The way it works is that you download the Free version of the NEW MIDiculous 4 (The old Version 3 won’t work) and unlock the Pro or Player Feature. If you do not already have a copy of the MIDIculous 4 with serial, then this expansion will not work. There are no downloads or no software to download. Our system is automatically programmed to unlock the expansion pack inside of MIDIculous 4 FREE player. MIDIculous 4 Free is the only version needed. Purchasing this expansion unlocks features in that version, if and only if, you purchase them together or you have already purchased it. Our system needs to look at your MIDIculous 4 serial to automatically unlock it.
After purchasing, you simply go to the wrench icon (Settings) and then License. Hit Refresh and the expansion will unlock.
