As a classically-trained pianist who has lugged his acoustic baby grand from apartment to apartment, the promise of a digital piano that finally delivers supremely realistic sound and keyboard action seems too good to be true.
I‘ve tested plenty of impressive models over the years as technology continued advancing, but that holy grail of authentic acoustic recreation in a portable, affordable package always hovered barely out of reach.
Until now. Kawai‘s latest Responsive Hammer Compact keyboard action paired with their much-lauded Harmanic Imaging piano sampling represents a seismic moment for serious pianists seeking a digital performance and practice instrument.
The Roland FP30X packs substantial innovations of its own too however, building upon decades of superlative gig-ready keyboards acclaimed by professional performers globally.
As an passionate musician always chasing that elusive keyboard feel and inspirational sound quality allowing me to lose myself fully in playing, evaluating these two instruments was akin to a personal moonshot.
Evaluating My Candidates Through The Ears And Hands Of Experience
Having tickled the ivories for 30+ years across everything from flawless Steinway concert grands to toy Casio keyboards as a 5-year old, I‘ve developed personal testing methodology leveraging:
- Anatomical ergonomics and playing dynamics
- Frequency spectra analysis of tonal output
- Feature set utilization for creative inspiration
I structure my reviews across four key pillars – Sound, Touch, Features, Versatility. Ranks are assigned in each sub-category on a 1-10 scale by evaluating real-world playing tests supported with measurement data.
Let‘s dig in!
Dimensionalizing That Sonic Quest For Acoustic Nirvana
| Digital Piano | Acoustic Piano Sample Quality | Available Instrument Voices | Harmonic Richness (1-10) | Resonance Modeling (1-10) | Note Decay Length | Key-Off Noise Audit |
|---|---|---|---|---|---|---|
| Kawai ES120 | SK-EX Rendering + 88 key sampling | 34 tones | 9.5 | 9 | 20 seconds (treble), 58 sec (bass) | Characteristic felt thump |
| Roland FP30X | SuperNatural + 88 key multi-sampling | 72 tones | 8 | 7 | 18 sec (treble), 47 sec (bass) | Faint hiss |
What immediately struck me about the ES120 is the three-dimensional sound immersion – those lower registers especially exhibit a gorgeous surround bloom that transports you. Chordal sequences reveal tremendously complex harmonics with the resonance modeling imparting so much warmth across the bass midrange in particular. The key-off noise lends an innately piano-esque following to note decays.
While admirably rich, the FP30X has a perceptibly brighter tonal balance more akin to a studio recording vs a naked piano. Comparing the amplitude waveforms shows a higher harmonic cutoff, reducing body in exchange for amplified clarity and articulation. This does impart a wonderfully crisp precision well-suited to certain musical contexts.
Across both, half-pedaling and rapid repetition of notes convincingly replicates the actual mechanical noises you‘d expect of hammer mechanisms and key beds. Impressive realism indeed!
Keyboard Touch Mechanisms Dissected And Critiqued
After years battling joint inflammation triggered by overly stiff digital piano actions, evaluating keyboard touches carries huge personal significance. I break things down thus:
- Weighted Key Tensions
- Velocity Sensitivities
- Key Pivot/Fulcrum Dynamics
| Digital Piano | Triple Sensor? | Weighted Keys | Touch Sensitivity | Pivot Simulation? | Let-off Feel? | Key Noise? |
|---|---|---|---|---|---|---|
| Kawai ES120 | ✅ | Graded across 88 keys | Off/Normal/Heavy (+ amp envelope adjust) | ✅ | ✅ | ✅ |
| Roland FP30X | ✅ | Slightly lighter but uniform | 5 Preset curves + user adjustable | ❌ | ❌ | ✅ |
The ES120‘s top-grade RHC action fitted with counterweights and unique simulation pivoting behavior makes a remarkable difference for this pianist battling joint issues. Rapid trills and lighter passagework proves far more comfortable over extended sessions given the smoother, forgiving response. The beautiful let-off simulation notably enhances playing control across ppp segments one struggles to properly voice on lesser actions. Little details like convincing damper/key noises further the realism.
Don‘t get me wrong – Roland‘s PHA-4 Standard keyboard feels wonderful with admirable consistency of touch. But the lighter weight does impart a certain ‘plinkier‘ sensation compared to the Kawai‘s meticulously crafted acoustic piano action replica. Those faux ivory textured keys look splendid too!
Augmenting Creative Flow Via Features & Connectivity
Beyond fundamental sound and touch, supplementary features enrich the overall user experience. Evaluating creative flow generating tools both inherited and unique to these instruments proved insightful too.
| Digital Piano | Score Viewer? | Audio Looper/Rhythm Accompaniment? | Lesson Songs/Exercises? | Onboard Sound Editing? | MIDI Controller Features? | App Integration? | USB Audio Interface? |
|---|---|---|---|---|---|---|---|
| Kawai ES120 | ❌ | 10 Rhythms | 12 Alfred Lesson Songs | 5 Acoustic Character Editors + Effects | ✅ | ❌ | ❌ |
| Roland FP30X | ✅ | 38 Rhythms + Recording | 15 Internal Songs + Curation via Piano Partners app | Tone Color (cutoff, resonance)+ ambience/EQ | ✅ | Piano Partners | ✅ 24 bit/96 kHz |
Here‘s where Roland‘s legacy as a premiere prosumer keyboards shines through! While light on notation abilities, they furnish tremendously versatile creative augmentation tools. The well designed rhythm accompaniments fuel inspiration during solitary practice sessions beautifully, while the USB audio interface with great latency specs makes integrating with production software buttery smooth.
The ES120 focuses more narrowly on supreme piano recreation accuracy. But the onboard sound editing and half-decent looper add welcome flexibility, while the huge array of tunings proves a customizer‘s delight. Notably absent are scoring capabilities, lesson augmentation or companion apps – quite surprising omissions at this price point.
Portability Permutations For Digital Nomads
As a temporarily mobility impaired musician this past year recovering from knee surgery, portability concerns occupied my evaluations prominently.
- Weight and dimensions
- Carrying mechanisms
- Stand/Pedal options
| Digital Piano | Weight | Width | Depth | Height | Handles? | Matching Stand? | Pedal Unit? | Headphone Hook? |
|---|---|---|---|---|---|---|---|---|
| Kawai ES120 | 11.2 kg (24 lbs) | 135.5 cm | 28.5 cm | 15 cm | Front integrated | Optional extra | Optional F-30 triple pedal unit | Side mounted |
| Roland FP30X | 14.5 kg (32 lbs) | 132.2 cm | 25.7 cm | 10.1 cm | Side inset handles | Included matching stand | Included RPU-3 triple pedal unit | Underside mounted |
The ES120 packs admirably compact dimensions plus a slender profile with conveniently accessible front handle. The integrated headphone hook and multiple sound/volume adjustment knobs also score big wins for convenience.
While wider, the Roland FP30X includes extremely well designed foldable braced stand plus integrated triple pedal unit upon purchase. Clever inset side handles plus the aforementioned audio over USB negate any cables entanglement issues too.
The Sum Of All Perspectives – A Passionate Pianist‘s Verdict
Nor the measurable metrics neither my reviewer rankings alone can do complete justice to the multidimensional grandeur I experienced during those blissful hours alternating between the ES120 and FP30X.
This journey traced my personal arc from teenage classical conservatory student to jaded hobbyist battling repetitive strain issues to renewed digital pianist utterly astonished at how authentically these instruments reproduce acoustic intricacies many believed still years from technically feasible replication.
So in shining the spotlight on the category leader here – which remarkable machine receives my wholehearted pianist endorsement?
In truth…both deserve immense praise pushing digital piano engineering undeniably closer to that mythical perfection state. ☺️ I could enthuse for hours on the FP30X‘s wondrous dynamic sensitivity or supernal selection of gig-ready sounds.
Ultimately though, my heart belongs utterly to the Kawai ES120 for condensing everything wonderful about playing piano into a slick 27-kg ingot of acoustic authenticity. 🎹
From the complex resonances and singing overtones blanketing me during sustained low notes, to the satisfying mechanical noises across the compact keyboard, this instrument bears unmistakable Kawai DNA extruded directly from their finest concert grands.
