Like the Casio, the Yamaha has a duet mode that allows two people to play in the same register at the same time. However, the P-45 has only one headphone output, so you’ll need a splitter for both players to use headphones while playing together. The headphone jack is located on the back panel of the keyboard, making access a bit more difficult than with the Casio’s front-mounted jacks. The console controls are minimal, and while Jack liked the simplicity, Brent and I found them unintuitive.
Since there are so many digital pianos worthy of your attention in this catalog, you may want to narrow down your choices using some of the search options on the sidebar. For example, if you select stage digital pianos under the category section, you'll be presented with all the digital pianos that were made for the stage. Once here you have the opportunity to drill down even further and can search by topics like number of keys, MIDI/USB Connections or by whether or not the digital piano has built-in speakers.
