Trigger button from multiple input universes

[daedeloth]

Hi,

We are organising digital quizzes at public venues where both quizmaster and players use tablets/phones to play the quiz. In the past I have setup a module that controls the venue lights based on the quiz events through the qlcplus web api (http://www.qlcplus.org/forum/viewtopic.php?f=29&t=11875), but to make the whole system a little more generic I'm trying to switch to MIDI to control the lightning.

Since Chrome has an excellent MiDi interface, I was able to setup a proof of concept fairly easily; I've managed to trigger midi messages from chrome without much issue and I do receive them in qlcplus. Example available at http://regie.catlab.eu/midi.html, I'm sending midi messages through channel 1. At least in linux it's easy to get it working, I just use "port-0".

Now the actual issue: I also have an AKAI apc mini that I use to take control in case the game doesn't has any demands (for example, during the break, I want to be able to manually trigger the scenes, or when the game crashes I also want to be able to take over manually).

However, it seems impossible to assign two "triggers" to one button. What would be the proper way to be able to trigger the same button from two midi devices?

Thanks!
Thijs

install 2 help buttons both using a cue with a loopback channel.
Then bind that loopback channel to your main button.
Solved
(only problem is when both inputs are active ... there is no priority or so - or you put both helper buttons in a solo frame or you use an inhibit button which forces a '0' value to the loopback channel (LTP))
