C418, dto, and a few others have created a specific place for musicians in the Tigsource community to hang out on IRC. Anyone who's a musician of any sorts is welcome to come join the channel. The channel is invite only to keep the trolls and other riff raff from espernet out so you'll have to message me (KM), Dragonmaw, dto, C418, Drakkar, or anyone else in the channel to get in. You should be able to just view the member list and pick someone to message, if not, I'm online in the channel 24/7. Message me and I'll let you in as soon as I can.
The server: irc.esper.net
The channel: #tigIRC
Also to note, we're trying to keep it musicians only right now. Sorry.
(You probably wouldn't of wanted to hear us talk about tweaking samples and buying plugins on sale anyway.)
