Scratch

I've been toying around with the free Pluto2 synthesizer yesterday and today, and I thought I'd share the first result in case you'd want to use it in a project 

I'ts basically an electronica background loop that sounds like it's being played in huge factory hall with an extremely cheap drum machine sound xD And it sounds industrial (hence the name)

So, here's the link:

It doesn't sound that good in the online player, it adds a tiny pause before the song restarts but, in Scratch, if you tweak [play sound [] ] and [wait ( ) ] a bit it should be ok.

And here's the link to Pluto if you want to try it too    (you should)

I think you need Microsoft Silverlight though.
