I've come up empty on that search, too. I thought about adding a songwriting/production section here, since a number of us have more pop than orchestral backgrounds. I haven't done it, though, since there's such a high risk it could dilute the orchestral emphasis the forum currently has, which we definitely don't want to lose. Plus if the section got popular, we'd have to be careful to keep things from devolving into Garage Band tips or a pile of "Check out my SoundCloud songs!" spam. It would require a lot of monitoring.
Here's a thought, though - After the holidays, when things slow down, I could start a songwriting/ pop production section here. Just current members, though, who know the difference between a violin and a viola, so the sophistication level stays high.
Then, if/when we get to a point where the pop side starts to dilute the orchestral side, we spin off the pop side into a separate forum, which would have the advantage of a built-in group of engaged people. Engaged sophisticated people.
Hmmm, as I typed that out, I kinda like this idea, since I think there are a bunch of us who lean more songwriter than composer. I'm open to thoughts, though, since obviously we don't want to screw up what we already have. Or maybe there is already a community out there we don't know about.
