http://thounds.com/ is a place where you can post musical thoughts or compositions, and others can play over and mix with your composition.
I really like the idea of this, so I joined just to have some collaborative fun, and see how this cool little idea works.
After trying one recording, here's what I found out.
You will have to have an external mic that you can get interfaced with your computer. I would assume that most of us at congaplace have that.
The website interface defaults to your internal mic, so be sure to select USB mic (or whatever external mic your computer denotes) or you'll be sorry. I finally had a good enough take to save, and then on playback realized I had forgotten to change the default and it was a lousy recording.
You do need to put on the headphones like they say in the promo - this really gives you a much better handle on your mix.
Okay, I'll be recording a few things in there, and I figure we might have more fun if more people of the percussive nature descend on the site and start collaborating. Now it's mostly grunge rock and weird electric keyboard types. It's cost and spam free, so run by some decent folks.
Also, I'm "windhorsey" on skype if you want to add me for any other collaborative real-time chats.
