The Roland FP-90X and Roland FP-60X are both high-quality digital pianos designed for different audiences and needs. While they share some common features, there are also some key differences that set them apart. Here is an overview of the features and differences of both models:

  1. Keyboard:

The FP-90X features Roland's PHA-50 keyboard, while the FP-60X features the PHA-4 keyboard. The PHA-50 keyboard offers a hammer action that authentically reproduces the touch of a real piano, while the PHA-4 keyboard offers a standard hammer action. In addition, the FP-90X's keycaps are made of synthetic ivory and ebony for a natural touch.

  1. Sound quality:

Both models offer excellent sound quality, but the FP-90X features an improved sound processor that enables even more natural and realistic playback.

  1. Polyphony:

The FP-90X has 256 notes of polyphony, while the FP-60X only offers 128 notes. This means the FP-90X can play and sustain more notes at once, which is especially beneficial when playing complex pieces.

  1. Features:

The FP-90X has a wider range of features than the FP-60X, including Bluetooth connectivity, USB recording capabilities and an internal multi-track recording capability. The FP-60X does not offer these functions.

  1. Price:

The FP-90X is more expensive than the FP-60X due to the additional features and higher sound quality.

In summary, the FP-90X performs better than the FP-60X in terms of keyboard, sound quality, polyphony and features. However, the FP-60X offers solid performance at a cheaper price and can be a good choice for use in home and practice environments. Both models are excellent options, but it depends on what features and requirements are needed for each application.
