There’s enough support out there
It all started out so innocently enough, didn’t it? The rhythm genre had a few hits, thenGuitar Herocame along, and there was just a few guitars to juggle. ThenRock Bandcomplicated things by adding more plastic to the heap, and with each iteration, more and more “pro” instruments (and the keyboard, RIP) came into the mix. It’s nearly impossible to keep track of, but we have a full/comprehensive list forRock Band 4andRock Band 4 Rivals.
How hard is it to get theRock Bandlegacy game controller adapter in 2023?
Well, it’s not easy! Although they were sold for a fairly reasonable MSRP at launch,Rock Bandlegacy adapters commonly go for hundreds of dollars on eBay. Confirmed sold listings in 2023 show anywhere from $126 (which is a rare price) to $210, to $250, to $300+.
They’re still selling weekly as folks pack up their plastic instruments and get rid of Rock Band, so make sure to set up alerts and check back regularly for a good lot.

How do you use theRock bandlegacy adapter?
ensure your console is turned on and you haveRock Band 4running.
Make sure your Legacy Game Controller Adapter is plugged in to your console.

verify your music game controller that you are trying to sync has fresh batteries.
Press and hold the sync button on your instrument. This is found in the center of your drum kit or next to the D Pad on your guitar.

A light should turn on and start blinking slowly. This means the controller is waiting to sync.
AT THE SAME TIME: Press and hold the sync button on the Legacy Game Controller Adapter and press and hold the small wireless button on your music controller (forRock Banddrums, this is a button found on the bottom left side of the main center brain. ForRock Bandguitars, this is a button found where the amp plug would be). You only need to hold down both of these buttons for a maximum of two seconds.

The green light on your legacy instrument should start rotating around. This means the controller is trying to sync with your console. After a few moments, it will stop blinking and a steady green light will show up in one of the four corners around the symbol to symbolize what player the controller is synced to (Player 1, 2, 3, or 4). If the green light is steady and not blinking, this means your controller has synced.
If your controller continues to blink slowly, repeat step 6 until the light becomes steady. Make sure to press BOTH sync buttons on the Legacy Game Controller Adapter and the game controller at the same time!

Once your controller has synced, press the Start button to officially get in game and rocking!

Rule number one: make sure if you’re tracking down old instruments, to keep them within the same console family (PlayStation to PlayStation, Xbox to Xbox).
