Ain’t no April Fool: piano evoce ß

Posted on by

The Japanese Yamaha site posted information about a new app called “piano evoce ß”. I’m going to quote the site as translated by the Google:

This is an AI ensemble app that extracts the vocal part of your song and plays it back along with your performance. Feel free to enjoy playing together with your favorite songs!

Practicing the assigned songs alone will not increase your motivation. I want a session buddy who can arrange things freely! I want to be able to play my favorite songs with chords!

This software is a beta version service released primarily for technical verification and service experiments. We hope to continue to make improvements based on the opinions of our users.

piano evoce ß appears to be the next evolutionary step in the Chord Tracker family:

1. Connect your electronic piano/keyboard to your Mac via MIDI.
2. Analyze your own songs.
3. Start playing! When you play the chord displayed on the screen, the vocal part will follow your performance.

To use piano evoce ß, you need to register for a Yamaha Music ID account (free of charge).

Now, that’s pretty neat. Here’s my guess: Yamaha combined a vocal stem extractor with Chord Tracker. The screens look very similar to Chord Tracker. Given the reference to “service” and the need to have a Yamaha account, the heavy lifting (vocal stem extraction) is performed by Yamaha software running on one of its servers. There’s a bunch of terms and conditions to read and accept — Yamaha and its friggin’ lawyers.

The app has two ways of following the vocal part (quoting the usual minimalist manual):

  • Gentle tracking mode: This mode gently follows your playing. The high degree of freedom allows you to arrange and play chords. Even if the performance stops in the middle of a song, the tempo will slow down, but playback will not stop. The AI listens to your chords and sense of rhythm, understands your playing pace, and sings in a way that feels natural to the AI. Avoid sudden tempo changes, and try playing together to create an ensemble.
  • Perfect tracking mode: This mode waits and follows your performance. It will wait until you play at least one note that makes up the correct chord. AI will play according to the timing of your performance. Be sure to play in time with the chord changes.

Can’t wait to try this! I’m guessing it will be available for Clavinova digital pianos and Yamaha arranger keyboards. Bad news for Windows users: “piano evoce ß can be used with macOS 12.0 or higher”. Not a word about Windows.

New year, new piano

Posted on by

Happy New Year!

It’s been a pleasure to ring in the new year with a Yamaha CSP-170 Clavinova Smart Piano. If you’re not familiar with the CSPs, check out my articles about the CSP-100 series and the now current CSP-200 series.

In short, the CSP pianos combine Yamaha’s Clavinova piano technology, learning features (score display and playback, stream lights) and basic auto-accompaniment into a single traditional home piano form factor. The CSPs eschew a complicated user interface, opting for a minimalist, two-button front panel: power OFF/ON button, FUNCTION button, and volume slider.

First and foremost, CSPs are Yamaha digital pianos, as Yamaha likes to say. In this post, I concentrate on the CSP-170 as a home piano. I bought the CSP-170 at a close-out price as Yamaha was clearing inventory when Series 200 deliveries began.

Appearance

I rarely discuss an instrument’s physical appearance in much depth as synth and arranger front panels are “seen one, seen ’em all.” The CSP-170, however, sits in our high-traffic dining room. You can’t miss it!

Yamaha CSP-170 Smart Piano (matte black)

Our CSP-170 is the matte black model. The matte finish is the best match for our contemporary house. The matte black model costs a bit less than the polished ebony — not really a concern.

The CSP-170 looks like the traditional spinet piano — the old family piano that we ditched just before moving out West. The CSP-170 has attractive clean lines and fits into the contemporary styling of our home. As a piece of furniture, it is constructed solidly and feels like a quality instrument. Definitely a step up from Arius.

I originally considered a P-515 “portable” digital piano and stand. When Yamaha announced close-out pricing, it made sense to step up to the CSP-100 series. A P-515 on its stand is not as physically attractive or formal as the CSP. The CSP cabinet allows for a better more powerful sound system than the P-515 as well.

CSP-170? Heck, yeah.

The CSP-170 piano samples and playability are on par with the P-515. The main pianos are the Yamaha CFX and Bösendorfer Imperial. I played them both during my piano quest and I still enjoy playing them today.

I prefer the CSP-170 sound system over the P-515. The CSP-170 has bi-amplified speakers: woofers in a downward facing speaker box and mid/high ports left and right at chest level. The P-515, like many portables, has bi-amplified upward firing speakers. The P-515 sounds brighter due to the direct sound from its speakers. The CSP-170 sound field is similar to a spinet; the sound is indirect and takes some of the edge off the CFX. My only knock on the sound system — auto-accompaniment lacks air and sparkle. You won’t hear snappy snares.

I should note that I also play MODX and Genos, both through studio monitors. Thus, I’m used to a crisper sound for auto-accompaniment and percussion.

The CSP-170 provides plenty of volume. I don’t practice at thundering volume and setting the volume slider somewhere near the middle is adequate.

I’ve been playing the CSP-170 for one month, mainly piano. It is so convenient to push the ON switch and play. I can sneak in short playing sessions while waiting for my spouse to get ready for our daily walk, etc. The minimalist user interface is not an issue for quick play as one can select one of the main voices (CFX, Bösendorfer, Suitcase Rhodes, Wurli) by holding the FUNCTION button and hitting the appropriate key. I keep a function cheat-sheet on top of the piano for reference.

Full functionality requires the Yamaha Smart Pianist app. The app is handy, but most times, I haven’t needed it. I’ve tried a few of the Smart Pianist features: stream lights, score display, song and score playback, and auto-accompaniment. I’ll have more to say about them in future posts. So far, my only knock against them is the rather poor written documentation. Yamaha provides the bare minimum and neglects to explain certain notable features (e.g., adaptive styles). The written documentation understates the advanced capabilities built into the CSPs and the Smart Pianist app!

Smart Pianist Piano Room lets you set the lid position, brilliance, Virtual Resonance Modeling (VRM) and more. Once you get the desired piano tone, save all the settings in a Registration for recall later.

NWX keyboard action

I suspect that the CSP-170 is the last instrument which Yamaha will make with the Natural Wood Escapement (NWX) action. If you browse the forums, you’ll see all kinds of comments about NWX, or this, or that. My advice is to go out and play a variety of brands and actions. Then choose. Ignore “action trolls.”

I find the NWX to be smooth with a weight letting me control the piano sound — to play in a nuanced way. (It might not work for you and that’s OK.) The NWX does not trash my hands unlike GH3X, GHC and, yes, the new GEX Montage M8X keyboard. When you try and test, be sure to play for an extended period of time. Then ask, “How do my hands feel?” NWX passed this test for me several times over.

Dealers provide a valuable service in this regard. It took me months and multiple playing sessions to arrive at my choice. Be sure to patronize the dealers who help you out even if the price is a little higher. They’ve earned it.

Summing up

Would I buy the CSP-170 again? At the close-out price ($3,600 USD), absolutely. The CSP-200 series models have a number of improvements (GrandTouch, more voices, more styles, both CFX and Bösendorfer binaural) at a higher price. If you try an NWX (maybe a P-515?) or a GH3X and you like it, there are still CSP-100 series pianos available at close-out pricing. It’s first come, first served, limited quantity only.

Yamaha would need to completely blow me away with the CLP-800 series in order to get me to upgrade. Seriously, I’m good.

Yamaha CSP-170 in the house!

Posted on by

At long last, my Yamaha CSP-170 Smart Piano arrived!

Classic Pianos Bellevue

Before saying anything else, I want to give a shout-out to Classic Pianos in Bellevue, Washington. I got a friendly and welcoming reception when I visited their showroom in August during my piano quest. I like to support local dealers when possible and Classic Pianos left me with a very positive first impression. [They had to endure my banging around, too.]

Yamaha CSP-170 Smart Piano (matte black)

So, when I heard about close-out pricing on CSP-100 series pianos, I gave them a call. They checked out the situation with Yamaha and offered the reduced price on the Yamaha CSP-170B (matte black) model. The only catch was availability because they needed to place an order with Yamaha. Classic Pianos staff were helpful and courteous during the wait — even checking on the status of their order with Yamaha.

Classic Piano rolled in “white glove” delivery which I did not expect at the close-out price. CSP pianos are quite heavy and assembly would have been a real chunk for two 70 year-olds. Thus, I’m really grateful for the extra service. Martinson Piano Moving handled delivery and in-home set-up.

At this point, all is well. Thank you, Classic Pianos (Bellevue).

Why CSP-170?

Yeah, why? The CSP-170 is the “old” CSP-100 series, right?

If you read my reviews of the Yamaha P-515 and CLP-785, you’ll know that I like the NWX keyboard action and the CFX/Bösendorfer piano sounds. I would have loved to buy the CLP-785, but its price is above my target budget.

My biggest beef with the P-515 (and the CLP series, for that matter) is the relative paucity of secondary sounds. Once you’ve tasted Yamaha MODX or Genos, you know what Yamaha is capable of. The P-515 XG sounds are sufficient for playing back XG MIDI files, but the voices aren’t up to the same quality level as mid- to upper-range Yamaha arranger keyboards or synths.

When the CSP-100 series was first announced, they struck me as innovative, but price-y. The CSP-170 (and 150) secondary sounds are roughly the same as the PSR-SX700 arranger. The extra sounds pushed the initial CSP-170 price ($5,400 USD) above the somewhat comparable CLP-745 (as far as base piano and sound system are concerned.)

Yamaha announced and began shipping the CSP-200 series last Summer. The second generation CSPs have a larger secondary sound set and GrandTouch keyboards. Pricing with respect to CLP remains high due to the CSP’s extra features.

For whatever reason, CSP-100 series were (are?) overstocked. [You can still find close-out CSP-150 and CSP-170 pianos today.] Yamaha reduced the price of the CSP-170B (matte black) model to $3,600 USD. A P-515 package for home costs about $2,000. So, the $1,600 delta above the P-515 buys a very nice cabinet, a superior amplification system, auto-accompaniment, learning features (stream lights) and a wealth of high-quality secondary sounds. Buying a CSP-170 for $3,600 is a bit of a “no brainer”, if you don’t want or need quasi-portability.

As I mentioned, the only catch is availability and waiting time. In a recent earnings call with financial analysts, Yamaha admitted that they have inventory issues and are over-stocked in certain specific product categories (e.g., entry-level digital pianos). Some of the glut is pandemic-related; some excess inventory is due to a slowed Chinese economy. Yamaha may be shifting stock from far away, for all we know. My CSP-170 was manufactured (Indonesia) in November 2022. I’d love to know its history!

Here I am today, a happy camper. I’ll be posting my initial impressions as a new owner/player and will have more to say about the Yamaha Smart Pianist app. Please, stay tuned and thanks for reading.
