Found a site that may interest you.....

....unless you've already discovered it.
 
Head over to reddit.com and look up the subreddit called bedroombands....
 
It is a place where musicians come to find others to collaborate with, basically like bandlab.  Super low key. 
 
Admittedly, I need to learn more about bandlab, and am not trying to steal you away from it, if you have already found a good thing.  Think there are 7000+ bedroombands subscribers now.... so it is growing (big may not be better).  Anyway, shouting out to you all because I know there is a ton of talent in this forum area (I have heard your stuff!) and bendroombands would do well to have your contribution. BTW: I am not affiliated at all with it (it costs nothing BTW), I am just a reddit user who found something cool, and am sharing here.
 
Wrote a tune and a guitarist from bedroombands helped me out.  Dude has skills. Check out the riff midway through.
