Hello,

Lately I've been using Sony ACID Pro 7 with an Oxygen 61 midi controller. Any midi keyboard should work. Acid Pro lets me load all the VST's I have on my computer if you tell it where the files are. This is way cool for me as it allows me to use the best sounds from several programs in one VST host. I haven't tried it with my Tyros 4 yet, but plan too. -charley
