Thank you Jeremy for this video! I’ve been waiting for it!

My Roland fp30x has been delivered 3 hours ago, right at the moment when you have published this video. It’s like „11 reasons why I have made a right choice“ for me. Thank you so much for the video 🤗

Between now and 2 hours from now, my FP-30X is gonna be delivered and I am beyond excited. I've never really been able to stick with learning the piano, because I used to have a cheap keyboard that I just didn't enjoy the sound of. With the amount of money I invested in this, I'm dedicated to start learning and be consistent.

I almost don’t care about extra sounds, playing the roland fp30x made me happy to be alive in 2021, it connects with the Soul, I played for 1 hr in the store and forgot where I was…

Very well put together Jeremy! I feel the FP - 30X is a better choice for those intending to play classical piano pieces by Mozart, Beethoven, etc. The Bluetooth Midi function is something really unique & useful as players don't have to carry their midi cables around. The DGX - 670 is a better choice for those who would love to play their favourite songs with super realistic voices and accompaniment. Another advantage is that the DGX - 670 comes with the 'Adaptive Style' feature that arranges accompaniment to suit the mood of the music.

Very good review, thank you Jeremy !!

As a writer and arranger, the DGX was an easy choice. I’m incredibly pleased with it.

Gracias Jeremy. Acabo de decidirme por el Yamaha DGX670 después de ver tu video, y otro más donde también hablas de este teclado. Saludos.

Very Good Solid info I loved it.😇

Nice analysis, really helps the decision process. Looking forward to similar reviews on the FP-60X, as I am already leaning toward that board. Thanks Jeremy

The hustler is back! He doesn’t skip a beat! Thank you for this great and anticipated review

Glad to hear about the hammer effects on the Yamaha. Now I know I am not the only one. I can really notice the big difference between my Acustic Jun109 and the GDX. Yes I agree I not comparing apples to apples but, I also have a very low quality digital piano from Alexis and the keys effects are much better than the other digital Yamaha. Yamaha makes greats digital pianos but they need to level up their key effects. Thank you.

Hi Jeremy I agree on all points excepted that if I had to choose, as a composer, I would certainly buy the DGX670 because of its numerous sounds and effects, styles and arranging functions. Are you going to foot another video to explain why the DGX 670 is a better choice than the Roland FP-30X for pianists wishing to compose and arrange songs? Have a nice Sunday 😎🌈

I just bought the DGX-670 for my family entertainment. I love it. The best feature of DGX is the Bluetooth facility. I play my favorite songs from Spotify, connected to the DGX then I follow the band and the singer. Made me feel like playing music and sing together with them. Duet with Fank Sinatra - My Way :). It's a best way also to learn a song (chord and melody). Thanks

Im waiting for this video THANK YOU SOOOO MUCH IT HELP ME A LOT 😍😍😘😘🥰🥰🥳🥳🤩🤩

Great video and the bonus cat cameo at 3.54 made it perfect.

My friend, it’s allways interesting to watch your video’s!

I truly enjoy your videos. Hopefully you make soon an review on Roland RP/F 701. As far as I understand the BMC the FP-30x and 701 is the same. Keep on posting🙂👍🏻

Great Review. I listened to both of your videos comparing the two ’pianos’. Yamaha seems to be a keyboard with a piano type action. The Roland is a piano with additional features. If you want to learn to play the piano then the Roland is the choice. In real life I’ve recently heard the comparison of sound and touch of the FP 30 X against the Yamaha. Frankly I don’t think there is a comparison. One sounds magnificent in comparison to the other. For an arranger on a budget the Yamaha might do. The operative word is budget. With the FP30X the operative word is piano. Keep up the good videos.

Thank you brother. What do you think piano sound cfx dgx670 vs supernatural fp30x? Do you think both equal?

I love how straightforward you are and start right away with the verdict at the beginning, so i can start googling the price as i was watching your video 😂😂 most vloggers just try to drag out the verdict at the end 😤

Sir I really appreciate your content it's ver helpful sir I had a few doubt that I would like to get clarified such as:Sir does CTX 700 has full size keys & does the CTX 700 lacking pitch wheel make a major difference as compared to cts-300 ,sir is the 20 piano rhythms in CTX -700 would be sufficient for a 'beginner' ? Would be thankful for your reply! Your thankfully, Tejas.

Hi Jeremy, great video thanks so much! I would like to know if fp 30x can play back what’s been recorded on the track and record at the same time? (Instead of overwriting the same track) thanks so much

GREAT REVIEW! WHICH OF THE TWO HAS A BETTER ACTION? SWEETWATER SALES PERSON SAID YAMAHA DGX 670 HAS BETTER ACTION? AND WHAT SOUNDS MORE LIKE A BABY GRAND? THANKS!

Thanks for the great videos. Do you ever review synthesizers?

Hi jeremy, Hi thank you for your demonstration very nice, I am an owner of a Roland G1000 and sadly the LCD is fading and I can't find a part, so I am looking for another portable keyboard, what my dilemma is I have always used the GS MIDI via the floppy discs for backing me up as a one man band, I realise that is very old technology, I am wondering as you say the Roland plays midi can I download all my midi files to a USB and plug it into the keyboard for playback as I dont want to mess with Ipads ect. or do you know of another model of any brand that can do this, your advice would be great await your reply with thanks Kind regards Noeline

If anyone need only piano they can go for Rolland... But I need electric keyboard, 88keys piano, styles, vocal input, all those stuff together in dgx 670...

If you want a PIANO with a smattering of additional sounds the Roland rocks. If you want great piano sound, not as good as the Roland, but hundreds of additonal patches, rhythm, accompaniments and a pretty decent keyboard get a Yamaha.

An excellent comparison. I love the DGX-670 I just purchased but your review is unbiased and much appreciated.

What piano do you think is the best for me to practice my practical piano class , p125 or fb30x ? all pianos in my college are acoustic and i don't want to feel any difference when i switch

Hi Jeremy compliments for your video!!!Can you make a review Roland fp90x vs Yamaha P 515? I must buy One of these Bye bye from Palermo

I just bought the DGX-670 - I had the 660 and 650 models. I'm going crazy trying to access the XG & GM voices...can't find them yet I see a list (Found it online) of all the additional voices within those areas for the 670. On my previous models (660/650) I could scroll through and find the all the voices together...what am I missing and how do I access the GM/XG voices - they should be loaded up onto my keyboard and not something I have to purchase additionally correct?

Not quite an apples to apples comparison, but everything Jeremy says here is sound. I still like the Yamaha's piano sound a bit more but at this point, Roland's piano qualities and timbre changes and dynamic control is closer to an acoustic experience than Yamaha's. However, if you want a low-priced piano arranger, the DGX-670 is quite a good value. Yamaha just simply needs to update their action on their lower end and start adding value because Roland and Casio really give you a lot of bang for the buck. And Roland is the bigger challenger because their name is big in the industry as professional instruments while Casio is still struggling to be seen as a major player in the middle and higher markets (though they should be, IMO).

Thank you for another great review Jeremy. My FP-30X arrived yesterday. I like it, but am considering returning it as the output speakers seem muffled. Is this a common complaint or do I need to configure the settings somehow? The sound is fine with headphones in. Thank you

wondering how is the sound of the DGX670 compared to your casio pxs3000 ? they cost the same. Also wondering about ES520 vs dgx670 which is also pretty similarly priced.

i m so hyped!!!my fp-30x is due to arrive in 3 days !!!hope my piano journey that starts at a boomer age of 33 wobt be too hard

I thought about an Yamaha YDP Arius 144, for that classic look. The 3 pedals. The seat. But I recall trying one out and not finding the sound "full" enough. Beautiful digital piano. My "noise room" is starting to get a bit cramped. I have a home built keyboard stand to hold my Keystation 88ES and then a regular stand behind that to hold my DGX220. Then behind THAT a laptop and Cerwin Vega VS120 speakers. In one corner I have a drumset, my Marshall halfstack and atop that a Fender 2x12 amp (I use this for my DGX 220, and use the Vegas for the Keystation while making music in FL Studio... need to get some good monitors some time, I know haha)

A ver tengo un yamaha Dgx 650 con su soporte original, estoy pensando en comprarme un dgx 670 el problema es que en mi país (España) el soporte original aun no ha llegado Pero yo creo que prácticamente son iguales Me serviría el soporte del 650 para el 670?? Porfa necesito respuestas

Price and functionality is more comparable between p515 and dgx 670. Can you please do a video comparison for the two?

Thanks Find it helpful.

Jeremy! Thank you for another super helpful video :D Another quick question: I know the Yamaha DGX 660 (and I assume also the newest DGX 670) can be used without a stand. Does the Roland FP-30X also allow for this? I am looking into most effective integrations of either of these keyboards into my home studio setup, and though I notice you use it right in front of your desk with the included stand, would it also work just as well as a standalone unit? Thanks so much, SERIOUSLY helping my search here! :)

Hi Jeremy Please help i am confused between Roland Fp30x & Roland RP501R. Which one is good?

can you save MIDIs from the DGX-670 you record and transfer to your DAW through USB? Cause after hearing about the Bluetooth MIDI on the Roland, I'm kind of going for the FP30X

Hi Jeremy, what would be the set up with roland fp30 in music recording or making cover worship music

At 2:00 you can see the lateral movement of the keys. It seems they didn't fixed that yet, it was one of the things that bothered me about the action.

I already play Pianoteq Pro powered by a Casio PX-150 with hi-res MIDI and triple sensors. From a key bed perspective it seems Yamaha could be a step down. That said, I think the arranger features of the DGX would be fun for me. As 78 year old pianist, I can fool around with just playing melodies and using the auto-accompaniment styles feature. While there are negatives to the DGX-670, I think I will go ahead with it. Of all the digital slab pianos on the market today I would actually prefer the Roland fp90x, but it is even heavier than the DGX and costs 2.5 x's more. Given that I already have a good digital piano set-up, the question is do I need to spend money on another piano at all?

it's worth noting that if glossy/untextured keys bother you, you can quite easily scuff them up with a very fine/high grit of sandpaper. but I'm talking VERY high grits, i'd be looking at something like maybe 1200. you can always go down or up a grit depending on the result. it may void your warranty, but worth considering

Jeremy, what do you think about Roland FP E50? Especially comparing with DGX 670. Thanks

Hello. Is the fp30x good for boogiewoogie style? Thank you.

I would like to see you do a comparison between the Yamaha P515 and the DGX-670. These two keyboards seem to be much more similar than the Roland FP-30x vx DGX-670.

I'm wary of the fp10 and fp30. I've read a lot on forums about the PHA4 keybed getting clicky soon after buying it - it's to do with the internal lubrication. Do you have any thoughts on this?

Although I already own a Fp 30x (yes, I bought it because of your previous videos), I still watch your videos just like how I watch other KZfaqrs' videos for leisure. Always good to watch and informative! Good job 👍

very informatibe video. I would love to see a video of all the sounds of the fp 30X. I need a digital piano with good strings sound :

Hi Jeremy, nice video comparison. I would like to add that the FP-30x is sleeker and more aesthetically pleasing to look at than the dgx-670 especially if you are placing them on an X stand, the dgx just looks odd even on its oem stand.

Can you please please please make a video on Roland Rp 302 Digital Piano??? Can I have your feedback on the Roland Rp302 here?

The microphone feature was not mentioned. Does the FP30X have a microphone input like the DGX670?

Hi ... I have recently purchased Roland FP 60X digital piano. But Piano Partner 2 app is saying incompatible with this model while installing the required data files. Piano Designer app is working normally. Is Piano Partner 2 app is incompatible? Then how to access in-built Rhythms and other hidden functions? Thanks

Have you try the FP E50 yet??? This would be the best rival for the DGX 670

Hi Jeremy , I am planning to purchase yamaha PSR SX900 in next 3 months, can you please help me know if yamaha is gonna launch any new equivalent keyboard in 2021 ? is there any way to find out same.

2:38 this is so satisfying

Hi Jeremy, thank you for this very helpful comparison. I have a question for anyone - Does the FP-30X or DGX6670 allow me to record and broadcast in real-time via computer? (Like for a live KZfaq video?)I have had the Yamaha DGX660 for several years and have enjoyed it. However, I would like the ability to set up live-streams to platforms like KZfaq and record directly on a computer. Although the DGX660 has the USB to Host port, it is my understanding that it does not allow live broadcasting or recording directly to my computer for both audio or MIDI. For recording, I have had to record directly on the device, then plug in a flash drive, transfer in real-time to the drive, then plug into the computer to save and upload. This is tedious/time-consuming and does not allow live performances online. So I am now looking at buying a second digital piano that will allow me to both live-stream and record directly through a connected computer. Do you know if the FP-30X or the DGX-670 (Or both) allow this feature? Or do you recommend a different digital piano altogether? Any info would be extremely helpful. Thanks!

Have you had a chance to play any kawai digital pianos for review? The es model line specifically, 110, 520, and the 920.

Personally I like the high end of the Yamaha grand better. Yamaha multisamples sound far more dynamic and realistic, to me anyway.

ROLAND FP 30X ELECTRIC PIANOS, DRAWBAR TONEWHEEL ORGANS & PIPE ORGAN SAMPLES ARE FAR SUPERIOR TO THE YAMAHA DGX 670 - ROLAND FP 30X 88 KEY GRADED HAMMER PIANO TOUCH IS ALSO PERFECT FOR ELECTRIC PIANO & PIPE ORGAN PERFORMANCE !! WELL DONE, JEREMY - YOUR AUDIO VIDEO PIANO REVIEW IS BALANCED BETWEEN ENTHUSIASTS & PROFESSIONAL MUSICIANS !! PROFESSIONALS KEYBOARD MUSICIANS KNOW THE SONIC DIFFERENCE !!

i just saved up, and bought the fp-30x as my first piano. I was going to go with the fp-10 but they were out of stock and after looking further into it i saw that the fp-30 was being upgrade, so i am really looking for to it's arrival

施老师，真希望牙膏厂能给这些稍微好点的电钢琴配上GH Action，每次都是GHS🤦‍♂️

Which one is best to buy ? Difficult to choose.? Which one do you recommend to buy?

Having a hard time finding one from one of my preferred dealers, but I'm not gonna lie - I'm a die-hard Roland fan, so the FP-30X will be the choice for my daughter. 🙂

Great review. The Roland wins, hands down...

Which one has warmer piano sound?

What's an affordable, for hobbyist pedal for an FP-30x?

The FP 30x with speakers below would mean that one cannot place it on a flat table?....as the speakers will be blocked out?

Jeremy, again you have explained everything very well, as did some of the others, elaborating on what you stated. My very talented keyboardist and singer friend Jeannette Casuga Trevias here in Honolulu is highly trained and accomplished, but gigs with an older Yamaha arranger keyboard most of the time. She has a KZfaq channel and goes live on Facebook, performing often several times a week, with other local music artists. She knows how to use the arranger keyboard very well. The DGX-670 is an awesome keyboard for what it does, and has great features for the price, but the FP-30X has a proven more professional keyboard action, keys and other features and connectivity. It all depends on what kind of keyboard player you are, your experience from you first learning and playing, your level of proficiency and musical training, knowledge and expertise, and technical acuity in regards not only to musical prowress and playing technique, but comprehending, and mastering alk the technicsl features and functions of these electronic keyboards, musical instruments and related sound and other gear. Sound quality of tones or patches are comparable, but if you were raised with traditional acoustic pianos, especially high quality upoer line ones, trained in serious classical piano and possibly pursuing that venue as a professional, the keyboard action like that of the FP-30X is essential. For others more interested in playing for enjoyment, entertaining friends, or the weighted hammer action and escapement is not a big deal, as they are just happy to be abke to play songs at various levels, or more pop synth and other music, the keyboard action is not as vital, and they may prefer the action if the DGX-670 or lighter action. For myself, coming from a long exposure to music, from playing piano, other instruments, especially clarinet for most of my school years, with relatives and friends as professional musicians and singers, I have learned to appreciate and constantly listen to music fron those with the utmost musical and technical abilities, but have a profound admiration, regard, and respect for those with superlative playing technique, creativity, improvisation, arranging and composing giftings, besides learning all the peripheral things I mentioned. Just to memorize everything, the knowledge, discipline and tenacity to perservere to their level of excellence is to be commended. Some doing it for recognution, wealth, and other goals, but most ultimately are driven and motivstiin by their love and passion of music. The most beautiful thing is, unless your livelihood depends on it, you are free to enjoy listening, learning and playing music to whatever degree or level you desire, and strive for whatever your goals, dteams, and aspiration are. But like I mentioned in my otevious long comment, be practical, and don't let it be an obsession and a compulsive thing and lose perspectives. Be practical and take your time. Use discretion and discernment and don't go overboard beyond your means or need to get something that will mskebyou neglect more important things in life. If you are an enthususst abd hobbyist, something like the $200 Yamaha PSR-E373 or Casio CT-S300 would be ideal. You can upgrade to something better when you reach that point and csn make use of it. I am willing to spend money on things I really want, but I have soent so much in the past on music gesr I did not make much use of or needed. Music is not my career, and time and energy impedes me from playing and getting back into learning and improving, so my Roland Go:Keys 61K is perfect for me at this point. Other than maybe another keyboard for my sister, which might be the PSR-E373, so I csn play that, too, and my JD-Xi synth, I will probably not may another keyboard other than one for church I can enjoy, but make use of there, so the purchase is justifiable. I took another look and listen to the videos, and like I decided to get my Go:Keys over the PSR-E373 for a little more, I would spend the $1200 on the Roland RD88 over the FP-30X and DGX-670. The sounds and features are incredible, and much more professional, along with that keyboard action. Both the FP-30X and tge DGX-670 are winners if it suits the needs of those that get it, and brings them joy. But for many here, the PSR-E373 or other affordable keyboards like those digital pianos with weighted action will suit many fine. Other than price, avaikability is a major factor.

Thanks for this review! (You may be living in a tiny appartment but your television set is designed for a loft 😉) )

Interesting comparison. I think the high quality samples of the Yamaha is what everyone raves about and tends to influence the rest of most reviews even causing some to disregard important shortcomings such as key action and lack of a line out. Hopefully, Yamaha's next DGX version will have a better quality keyboard with triple sensor and matte finish keys and also a proper line out. I had the original Roland FP-30 and using headphone out for an external amplfier didn't sound great. I now have the FP-30X and it's better. I do wish some of the Roland sounds were higher quality samples.

So tough trying to decide what to buy. An amazing piano sound is a 100% MUST. I want that deep, fully rich grand piano sound (or best as I can get for under 1500 bucks Canadian taxes in ideally), BUT I also enjoy dabbling with synth sounds (though I mostly do that with FL Studio plugins). I generally use things like Piano/Strings/Orchestral Brass Section, a nice cathedral organ sound would be good. I have an ancient DGX 220 that's getting pretty beat up (mostly by the previous owners), and the actions getting bad, keys sticking, keys banging, and I just want a really good upgrade that will keep me happy for the next decade or so. I looked at things like the Juno DS 88 for synth and piano, but found the piano lacking a bit. All the sub $1000 keyboards sound unpleasant.

previous video convinced us to buy Yamaha DGX-670

What is the difference between FP30 and FP30X please?

Thanks for the thorough assessment of pros and cons of each instrument. Definitely persuaded towards the Roland even though downward facing speakers look like a stand is necessary and not as suitable for desktop playing as the Yammi. Thanks again.

REMEMBER THE X! So much better than it's predecessor, The FP30. So -FP30- *FP30X* ! I'm buying one this week. Was considering the console digital piano ROLAND RP701, but out of my price range. A great alternative to the RP701 imho is the KAWAI KDP110. The ONLY deal breaker of the KDP110 is it is exclusive to APPLE TABLET editing. The KDP70 has excellent sounds, and is a console under $800! Limited editing, but doesn't really need it.

Seems like this is a bit of an apples vs oranges comparison with the DGX allocating a good portion of its cost on arranger features, but the Roland is excellent for its price point. If you are just planning to play at home, then the lower power, forward facing speakers and lack of dual output jacks are probably fine. (but we always want more..) You mention how heavy the DGX is with stand, but then don't mention the weight of the Roland with stand. I would imagine there are half a dozen features where the DGX stands out too. I would think that students should be concentrating on the piano and not have much time to get into the arranger features as well, so the Roland is better suited there. Thanks for your great video reviews!

Thank you for this video. It's really difficult to find this specific comparison because I guess they're kind of meant for different things. Could you compare the strings sounds as well? I really love piano+strings. PS: small feedback: it'd be great if you could include Kilograms for weight (and metric stuff wherever applicable). I'm really bad with unit conversions. 🙈 Thank you!

Your cat really cute.

As usual, an interesting review with the Roland a clear winner for those wanting a digital piano (and one that's genuinely portable). To be honest I couldn't see a significant difference in size, both being the same length (and height) - the extra 10cm (rough guess) in depth for the Yamaha not really a deal-breaker.But the weight difference certainly is! I couldn't help but wonder if the reduced depth of the Roland made a difference when playing between the black keys (an issue with the Casio PX-S1000/3000 models). But generally while the Yamaha is named a digital piano it's also an arranger keyboard of some merit, so these instruments are aimed at slightly different markets (despite Yamaha's nomenclature). Roland doesn't include arranger features so that allowed them to produce a better piano in the price range. You are thinking of your piano students where, clearly, the Roland is the better choice. But for the wider market your channel reaches, the combination of good arranger features in an 88-note piano can be the ideal mix (although I agree with you and Yamaha could have had a better piano in the instrument plus better amplification - given the space available for the speakers - while maintaining the price).

What is that first song u always play in your videos

Ordered my FP-30X yesterday. Should be here in a couple days! Now I'll be able to practice without disturbing my family at night and play on my acoustic piano during the day :)

Different types of instruments should not be compared. The Roland FP-30X is a stage piano, the YAMAHA DGX-670 is a combination of a piano and an arranger keyboard. The Roland FP-30X can be compared to the YAMAHA P-125 stage piano, but the YAMAHA DGX-670 can be compared to the CASIO PS-S3000, a hybrid piano and arranger keyboard.

Considering the one line out and weak speakers, what do you think is an easy external speaker solution for better quality sound at home on DGX-670 outside of using headphones?

Do you have a recommendation of a Piano that has the FEATURES of the Yamaha DGX-670 but also has the quality KEY Performance and SOUND of the FP-30X without having to pay $2,000 or something? I understand having to pay more, but don't want to go that high. I mean, it's astounding what the Yamaha can do in comparison, but I want quality sound and performance of the keys too.

Dang. You are really active in your comments section.

I'm only buying an beginner model for my kids, I don't know how to play piano at all but his video is really fun to watch while I'm eating some chicken and beer.

Very informative video, Jeremy. I love Yamaha instruments, like the PSR series, and others instruments lines as Pacífica, electroacoustic guitars, recorders and others, but your review is very massive. Roland f30 is a very good election if you learning piano. Dgx is better for the people who learn "keyboard style" , and arranger capabilitys. Thanks you, Jeremy, for this good comparison. (and for your Cat 😺) A big hug from 🗿Chile🇨🇱

I have loved the Roland keyboard because of its genuine sound ability, smoothness, warmth, and restful sound that generates pure beauty. I've also owned the Yamaha DGX650, and one of the older models from Yamaha, both models were definitely for the inexperienced musician, but I guess I've grown out of the need for bells and whistles.

Is yamaha P 125 still worth it in 2021? And is Yamaha P 125 good for advance or professional players? ADVANCE THANK YOU❤️🇵🇭

Hi Jeremy, excellent video once again, but you are comparing two different kinds of instruments for two different kinds of needs. DGX series is something between an arranger keyboard with (unlimited) styles, many voices (with hundreds of effects) and a digital piano. It is made specifically for piano players who wish to play also an arranger keyboard with styles but with 88 keys and a more realistic key action than the typical arranger keyboard. FPX series on the other hand, is a wonderful digital piano indeed, with the characteristics of this kinds of instruments. Great Key action, excellent piano sound with some extra really nice voices but with no effects, no pitch shift wheel and of course no styles at all. Your hands don't have to "leave" the keybed to push buttons while playing or to watch any screen as there is not any.

The Yamaha DGX is based on a home keyboard and therefore it will always sound thinner than a real digital piano, like the Roland FP.

Is it worth upgrading fp30 to fp30x?

Dont forget the CLICKING KEY NOISES that all Roland FP-series models have. Just google this issue and you will find that this is an unacceptable flaw of the piano line. Go for YAMAHA.

I heard that the action is not as responsive. Some players have problems with thrill or faster pieces.
