As people might know, I've been more into guitar stuff but I've created a little something in MuLab 4, which seems to be a very nice app. People always talk about Reason or FL Studio, etc., but it's a very cool app.

I'm not a good ambassador of this program, since I'm not really into Electronic Music, but I had a lot of fun creating this.

You can get it at Mutools.com and there's no dongle needed. Oh and no install is needed either; just unzip it to a drive and it just works (even from usb stick). The free version has a 'hiss' noise when you cross the limitations that are set for the free version, but it's fully functional. Do read instructions on the website for more info.
