Keyboard Action and Feel
One of the most important aspects of a digital piano is the keyboard action and how closely it replicates the feel of an acoustic piano. Yamaha is known for its expertise in crafting realistic keyboard mechanisms, and both the DGX-670 and P-225 showcase this craftsmanship. However, their differing key action systems—Graded Hammer Standard (GHS) in the DGX-670 and Graded Hammer Compact (GHC) in the P-225—reflect the priorities and intended audience for each model. Let’s delve deeper into the tactile experience these two instruments offer and what it means for different types of players.
Understanding Weighted Action: GHS vs. GHC
Yamaha employs a graded hammer action system in both models, meaning the keys are designed to mimic the feel of an acoustic piano, where the lower register keys are heavier and the higher register keys are lighter. This gradation creates a more authentic playing experience, particularly important for developing proper finger strength and technique.
Graded Hammer Standard (GHS) – Yamaha DGX-670
The GHS action is Yamaha’s tried-and-tested entry-level weighted action mechanism. It’s a staple in many Yamaha digital pianos and is designed to provide a realistic yet accessible playing experience.
- Key Weight: The GHS action features progressively weighted keys, with the bass keys being noticeably heavier than the treble keys. This simulates the physics of an acoustic piano’s hammer system, where larger hammers strike lower-pitched strings, requiring more force.
- Feel and Responsiveness: While the GHS action is less advanced than Yamaha’s higher-end Graded Hammer 3 (GH3) or Natural Wood actions, it is still highly responsive and satisfying to play. The keys feel solid and provide adequate resistance, especially for beginners and intermediate players.
- Surface Finish: The black keys feature a matte finish, reducing slipperiness during long practice sessions. However, the white keys are glossy, which might feel less premium for advanced players accustomed to ivory-textured surfaces.
Graded Hammer Compact (GHC) – Yamaha P-225
The GHC action is a more recent addition to Yamaha’s lineup, designed specifically for compact digital pianos like the P-225. It prioritizes portability without sacrificing the weighted action essential for serious pianists.
- Key Weight: Like the GHS system, the GHC action employs graded weighting to replicate the natural progression of an acoustic piano’s key resistance. However, the GHC mechanism is slightly lighter overall to accommodate the P-225’s portable design.
- Feel and Responsiveness: The GHC action offers a smooth and consistent response across all keys. While it doesn’t provide the same degree of heft as the GHS, it strikes a balance between portability and a realistic piano feel, making it an excellent choice for musicians on the go.

Connectivity
The connectivity options of a digital piano determine how easily it can integrate with external devices and software, enabling enhanced functionality for recording, performance, or practice. Both the Yamaha DGX-670 and P-225 offer various ways to connect to other equipment, but they target different levels of versatility. The DGX-670 caters to advanced users with a broad range of connectivity options, while the P-225 focuses on simplicity and essential connections to maintain its portability and minimalist design. Let’s explore the differences and implications of their connectivity features in detail.
Yamaha DGX-670: Versatile and Comprehensive Connectivity
The Yamaha DGX-670 is designed to be a multifunctional digital piano, and its robust connectivity options reflect this. Whether you’re a professional musician, a composer, or a hobbyist, the DGX-670 provides multiple ways to interface with external devices and integrate into complex setups.
USB to Host and USB to Device
- USB to Host: This port allows you to connect the DGX-670 directly to a computer, enabling MIDI and audio transmission. It’s ideal for recording MIDI tracks in DAWs (Digital Audio Workstations) like Cubase, Logic Pro, or GarageBand.
- USB to Device: This second USB port supports external storage devices such as USB flash drives. You can use it to save performances, load MIDI files, or transfer audio recordings directly from the piano.
Bluetooth Audio
- The DGX-670 includes Bluetooth audio capabilities, allowing you to wirelessly stream music from a smartphone, tablet, or laptop through the piano’s speakers. This feature is especially useful for playing along with backing tracks, learning new songs, or simply enjoying music playback without additional cables.
- However, it’s important to note that this is Bluetooth audio only, meaning you cannot use it for MIDI connections or wireless control.
Line Outputs
- The DGX-670 is equipped with dedicated line out jacks (1/4-inch L/R outputs). These allow you to connect the piano to external amplifiers, PA systems, or recording interfaces, making it a great choice for live performances or professional recording sessions.
- Unlike relying solely on headphone jacks for external sound output, line outs provide a cleaner, balanced signal optimized for high-quality audio production.
Microphone Input
- Another standout feature of the DGX-670 is its microphone input. You can plug in a mic directly and sing along while playing, with the piano offering built-in effects like reverb and EQ to enhance your vocals. This is particularly useful for singer-songwriters or performers who want an all-in-one setup.
Yamaha P-225: Streamlined and Practical Connectivity
The Yamaha P-225 adopts a more minimalist approach to connectivity, in keeping with its lightweight and portable design. While it doesn’t offer the advanced options of the DGX-670, it still provides enough functionality for casual players and gigging musicians who need a straightforward digital piano.
USB to Host
- Like the DGX-670, the P-225 features a USB to Host port, which supports MIDI connectivity. This allows you to:
- Connect the piano to a computer for MIDI recording and playback.
- Use it as a MIDI controller with DAWs or virtual instrument software.
- While it lacks the USB to Device port found on the DGX-670, the Smart Pianist app compensates by offering additional functionality through mobile devices.
Smart Pianist App Integration
- The Smart Pianist app serves as a bridge between the P-225 and external devices, enabling you to:
- Access additional voices and settings.
- Record and playback MIDI performances.
- Display chord progressions or sheet music for learning purposes.
- The app relies on USB connectivity but eliminates the need for an onboard LCD screen, keeping the piano compact and user-friendly.
Lack of Line Outputs
- The P-225 does not have dedicated line outputs, which can limit its versatility for live performances. Instead, users must rely on the headphone jack for connecting to external amplification or PA systems. While this is sufficient for basic use, it may not provide the same audio quality as the line outs on the DGX-670.
No Bluetooth Audio
- Unlike the DGX-670, the P-225 does not include Bluetooth audio. This omission is understandable given the P-225’s focus on simplicity and cost-effectiveness but may be a drawback for users who enjoy streaming music wirelessly through their piano’s speakers.
