I’m using for drum tracks Poise (http://www.anothersmallclue.com). Podium didn’t find the multiple out so I achieve create manual ones. Now it works fine, but it shows a weird warning sign. Should I ignore it? or have I to do something?
I have never set up a multiple out, so it is not a direct answer to your question.
I’m afraid that the “Red !” symbol kind of means that something is wrong with your setup and you will have to fix it .
Have you had a look at the Wiki at all. There are some very good tutorials by Podianer (a little old now, but still useful). Take a look at the one I have given a link to below. It may help.
Other than that, it may be a problem with the plugin itself…
