use a region button to make an invisible area of the control panel clickable, and you might be able to tell if someone has been abusing your system while you weren't around.

If all you need is an indicator that the fault is happening now, nitrogen's solution will work very well.

If your "custom control panel" happens to live on a crestron or similar controller, then none of that applies, and you'll need to send appropriately formatted serial data. (or better, subscribe to the logic end). But that's a topic probably best left alone, unless you have a LOT of time to devote to it, or a competent crestron programmer available.

As with most things SoundWeb, there's more than one way to skin a cat.

I tried the solution of dragging and dropping the logic end onto the LED, but all I get is "The data currently on the clipboard cannot be pasted here".

What am I doing wrong?

I'm trying to make it so I could possibly trigger a furman sequencer to turn on/off by the Blu-10

find the logic end in the design tree, expand it and drag the 'SV' onto the LED.

Or find the logic end in the device window, open it then drag the indicator on to the LED

You cannot select the logic end in the device window and copy it to the LED, it has to be the indicator (i.e. the SV)of the logic end.

I know it's bad form to post a reply to yourself, but for those who might be following this topic:

It turns out that Bounce was attempting a turn on a physical LED, not a custom control panel LED. With that little detail established, it wasn't difficult to walk him into the correct answer.

I just thought some of you might be interested in knowing!
