Hammerhead does not work, despite the fact that it was listed as working many years ago. Here's the link to the download: http://www.threechords.com/hammerhead/download.shtml I also couldn't get Drumbox to work: http://www.threechords.com/hammerhead/drumbox.shtml I also tried the d-lusion Drumstation without success: http://www.d-lusion.com/ProductsDrumstation.html They all work fine in Windows XP. Do I need to have the .exe file in a special place of the directory before executing? Is there some special sound driver I need? These drum machines do not need ASIO and I also installed Soundplant (also a sound utility) without problems.
