Kawai CA99 vs Casio GP 510 - Hybrid Digital Piano Action
Casio’s 88 Wooden Key Natural Grand Hammer Action Keyboard Designed by C. Bechstein
If there's a centerpiece to the Celviano Grand Hybrid GP-510, it is the action. The big thing that catches people's eye is the fact that this action was designed in collaboration with German piano maker C. Bechstein.Improvements Over the Previous Generation Action
One of the things that we thought needed some tweaking with the previous version of this action found in the GP-500 was some additional regulation at the factory - the touch felt a little bit loose which was a shame since the concept was clearly so great.Real Hammers
A very cool feature of this action is the fact that it actually uses real hammers, and the cabinet is designed in such a way that you can actually prop open the top lid the see the hammers in action.Textured Keytops
The white keys feature a polished plastic that is different than the exaggerated key texture most of their other digital piano actions have. This one actually provides a little bit more grip than we prefer, though that should get better with time as the natural oils from the player’s skin get worked in.Casio GP 510 Action Wrap-Up
This Casio Grand Hybrid is offering a super authentic action overall with very believable dynamic weight. We think that for the price point, this has got to be one of the top two or three actions available, and some folks will definitely find the touch response superior to the CA99.Kawai’s Grand Feel III Action
The Kawai CA99 digital piano is an instrument that we have reviewed in quite a few contexts on its own in comparison to a few others on our YouTube channel, so we’ve talked a lot about the Kawai Grand Feel III action (GFIII), which is also featured in the Kawai CA79.Extended Length Key-Sticks
The Grand Feel III action actually uses the same key stick length as what you are going to get on an upright piano as opposed to a grand piano. Even though it's called Grand Feel III, the dynamic and the static resistance actually feels closer to what you might find on a Kawai K200 or K300 upright versus what you'll get on a Kawai grand.Triple Sensor Key Detection, Counterweights & Let Off Simulation
A couple of features worth highlighting on the GFIII are the triple sensor, counterweights and let-off. Triple sensor key detection means the GFIII is capable of very accurate MIDI output and a wide range of dynamics. This is as good as it gets before getting into the advanced optical sensor technology found in the NOVUS series.Ivory Touch & Ebony Touch Key Surfaces
The GFIII has very nicely textured keytops out of the box on both the black and white keys, which we definitely prefer to the GP510’s action as they provide just the right amount of grip and glide.Kawai CA99 Action Wrap-Up
Kawai’s Concert Artist series digital pianos always feature great action, and the GFIII is no different. We think both actions are going to be satisfying to just about everyone, but if you have a chance to play both the GP510 and CA99, odds are you will prefer one action over the other based on your playing style.Kawai CA99 vs Casio GP 510 - Hybrid Digital Piano Sound
Shigeru Kawai SK-EX Resonance Modeling Engine with Multi-Channel Sampling
There are many aspects of the tone on the CA99 which are noteworthy and worth exploring. When you fire the CA99 up, it defaulted to ‘Piano Mode’ which features Kawai’s latest SK-EX Rendering engine which complexes with multi-channel 88-key stereo sampling with advanced modeling technology.Unlimited Polyphony
When you’re in Piano Mode, you get unlimited polyphony to work with. That means we could play hundreds and hundreds of notes, and the instrument is going to continue to be able to sustain and render, and create those tones without ever running out of memory. And it's one of the first times Kawai has released an instrument that has that type of technology.Harmonic Imaging XL Engine
When out of Piano Mode, Sound Mode engages, and this utilizes Kawai’s Harmonic Imaging XL (HIXL) engine. There are additional acoustic piano patches available with this engine, along with all of the non-piano tones which can be navigated via the LCD touchscreen. It’s very interesting to toggle between both modes to hear the very clear differences.Kawai’s Virtual Technician Feature
With Kawai’s Virtual Technician feature engaged, the user gets access to a whole bunch of editable sound-related parameters beyond things like reverb. string resonance settings and getting into the touch curve, voicing, damper resonance, damper noise, string resonance, undamped string resonance, cabinet resonance, key-off effect, fallback noise, hammer noise, hammer delay, top board, decay time, release time, minimum touch, and more.Soundboard Speaker System
One of the highlights of the CA99 and the one feature that firmly establishes it as a Hybrid instrument is the real solid spruce soundboard. Even without the soundboard, the 6 speaker system is already impressive with top speakers plus speaker diffusers and 2 dome tweeters, but the magnet-driven soundboard with 360-degree diffuser panels takes things to a whole different level.Casio’s AiR Grand Sound Source
Casio is using the most advanced version of their AiR Sound Source in the GP-510BP, which stands for Acoustic & Intelligent Resonator. This engine also features the most sophisticated version of their Multi-Dimensional Morphing technology which serves to facilitate the smoothest possible transitions across various dynamic levels.256-Note Polyphony
The AiR Grand Sound Source features 256 notes of maximum polyphony across its 35 total presets. You might be disappointed seeing this in comparison to the CA99’s limitless polyphony on piano tones, but you really shouldn’t be.Acoustic Simulator
Casio has their own version of user-editable sound-related parameters, which they refer to as the Acoustic Simulator.Grand Acoustic System (Speakers)
Casio refers to their speaker set up here as the Grand Acoustic System. They’ve given the speaker system this fancier name to show their intent of specifically configuring the speakers in such a way that they recreate the 360-degree experience of playing a real acoustic grand piano.Sound Wrap-Up
Both pianos bring advanced, high-tech sound engines and speaker setups to the table. At the end of the day, individual preference is simply likely to go to whichever core grand piano patch you happen to prefer, though we could see those in the Worship community prefer the Kawai CA99 due to how fantastic the organ sounds come across thanks to the soundboard speaker system.Additional Features & Connectivity
Functions
Both pianos offer a pretty standard array of functions with things like Layer, Split, Duet, Transpose, Metronome, Drum rhythms etc.Cabinet
The GP-510 is available in a gorgeous polished black cabinet with brass accents that is set to be a show stopper in any room, especially with the gold Bechstein logo. The lid height is also adjustable. The CA99 is available in a variety of finishes - Premium Rosewood, Satin White, Satin Black as well as Ebony Polish for a premium. Kawai also incorporates their slow-fall fallboard as well.Pedals
Both pianos feature built-in 3 pedal systems (damper, sostenuto and soft pedals) with half-pedal support. In the CA99’s case, it features Kawai’s Grand Feel Pedal System which is weighted exactly the same as a grand piano.Connectivity
Both the CA99 and GP510 have a pretty similar set of connectivity jacks, with the exception of the fact that the CA99 has both Bluetooth MIDI and Bluetooth Audio, with APTX support.Closing Thoughts
It’s fair to say that we’ve got two highly compelling flagship pianos from two of the world’s leading digital piano manufacturers. Warranty coverage is great on both, as is the overall aesthetic effect each piano possesses.The post Kawai CA99 vs Casio GP 510 | Hybrid Digital Piano Review & Comparison first appeared on Merriam Pianos
