I’ve changed up my home studio and no longer need this module. Every function works 100%. Includes the factory power supply. PlEASE NOTE: The male barrel connector on the power cord that plugs into the female jack on the back of the unit does not easily push into the unit.. nor does it easily fall out.. (such as if you were to accidentally trip over the cord.) It was loose when I originally acquired the unit, so a tech friend of mine fixed it SO THAT YOU MUST FIRMLY INSERT IT INTO THE JACK .And now, it’s a very good and tight connection for sure.! This Musebox has some excellent sampled pianos, & lush string ensembles among other samples. Those were my favorite. I’m including a copy of the factory CD which allows for various tweaks. I never bothered using any of the sampled instruments except for pianos and strings in my recordings and never tweaked anything. I’m including a copy of the factory DVD in case you do want to tweak it . If any questions, please ask!
