Tyler Joseph

From 4:06 to 4:14 it shows the face of the Yamaha S series synthesizer (which matches only the Yamaha S08). This is the synthesizer that Tyler uses in just about every one of his performances. Even though he refers to it as his "piano" it is simply the S08 inside of one of two piano cabinets making it look like a traditional upright.

There are a few shots of his "piano" as he calls it. You can see the it clearly from above in a picture from ERS 2016 Nashville, uploaded in October 15 2016. It has a few red paint or tape on it and he keeps an iPad on the piano aswell, but you can see it resembles the CP4

In this video, Tyler plays the song "Migraine" on a miniature piano keyboard given to him at the minute 0:46 mark. The keyboard generally runs for 49 U.S. dollars, but it has run for 39 at select retailers.

In the video "Twenty One Pilots EBS" by Ruslan Yarulin on YouTube, Tyler Joseph can be seen using the Yamaha S90 ES during the performance.

Tyler notes that the piano he is sitting next to is the first piano he ever bought. The Yamaha DGX 500 appeared around 2008, and the stand side view matches up perfectly. 0:48 enjoy!

In the video of the performance of "Trees" in Seattle during the Clancy World Tour, you can see that Tyler Joseph’s keyboard is about the size of a Nord Lead but has a different button layout. The keyboard matches the layout of the Nord Electro 6D 61 and features the preset Tyler uses during the song, as shown in a fan-taken picture. Additionally, the Nord Electro logo is visible during some parts of the video. This confirms that Tyler Joseph uses the Nord Electro 6D 61.
