Play Rock Band Wii connect more than one instrument?
We have Rock Band. We are using regular microphones, a guitar, and now we have the battery. . . How do you hook them all with the dongles "?" when the port of Wii only has two slots for those? Are there other USB port where two instruments can be hooked into that and then break out in the Wii port? Help, we want to rock and sing and now, that sounds so sad! SMILE!
When you purchase the kit Full Store comes with a USB hub. Since you do not have to, you can buy any USB hub you would use to connect USB 4.3 for the Wii with to connect all the instruments. You'll find them in the computer section of any store that sells electronics. Want an active one because it takes a little power to operate each instrument and the wii could not wipe enough power through USB ports to handle it.
