Smart Pianist Audio-to-score tutorial

Posted on by

The Smart Pianist audio-to-score feature generates playable notation (a score!) from an audio song (e.g., MP3, AAC, etc.) Check this short Smart Pianist demo video. Kraft Music has a longer demo video featuring Gabriel Aldort from Yamaha.

Audio-to-score is so cool, Yamaha uses it to tease CSP series and CVP-800/900 series sales. That’s right, you need a CSP or CVP-800/900 to unlock audio-to-score in Smart Pianist. If you don’t own one of these models, you can still generate a chord chart using Smart Pianist or the Yamaha Chord Tracker app.

Smart Pianist has Chord Tracker technology inside. This tech analyzes an audio file and extracts the chords. It also identifies the tempo, key, and song sections (verse, chorus, etc.)

Smart Pianist can display a chord chart — sort of a lead sheet without melody. [Smart Pianist cannot extract melody. Yamaha is probably working on that…] If you know chords, you can play along with the audio song. Smart Pianist highlights the current position in the song making it easy for you, the player, to follow and play the next chord, or play your own melody to fit the current chord.

Not everyone knows chords. Possibly, you may feel musically stuck and want to try a new complementary keyboard part to fit an audio song. That’s where audio-to-score comes into play.

Smart Pianist has a “library” of forty accompaniment patterns. The patterns range from simple “block” chords to arpeggiated chords in both even (straight) time and triplets.

Smart Pianist applies your chosen pattern to the chord chart and displays the result on a grand staff. The word “chosen” is important because you select the pattern from the available accompaniment patterns to fit what your inner arranger wants to hear. This is a handy capability if you’re stuck for ideas and want to try something new with your hands. [It’s a more interesting practice tool than Hanon exercises, too.]

Example song: It’s Too Late

After launching Smart Pianist, tap the “clover” menu in the upper left hand corner of the screen.

Smart Pianist displays the top-level menu shown above. [Click the image to enlarge.] Tap the Song button to select and play a song (audio, MIDI, or PDF score).

Smart Pianist displays the Song screen with playback controls on the left-hand side of the screen. Touch “Tap here and select a Song” to drill down and find a song to analyze and play.

SP displays the Song Selection screen. For this example, an audio song, I tapped “Music Library” and navigated to the backing track for “It’s Too Late”. Tap the Done button to load and analyze the selected song (“It’s Too Late” by Carole King).

SP displays a score using the default accompaniment pattern, “Basic 1”.

Before discussing score patterns, let’s take a look at the chord chart. Tap the Chord button at the bottom of the screen. The backing track is in the key of A minor.

SP displays the chord chart containing the chords that it found and extracted during analysis. If you know Carole King’s music — and “It’s Too Late”, in particular — there are chord extensions (major sevenths and minor sevenths) everywhere. Smart Pianist (and Chord Tracker) does a good job with major and minor triads, but chord extensions and alternate bass notes, not so much. Fortunately, you can change an individual chord by tapping the chord in the chart and editing it.

The score is derived from the chord chart by applying a score accompaniment pattern. Tap the Score button at the bottom of the screen to return to the score. Tap the Song Settings button (icon) in the upper right corner of the screen.

Smart Pianist displays the Song Settings. Tap the Arrangement tab on the left side of the screen and go to the Accompaniment Score Pattern.

Smart Pianist displays a scrollable, drop-down list of the available accompaniment patterns. In this case, the pattern is “Basic 1”. Check out the diagram at the bottom of the screen. This diagram illustrates how the pattern will lay down notes in the right- and left-hand parts. “Basic 1” does simple block chords. Compare the diagram against the score.

Take a look at the three examples shown above. [Click to enlarge, of course.] The examples show how four simple “block” patterns affect the score display. The block patterns all produce block chords with simple left-hand bass notes.

Here are two more examples using arpeggio accompaniment patterns. Choosing new, different patterns is a way to get some practice and to try different keyboard arrangements.

List of all accompaniment patterns

Smart Pianist provides forty accompaniment score patterns:

  • Even – Block [Chords]
    • Basic 1 – 4
    • 8Beat 1 – 3
    • 16Beat 1 – 2
    • Pop Rock, Disco Twist, Ska
    • Beguin, Bossa, Samba, March
  • Even – Arpeggio [Broken Chords]
    • Easy Arpeggio 1 – 4
    • 8Beat Arpeggio 1 – 3
  • Even – Combination
    • Easy Pop 1 – 2
    • 8Beat Pop 1 – 2
  • Triplet – Block [Chords]
    • 8Beat Triplet 1 – 2
    • Triplet Ballade
    • Jazz 1 – 3
    • Blues
    • March Triplet
  • Triplet – Arpeggio [Broken Chords]
    • Slow Rock 1 – 2
  • Triplet – Combination
    • Swing Jazz
    • Slow Jazz

“Even” means straight time and “triplet” means triplet time division.

That’s a lot of screens and diagrams to browse through. In order to save both of us time, I gathered all of the pattern diagrams together (below). Enjoy!

Smart Pianist, CSP and ChordPro

Posted on by

Yamaha repurposes hardware and software technology all the time. The Yamaha CSP series digital pianos (CSP-100 series and CSP-200 series) and Smart Pianist borrow a lot of technology from the Yamaha Genos and PSR arrangers. Yamaha Chord Tracker users know that Smart Pianist also has Chord Tracker technology inside.

Chord Tracker provides a number of Smart Pianist-like features. Chord Tracker analyzes an audio song, extracts its chords, and displays the chords in a chart. Like Smart Pianist, Chord Tracker follows the chord chart while playing back the original audio file. Pretty much anyone can use Chord Tracker in this way to figure out the chords to a song and play along.

Genos and PSR arranger people, however, get extra goodies. Chord Tracker can send the chords to the arranger for playback. Even better, you get to choose the accompaniment style. Want to re-imagine a song as a country tune? You can do it.

Extended ChordPro

Chord Tracker sends the chords to an arranger in a Standard MIDI File (SMF). Instead of notes, the chords are represented in Yamaha System Exclusive MIDI messages.

When I analyzed the file format and chord messages, my first thought was “ChordPro”!

You’ve probably seen ChordPro on the Interwebs. It’s that simple text format for song lyrics and chords. I extended ChordPro adding a few new features to make musical time explicit and precise. (Original ChordPro relies on the musician for time.) Then I wrote a Java program to translate an Extended ChordPro song to an SMF suitable for playback on a Yamaha arranger. Check out an Extended ChordPro demo.

Playback ChordPro Example

Well, guess what? Smart Pianist and CSP-170 can play back SMFs generated from Extended ChordPro songs.

Here is a short ChordPro snippet for Steve Winwood’s “Can’t Find My Way Home”.

{t: Can't Find My Way Home}
{key: D}
{artist:Blind Faith}
{time: 4/4}
# Style: SongwriterBallad (stylecode: 5980)
{stylecode: 5980}
{tempo: 96}

{start_accomp}

# Introduction
[C][*IA]
{c: Introduction}
[Csus2:2][*MB] ---- [G/B:2] ---- [Gm/Bb:2] ---- [D/A:2] ---- 
[F:2] ---- [G:2] ---- [D] --------
[Csus2:2] ---- [G/B:2] ---- [Gm/Bb:2] ---- [D/A:2] ---- 
[F:2] ---- [G:2] ---- [D][*FB] --------

{c: Verse 1}
Come [Csus2:2][*MB] down off your [G/B:2] throne, and 
[Gm/Bb:2] leave your body a- [D/A:2] -lone.
[F:2] Some- [G:2] -body must [D] change.
[Csus2:2] You are the rea- [G/B:2] -son, I've been
[Gm/Bb:2] waiting so [D/A:2] long.
[F:2] Some- [G:2] -body holds the [D][*FC] key.

An Extended ChordPro song begins with a header containing the title, artist, key, tempo, time signature and auto-accompaniment style. After the header, you hit the {start_accomp} directive which tells the arranger (Genos, PSR or CSP) to start playing.

The rest of the Extended ChordPro file consists of chords, e.g., 

    [C]   [Csus2:2]   [G/B:2]   [Gm/Bb:2] ...

section control directives, e.g.,

    [*IA]  [*MB]   [*FC] ...

and lyrics (plain text). Oh, yeah, you can throw in comments, too, e.g.,

    {c: Introduction}
    {c: Verse 1}

The Java program (cp2mid) translates the chords, directives and lyrics into an arranger-ready Standard MIDI File.

So, what do we get after we import the SMF into Smart Pianist? The screenshot above [click to enlarge] is the score. The chord symbols and lyrics appear with the staves. There aren’t any notes because the SMF doesn’t have any notes; it’s contains only chords and lyrics.

The chord chart looks familiar. But, hey! Smart Pianist display lyrics interspersed with chords. I never saw Chord Tracker do that.

The final screenshot shows the lyrics alone. All of those dashes (“—-“) come from the Extended ChordPro song. They are placeholders during instrumental interludes.

Summary

Today’s example demonstrates a different way to use Smart Pianist and CSP digital pianos. If you own both a Yamaha arranger workstation and a CSP, you should be able to transfer Chord Tracker SMFs to Smart Pianist and the CSP.

Smart Pianist: MIDI song tutorial

Posted on by

I have an extensive collection of MIDI songs that are tweaked for the PSR-S950 and Genos (gen 1) arranger workstations. Let’s see what Yamaha Smart Pianist does with them!

Transfer the MIDI files

The first step is transferring the MIDI files from Windows PC to my iPad. I gathered about 100 Standard MIDI Files (SMF) into a directory, “MIDI”, with three subdirectories:

  • GM: General MIDI and General MIDI 2
  • S950: XG files tweaked for the PSR-S950
  • Yamaha: XG files purchased from Yamaha Musicsoft

The subdirectories reflect different vintages and format. I went with PSR-S950 because its voices are a subset of the CSP-170 voices. GM, GM2 and XG are compatible with CSP-170. Depending upon source and phase of the moon, a MIDI file may or may not have chord and lyric data. The XG files from Yamaha Musicsoft are more likely to have chords and lyrics (so-called XF format), but that is not a slam dunk. [Click on images to enlarge them.]

iTunes File Sharing seemed like the fastest way to move 100+ files. Unfortunately, no joy. iTunes found the Smart Pianist storage area without problem with four subdirectories under “Smart Pianist Documents”:

  • demo_audio
  • user_audio
  • user_midi
  • user_pdf

I tried to copy MIDI files into “user_midi” directly. Nope, iTunes won’t do it. The best I could do is to add files to the top-level “Smart Pianist Documents” directory.

That just didn’t seem right. So, I e-mailed a ZIP file containing the MIDI files to myself and downloaded the ZIP into the Files folder on the iPad. I tried to import the ZIP into Smart Pianist directly. It unzipped OK, but Smart Pianist expects to see one or MIDI files, not subdirectories! No joy, again.

Oh, dear. There isn’t any way to organize the MIDI files into folders (or categories) inside Smart Pianist. A linear list of 100+ MIDI files is not convenient or scalable. C’mon, Yamaha, you can do better.

Fortunately, Smart Pianist’s import dialog has a “Select All” option — if you can find it. I had to select the first file and scroll to the bottom of the list of files to find the “Select All” button. Might be a good idea to display “Select All” at the top of the dialog box like right away?

Well, after all this futzing around, I got all 100+ MIDI files imported into Smart Pianist.

Score, chords and lyrics

When you select a MIDI song, Smart Pianist looks for three kinds of data in the MIDI file: score (e.g., tracks with notes in them), chords and lyrics. Three buttons at the bottom of the screen let you select one of these three views during playback.

Smart Pianist displays some kind of score, typically the melody track, maybe a left-hand bass track. If Smart Pianist can’t make sense of the MIDI, it displays empty measures (e.g., whole note rests).

Chords and lyrics are optional in MIDI files and your mileage will vary. Smart Pianist will display chords and lyrics, if the relevant MIDI data are available.

How did Smart Pianist do?

No, I didn’t test 100 MIDI songs. 🙂 I chose four songs for testing:

  • Brown-Eyed Girl by Van Morrison
  • Every Little Thing by The Police
  • Let’s Stay Together by Al Green
  • I Wouldn’t Want To Be Like You by Alan Parsons

Brown-Eyed Girl, Every Little Thing and Let’s Stay Together are XG MIDI songs purchased from Yamaha. Most likely, they should have chord and lyric data (XF format). I Wouldn’t Want To Be Like You started life as a TUNE 1000 Karaoke General MIDI file and it contains lyrics.

In the case of Brown-Eyed Girl, Smart Pianist generated a score which looks like a combination of a bass line and the opening guitar riffs.

No chords were found, so you don’t get anything useful on the Chords page. I improvised the chords from the score when playing along. Then again, I have a good working knowledge of musical harmony. A beginner or inexperienced player would be lost.

The Brown-Eyed Girl MIDI file has embedded lyrics. Here’s the problem, tho’. What if I want to sing the lyrics and play a piano part? I can’t do it because, in Smart Pianist, by default, you get the piano score or the lyrics, not both at the same time. [We’ll remedy that in a few minutes. Please keep reading.]

Next up, Every Little Thing She Does Is Magic. Smart Pianist displays some form of score.

And it displays chords, too. I found the chord display to be the most helpful and I played along with the song ny following the Chord page. Not bad. If you are a Chord Tracker user, you’ll recognize the chord chart structure and format.

No lyrics were found in Every Little Thing, so you’re on your own. Maybe invite Sting over to sing. 🙂

Smart Pianist produced a score for Let’s Stay Together. Looks like the melody line to me.

The Let’s Stay Together MIDI file has chord data and Smart Pianist displays chords. No lyrics, tho’, so the Lyrics page is empty.

Smart Pianist displays a score for I Wouldn’t Want To Be Like You. It looks like the melody part, so the first N measures are blank during the instrumental introduction. Play by ear and fool around on a Cm7 scale…

Smart Pianist didn’t find chord data — no surprise as GM doesn’t support chord meta-events. You do get lyrics. TUNE 1000 was good with lyrics. It’s a shame TUNE 1000 as a company died over 15 years ago.

Smart Pianist displays what it can and you can have fun with it. Still, you may feel disappointed. Let’s try to make things better.

Song Settings

Up to this point in the tour, we Smart Pianist’s default Song Settings and went with them. Yamaha borrowed many ideas and features from its arranger workstations. Song Settings are the gateway to those features.

I want to display lyrics on the Score. Tap the Song Settings icon in the upper right-hand corner of the screen. Then tap “Score” to select the Score Settings page.

The Score Settings page has six settings:

  • Choose the score display size: Small, Medium or Large.
  • Display the Left- and/or Right-hand parts
  • Display the Right-hand part on a grand staff (treble plus bass clef)
  • Display chords in the Score
  • Display lyrics in the Score
  • Set note quantization (granularity of the time grid)

The I Wouldn’t Want To Be Like You MIDI file doesn’t have chord data, so I left Chord disabled. I turned Lyrics on. I tried turning a Left-hand part on, but Smart Pianist wouldn’t let me. [More about that in a second.]

The screen grab above shows the result. Smart Pianist displays the Score and, behold, lyrics appear below the melody line!

Instead of the melody, I really want to play chords and comp along with the song. In order to find a MIDI song track with the kind of part that I want to play, I opened the (MIDI) Mixer tab in the Song Settings.

The MIDI Mixer shows the instrument type which is assigned to each MIDI channel. (A MIDI song may have up to 16 channels.) Channel 1 has an electric piano (EP) which plays during the entire song. Channel 2 has a fretless bass. These MIDI channels are good candidates for the score.

While we’re on the MIDI Mixer page, please note that you can set the volume, pan and reverb send for each instrumental part (channel). The Master knobs and slider set the overall pan, reverb send and volume level for the MIDI song. You can use the MIDI Mixer to re-mix the backing song!

Now select the Song Settings Playback tab. Here you can turn the Stream Lights on and off, set the Stream Lights speed, etc.

Check out the MIDI Part Channel settings at the bottom of the page. By default, Auto Set is turned on. This instructs Smart Pianist to find appropriate MIDI channels to display in the score. Notice that Right is set to MIDI channel 4 and Left is off. A-ha! That’s why we saw the melody part (channel 4) in the score and why the Left-hand part is disabled.

Some inside baseball — TUNE 1000 the company is defunct, but their lasting contribution is the Karaoke (KAR) MIDI file format. Channel 4 in karaoke-land is the melody channel.

Turn off Auto Set.

Next, set the Right MIDI channel to 1 (the electric piano) and set the Left MIDI channel to 2 (the fretless bass). Tap the Done button to return to the Score display.

Voila! The Score shows the electric piano part in the upper staff and the fretless bass part in the lower staff. And, the Score still has the lyrics. This is just what I wanted.

I don’t blame you if you feel a little tired after menu diving. You wouldn’t want to do that every time. That’s where Smart Pianist registrations come to the rescue. Tap the Registration icon in the lower left corner of the screen.

Smart Pianist pops up a dialog box asking for the name of the new Registration to be saved. Enter the name (I_Wouldnt_Want_To_Be) and tap the Save button. Smart Pianist saves all of the Song Settings. So the next time you want to play this song, just recall the Registration.

Here’s a bonus! I changed to a different MIDI song: I Played The Fool (by Southside Johnny and the Asbury Jukes). Smart Pianist applied the same, existing Song Settings and, by dumb luck, it displayed a nice right-hand part for comping, the bass line in the left-hand, and the lyrics. How good is that?

Well, I hope that you learned some new Smart Pianist tricks. Don’t be afraid to dive into the Song Settings and tweak the Score to your liking.

The quest for Backing Conductor

Posted on by

Yamaha released a new version of the Smart Pianist app. The release notes list three new features:

  • Backing Conductor (CSP Series, CVP Series and P-S500 only)
  • A-B Repeat for PDF scores
  • Scores for the 50 Classics are distributed and displayed via PDF

The Backing Conductor sounded intriguing and I was anxious to jump on it right away.

I noticed that the CSP Series 200 models require a Firmware Update for Backing Conductor. Be sure to check the downloads page for your CSP.

The Apple App store pushed version 3.6.0 to my iPad. No problem there. The screen shot (above) shows Smart Pianist 3.6.0 (January 15, 2025) running and firmware 1.09a installed on the CSP-170. Hopefully, firmware version 1.09a is good because Yamaha never stated if an update is required for the CSP 100 series.

What is Backing Conductor?

The big question: “What is Smart Pianist Backing Conductor?” At this point in time, Yamaha have not publicized any additional information. The Smart Pianist guide, such as it is, has not been updated.

Yamaha software engineering believes that they design intuitive user interfaces (apparently). No documentation required! Quite frankly, if one of my CS students made such a statement, they would have been corrected and marked down. Seriously. 🙁

And so began my quest for “Backing Conductor.”

Post-install splash screens

At one point in my quest, I deleted the Smart Pianist app and re-installed it. Below are two rather informative post-install screens which highlight Smart Pianist’s capabilities.

Blink or idly flip by and you will miss these highlights. Forever — they won’t be repeated.

Yamaha should distribute the example score “New York Hustle”. It appears in other examples. By the way, “Hustle” is misspelled as “Hastle” in the second splash screen. Sorry, I live with a professional editor…

Start-up splash screens

Every time you start up Smart Pianist and connect to your instrument, you will be treated to a different splash screen. Again, don’t blink because you will miss something.

Here are three of the screens which highlight new features in version 3.6.0. Yeah, I know. What are they and how do I use them?

“Backing Conductor” gets mentioned again without details.

Backing Conductor, finally

Finally, I hit on the fourth of these elusive splash screens (below).

Oh, now I see what I should look for!

When a PDF is displayed, Smart Pianist displays this playback control box at the top. Folks who have used earlier versions of Smart Pianist recognize the three part buttons: Others, Left and Right. Backing Conductor adds a new part button: Backing. I guess when Backing is turned ON, you can change the auto-accompaniment style, in this case, Cool 8Beat.

There’s “New York Hustle” and “Hastle”, again.

Taco Bell’s Cannon

Now that I have a clue, let’s try a PDF score: Canon D dur by Pachelbel.

Uh, oh. The Backing button and accompaniment style are greyed out. What gives? In this case, Smart Pianist plays back the PDF score without backing.

One of my big frustration using Smart Pianist is what appears to be inconsistent behavior and options. There must be rules governing behavior and user operations. The rules probably differ by the content/media type:

  • PDF score (PDF file)
  • MIDI song (Standard MIDI File)
  • Audio song (MP3, AAC, etc.)
  • Chords extracted from an audio song

I wish Yamaha would explicitly write down the dos and don’ts for each data type. Explicit rules would set expectations straight and reduce frustration.

Bonus screen

To round things out, here is the Song Settings Arrangement screen for Audio to Score playback.

In this screen, you can choose the accompaniment score pattern to be used when displaying the extracted score and you can choose the backing style. I like the ability to turn different backing parts off (on) individually. Sometimes ya just want a beat, sometimes a beat plus bass, and sometimes a full backing.

Summary

I hope my difficulties have not discouraged you. Maybe you’ll be a little bit smarter then I when you sit down with Smart Pianist.

Before ending, I want to mention my top Smart Pianist want: the ability to add new styles to Smart Pianist. I’m not asking for Style Creator as one finds in the arranger workstations — simply the ability to load new styles and play new backing styles. There are so many user-contributed styles (including my own!), the ability to load and play with new styles would give CSP a huge boost.

NAMM 2025: Wait, there’s more!

Posted on by

Hope you’ve caught your breath. This year’s NAMM (2025) has brought a bumper crop of new keyboard releases.

Just to list a few that we’ve seen. This is an exciting year for players!

Nord Piano 6

Check your credit limit because Nord weren’t finished after announcing the Nord Organ 3. Today, Nord have given us the Nord Piano 6:

  • Dual layers for piano and synth with independent effects
  • Dedicated LED faders for each layer
  • Triple sensor keybed
  • Nord triple pedal 2 is included
  • New spring reverb and spin effects

Two piano layers plus two synth layers will give punters better splits and layers over previous models, addressing a frequently voiced need.

Nord Piano 6 73

Catch the introductory video. Sure sounds nice. The Bonners video hits the highlights.

There will be two models:

  • Nord Piano 6 88, 88-key triple sensor keybed with grand weighted action, 19.2 kg (42.3 lbs)
  • Nord Piano 6 73, 73-key triple sensor keybed with grand weighted action, 16.2 kg (35.7 lbs)

The 73 is priced at $3,599 USD (£2,999) and the 88 is priced at $3,799 (£3,299).

Viscount Legend One

Viscount International have released new videos demonstrating the new Viscount Legend One stage keyboard. Here are a few links to start you off:

Kraft Music have a short page about the Legend One. The 61 and 73 are available for pre-order at $1,790 USD and $1,990, respectively. Now those are competitive prices!

Ketron (AjamSonic)

Ketron is not a well-known name in North America. However, they offer a range of digital pianos, arranger keyboards and modules. They are represented in the United States by AjamSonic.

AjamSonic (Ketron) will have a booth at NAMM 2025 next week. (Jeez, we’ve seen all this stuff and the show hasn’t started!) Here is a video from AjamSonic, including a preview of their NAMM announcements.

  • EVENT flagship arranger workstation
  • EVP 1 flagship grand piano
  • EVP 2 upright/spinet digital piano
  • EVP 4 stage/slab piano
  • EVS pocket-sized professional sound module
  • FUSION multi-cultural (world) arranger and production keyboard
    • EVENT functionality and features
    • Real arranger and multi-ethnic styles
    • Joystick, ribbon, articulations and drum pad
    • 4GByte user flash memory (2GB Sbk and 2GB sampler)
    • Oriental drum kits, sounds and musical scale
  • New sounds, new styles
  • KB series near-field powered speakers (KB5A and KB6A)
  • KS10A active sub woofer
  • KM6 portable mixer

The AjamSonic video is refreshingly mellow. Chill.

Ketron EVS sound module

The EVS caught my eye because I am always looking for new sound modules. Features include:

  • EVENT sound engine in a small box
  • 256 factory presets
  • 256 user presets
  • Ability to layer three voices
  • Desk-top voice ditor
  • USB and MIDI IN/OUT

It can be used as a MIDI file player as well as an external sound module.

You can try the Ketron America link, but Chrome gives me guff.

More Yamaha updates

Yamaha snuck out a small update for the Montage M series. They also released Smart Pianist v3.6.0 with “Backing Conductor”. I’m currently trying v3.6.0 and searching for Backing Conductor within. One question has already gone out to Yamaha customer support — what the heck is Backing Conductor?

[Update] CSP-200 series models need a firmware update to enable Backing Conductor. The Smart Pianist specification PDF shows Backing Conductor to be supported on CSP-100 series and P-S500. I didn’t find a CSP-100 series firmware update, so maybe Yamaha has not yet pushed the update file?
