Don't hesitate to use old applications coming from the amiga on your pc, without emulation, for your pleasure. Among them, try the legendary Symphony tracker, available with a 3D background for Win32 and its amazing effects, in a single .exe that could be copied on a floppy disk. Mail me if you use it, just for fun

Two users at least here lol/
In a pro way, try Reason (a lot of studios create songs only with this tool and master them with Protools). Don't forget :
- protools (avid) to edit/master and exchange audio projects and say that you're a pro (the point of protools LOL)
- cubase (steinberg) or nuendo (from the same editor) if you have to work seriously with video files. Nuendo uses the cubase audio engine and offers more slots to load virtual instruments. Midi implementation in steinberg products is very nice.
- if you want to keep the amiga spirit, you could buy Samplitude (Magix).
Cubase could be your new BnP.
Good luck and keep your migs.
