Your Keyboard Guide: Casio CT-X9000IN

The Only Guide You Need for Your First 20 Hours

Section titled “The Only Guide You Need for Your First 20 Hours”

Your CT-X9000IN has 800 tones, 250 rhythms, a built-in lesson system, a MIDI recorder, and about 200 buttons. You do not need 90% of that right now. This guide covers exactly what matters for your first 20 hours of learning — nothing more, nothing less.

Keep this guide next to your keyboard. Come back to it whenever you need to find a feature.


You have never used an electronic keyboard before. Here is exactly what to do, step by step.

  • Your CT-X9000IN keyboard
  • The AC adapter that came in the box (labeled AD-E95100L or similar)
  • A flat, stable surface — a table or keyboard stand at a height where your forearms are roughly parallel to the floor when seated
  • A chair or bench (no armrests — they get in the way)
  1. Place the keyboard on your table or stand. The longer side faces you. The lower-pitched (deeper sounding) keys are on your left; higher-pitched keys are on your right.
  2. Connect the AC adapter. Find the DC port on the back of the keyboard (labeled DC 9.5V). Plug the adapter cable in, then plug the adapter into a wall outlet. Always use the AC adapter for regular practice — batteries drain quickly.
  3. Turn it on. Press the POWER button (marked with a power symbol, top-left of the panel). The display screen will light up.
  4. Set the volume. Turn the VOLUME knob (near the top-left, next to the power button) to about the halfway position. You can always adjust later.
  5. Play a key. Press any white key. You should hear a Grand Piano sound — this is the default tone when you power on. Congratulations, you just played your first note.
SituationWhat to Do
Auto Power OffThe keyboard automatically turns off after 30 minutes of no activity. To disable this, hold the FUNCTION button, navigate to “Auto Power Off,” and set it to “Off.” But for now, don’t worry about it — just turn it back on if it shuts off.
No soundCheck that the volume is turned up, the AC adapter is firmly connected, and the speakers are not muted. Make sure headphones are not plugged in (the headphone jack is on the back — if something is plugged in there, sound goes to headphones only).

Try This Now: Turn on the keyboard, set volume to halfway, and press 5 different white keys from left to right. Notice how the sound goes from low to high. That is the basic layout of every keyboard in the world — low on the left, high on the right.


You have a lot of buttons in front of you. For Week 1, you only need to know these:

ControlWhere It IsWhat It Does
POWERTop-left cornerTurns keyboard on/off
VOLUMEKnob, top-left areaControls how loud the sound is
TONETop panel, labeled “TONE”Switches to tone selection mode — lets you pick different instrument sounds
RHYTHMTop panel, near TONESwitches to rhythm selection mode — lets you pick drum/accompaniment patterns
CATEGORYTop panel, near displayCycles through tone or rhythm categories (Piano, Organ, Strings, etc.)
Dial (Jog Dial)Circular dial near the displayScrolls through tones, rhythms, or menu options. Turn it like a volume knob
Number Keys (0-9)Top panel, arranged like a phone keypadType in a tone or rhythm number directly if you know it
TEMPO +/-Two buttons near the displaySpeed up or slow down the metronome or rhythm
START/STOPTop panel, prominent buttonStarts or stops a rhythm pattern
  1. Press the TONE button. The display shows the current tone name and number.
  2. Use the CATEGORY button to jump between tone families: Piano, Electric Piano, Organ, Guitar, Strings, and so on. Each press moves to the next category.
  3. Use the Dial to scroll through individual tones within a category.
  4. Alternatively, use the Number Keys to type a tone number directly (if you know it).
  5. Play a key to hear the new sound immediately.
  1. Press the RHYTHM button. The display shows the current rhythm name and number.
  2. Use the CATEGORY button to browse rhythm families: 8-Beat, 16-Beat, Ballad, Dance, Indian, and so on.
  3. Use the Dial to scroll through rhythms within a category.
  4. Press START/STOP to hear the rhythm play.

Try This Now: Press TONE, then press CATEGORY a few times. Notice the display changing between Piano, E.Piano, Organ, Guitar, etc. Use the Dial to scroll through a few sounds within any category. Press a key each time to hear the difference. Spend 2 minutes just exploring — there is no wrong answer here.


Your keyboard has 800 tones. For learning piano, you need exactly one: Grand Piano. Here are a few others for variety.

ToneTone NumberCategoryWhen to UseHow to Find It
Grand Piano000PianoAll practice, all the time. This is your default.Press TONE, type 000 with the number keys — or press CATEGORY until you see “Piano.” It is the first tone. The keyboard loads this automatically at startup.
Bright Piano001PianoWhen you want a crisper, more present soundSame category as Grand Piano — scroll with the Dial one click forward, or type 001
Electric Piano026E.PianoFun variety, great for pop songsPress CATEGORY until you see “E.Piano,” or type 026
Church Organ060OrganPlaying hymns or sustained pieces — notes hold at full volume regardless of touchPress CATEGORY until you see “Organ,” or type 060
Strings049StringsHearing how a melody sounds with an orchestral feelPress CATEGORY until you see “Strings,” or type 049
HarpsichordVarious/KeyboardBaroque pieces, or just a fun change — very distinct plucky soundBrowse the Organ or miscellaneous keyboard category with the Dial

Practice on Grand Piano. It responds to how hard you press (touch response), which teaches you dynamics — the foundation of expressive playing. Switch to other tones for fun, but always come back to Grand Piano for serious work.

Try This Now: Find Grand Piano (it should already be selected when you turn on). Play “C-D-E-F-G” (the five white keys starting from the white key just left of a group of two black keys). Now switch to Electric Piano and play the same five notes. Hear the difference? Try Strings. Try Organ. Then switch back to Grand Piano. That is your home base.


A metronome is a steady click that helps you play in time. It is the single most important practice tool on your keyboard.

  1. Press the METRONOME button (located on the top panel, near the TEMPO controls). The display will show the beat count.
  2. Press METRONOME again to stop it.
  3. Use the TEMPO + and TEMPO - buttons to change the speed. The number on the display is BPM (beats per minute). Higher number = faster.
  4. Some Casio models include a TAP TEMPO feature — check your keyboard’s controls. If available, tap it 4 times at the speed you want to set a tempo by feel.

The metronome can click in different time signatures:

  • 4 beats per measure (the standard): counted as “1-2-3-4, 1-2-3-4.” You will use this most of the time.
  • 3 beats per measure (waltz time): counted as “1-2-3, 1-2-3.” Used for waltzes.

Access the beat setting through the FUNCTION menu: press FUNCTION, navigate to “Metronome” > “Beat,” and set it to 4 (for 4/4 time) or 3 (for 3/4 time).

ActivityBPMWhy
Slow scale practice50-60Gives you time to think about each note
Moderate practice70-80Good for simple songs once you know the notes
Comfortable playing90-100Where most beginner pieces should eventually land

Playing without a metronome is like running without a watch — you have no idea if you are going the right speed. The metronome teaches your body to feel steady time, which is the foundation of all music. It will feel annoying at first. That is normal. Use it anyway.

Try This Now: Turn on the metronome. Set it to 60 BPM (one click per second). Find Middle C on your keyboard (the C nearest to the center — just left of a group of two black keys, roughly in the middle). Press C once on every click. Just C, over and over, perfectly in time. Do this for 30 seconds. Harder than it sounds, right? That is the metronome doing its job.


Your CT-X9000IN has a built-in lesson system with pre-loaded songs you can learn step by step. Think of it as a mini-teacher inside your keyboard.

  1. Press the SONG BANK button. The display shows available built-in songs.
  2. Use the Dial or Number Keys to select a song.
  3. Press the STEP-UP LESSON button (or the corresponding lesson button on the panel) to enter lesson mode.
ModeWhat HappensWhen to Use
ListenThe keyboard plays the song for you. Just listen and watch the display.First time hearing a new song. Get familiar with how it should sound.
WatchThe keyboard plays slowly and the display shows which keys to press. You watch, but do not play yet.Second pass — observe the fingering and rhythm before trying.
Remember (Play)The keyboard waits for you to press the correct key before moving on. It will not continue until you play the right note.Now you play along. The keyboard is infinitely patient — it waits for you.
  • Right Hand only: Learn the melody part
  • Left Hand only: Learn the accompaniment/bass part
  • Both Hands: Put it all together

The Step-Up Lessons are supplementary to your main course sessions. Use them as bonus homework — they give you extra songs to practice and reinforce note reading and rhythm skills. Your course sessions are your primary learning path; the Step-Up Lessons are extra credit.

Try This Now: Press SONG BANK and scroll through the available songs with the Dial. Pick any song. Press the lesson button and select “Listen” mode. Just sit back and listen to the keyboard play. Then try “Watch” mode. When you feel ready, try “Remember” mode for the right hand — the keyboard will wait for you to find each note. No pressure, no timer.


Your keyboard has a built-in 16-track MIDI recorder. This is one of the most powerful learning tools you have — and most beginners never use it.

  • Self-review: Record yourself, play it back, hear your mistakes. You notice things in playback that you miss while playing.
  • Practice hands separately: Record your left hand part, play it back, and practice your right hand on top of the playback. This is introduced in Session 5 of your course and is a game-changer for learning two-hand coordination.
  • Track progress: Record the same piece every few weeks. Compare your Week 1 recording to your Week 10 recording. You will be amazed.
  1. Press the RECORD/STOP button. The display will show the recording screen.
  2. Select which track to record on (Track 1 is fine for most purposes). Use the Dial to choose.
  3. Press RECORD/STOP again (or press START/STOP) to begin recording. A pre-count may play to give you a tempo reference.
  4. Play your piece.
  5. Press RECORD/STOP when finished. Your performance is saved.
  1. Press PLAY/STOP (or START/STOP, depending on the mode). Your recording plays back through the speakers.
  2. Press PLAY/STOP again to stop playback.
  1. After recording Track 1 (say, your left hand), press RECORD/STOP again.
  2. Select Track 2.
  3. Press record. Track 1 plays back while you record Track 2 (your right hand) on top.
  4. Press stop. Now both tracks play together.

This is exactly how you will practice in Session 5: record LH on Track 1, then practice RH on Track 2 while listening to your LH playback.

Access the recording menu, select the song/track you want to clear, and choose the delete option. Refer to the display prompts — the keyboard walks you through it.

Try This Now: Press RECORD/STOP. Select Track 1. Press record, then play C-D-E-F-G slowly with your right hand. Press stop. Now press PLAY/STOP and listen to yourself. Weird hearing yourself played back? Good — that is the point. Now you know how to record.


Touch response means the keyboard senses how hard you press a key. Press gently, it sounds soft. Press firmly, it sounds loud. This is how a real acoustic piano behaves, and it is essential for musical expression.

Imagine typing on a regular computer keyboard — every keystroke makes the same sound regardless of how hard you press. Now imagine if typing harder made LOUDER letters. That is touch response. Your keyboard can sense the difference between a gentle tap and a firm press, and it changes the volume accordingly.

The CT-X9000IN has a Touch Response setting accessible through the FUNCTION menu:

  1. Press the FUNCTION button.
  2. Navigate to “Touch Response” (use the CATEGORY or Dial to find it).
  3. You will see the following options:
SettingWhat It Does
OffEvery key press sounds the same volume, no matter how hard you press
LightSmall differences between soft and hard — more forgiving for beginners
NormalStandard sensitivity — recommended for most practice
HeavyYou need to press quite hard for loud sounds — builds finger strength
SettingWhen to Use
Normal (ON)Most of the time. This is how you learn dynamics and musical expression. Keep it here for 90% of your practice.
OffWhen you are doing pure finger exercises and want consistent volume — for example, scale drills where you are focusing only on even timing.
LightIf Normal feels too sensitive and your dynamics are unintentionally all over the place. Good for the first few sessions.
HeavyWhen you want to build finger strength. Not recommended until you are comfortable with the basics.

Try This Now: Make sure touch response is set to Normal. Place your right thumb on Middle C. Press the key as gently as possible — barely touching it. Listen to the soft sound. Now press the same key firmly (not slamming — just a confident press). Hear the difference? Now play C-D-E-F-G, alternating soft-loud-soft-loud-soft. You are already learning dynamics, and that is what makes music sound like music, not just notes.


Your CT-X9000IN can play drum patterns and bass/chord accompaniment automatically while you play melody on top. Think of it as having a band backing you up.

  1. Press the RHYTHM button.
  2. Use CATEGORY to browse rhythm families (8 Beat, 16 Beat, Ballad, Waltz, Latin, Indian, etc.).
  3. Use the Dial to scroll through rhythms within the category.
  4. Press START/STOP to hear the rhythm.
  5. Use TEMPO +/- to adjust the speed.

When auto-accompaniment is active, the left side of the keyboard (below the split point) becomes a chord input zone:

  1. Turn on accompaniment mode (press ACCOMP or the relevant mode button — the display will indicate when accompaniment is active).
  2. Start a rhythm with START/STOP.
  3. Play a chord with your left hand in the lower section of the keyboard. The keyboard automatically adds bass, drums, and harmony based on the chord you play.
  4. Play melody with your right hand in the upper section.

For example: play a C major chord (C-E-G) with your left hand, and the keyboard fills in a full band accompaniment in the key of C.

RhythmCategoryBPM RangeGood For
8 Beat 18 Beat80-100General pop song practice, steady and simple
16 Beat 116 Beat90-110Slightly busier feel, good for contemporary songs
WaltzBallroom90-1203/4 time practice (Session 8 onwards)
Ballad 1Ballad60-80Slow, expressive songs

Start simple. In Session 8, you will begin using rhythm accompaniment to practice chord changes. The rhythm keeps you honest about timing — if you change chords late, you will hear it immediately because the bass and drums have already moved on.

Try This Now: Press RHYTHM. Use CATEGORY to find “8 Beat.” Use the Dial to select “8 Beat 1” (or the first option). Set tempo to 80 BPM using TEMPO buttons. Press START/STOP. Hear that steady drum pattern? Now play a few notes with your right hand on top. Try pressing C-E-G together with your left hand (in the lower half of the keyboard) — the accompaniment should change to match. Press START/STOP to stop. You just jammed with a backing band.


Your keyboard has a USB to Host port on the back panel. This connects your keyboard to a computer, phone, or tablet for expanded learning options.

  • Sends and receives MIDI data (digital note information) between your keyboard and a device
  • Allows you to use piano learning apps that display notes on a screen as you play
  • Lets you use your keyboard as a MIDI controller with music software on a computer

Chordana Play is Casio’s free companion app (available for iOS and Android).

  1. Download “Chordana Play” from the App Store (iPhone/iPad) or Google Play Store (Android).
  2. Get a USB cable (Type B on the keyboard end, matching your phone/tablet on the other end). You may need a USB-B to USB-C adapter or a USB-B to Lightning adapter depending on your device.
  3. Plug the USB cable into the USB to Host port on the back of your keyboard.
  4. Plug the other end into your phone or tablet.
  5. Open Chordana Play. It should detect your keyboard automatically.
  • Visual keyboard display: See which keys to press on screen while you play
  • Song library: Load songs and see the notes scroll on screen in real-time
  • Score viewer: Display sheet music on your device
  • Interactive lessons: The app can guide you through songs step by step

Chordana Play is supplementary — it is not required for this course. Everything in your 20-hour course can be done with just the keyboard and the course materials. The app is a bonus if you want extra visual learning support or more songs to practice.

Try This Now: If you have a compatible USB cable, try connecting your keyboard to your phone and opening Chordana Play. Browse the song library. If you do not have the right cable yet, bookmark this section for later — it is not urgent.


This is where your CT-X9000IN truly stands apart. It comes loaded with 43 Indian tones and 39 Indian rhythms — an entire world of Indian musical instruments and patterns at your fingertips.

  1. Press the TONE button.
  2. Press CATEGORY repeatedly until you reach the Indian category (keep pressing — it is after the standard Western instrument categories).
  3. Use the Dial to scroll through the Indian tones.
ToneWhat It Sounds LikeTry This
SitarThe iconic plucked string sound of Indian classical musicPlay a slow ascending scale: C-D-E-F-G-A-B-C. The bends and resonance are authentic.
TanpuraA continuous drone — the backdrop of all Indian classical musicHold down a C note and let it ring. This sustained, meditative sound is meant to support other instruments.
HarmoniumThe pumped reed organ heard in bhajans, qawwali, and kirtansPlay a simple melody — C-D-E-C-D-E. The warm, breathy tone is immediately recognizable.
TablaPercussive hand drums — the rhythm backbone of Indian musicDifferent keys produce different tabla strokes (Na, Dha, Tin, etc.). Press various keys across the keyboard.
Santoor (Santur)A hammered string instrument from Kashmir — bright and shimmeringPlay quick ascending notes. The sparkling quality is distinctive.

DandiyaFast, rhythmicStick-dance rhythmNavratri, Gujarati folk

Your keyboard also includes special combination patterns like “Keharwa Tanpura & Tabla,” “Dadra Tanpura & Tabla,” and “Teen Taal Tanpura & Tabla” — these add a tanpura drone to the rhythm pattern for an authentic Indian classical practice environment.

  • Session 4: Try playing “Jana Gana Mana” (India’s national anthem) using the Sitar tone for a different perspective on the melody
  • Session 9: Play a Bollywood melody with an Indian rhythm accompaniment running
  • Session 13: “Tum Hi Ho” chord progression pairs beautifully with Indian Pop rhythms
  • Session 18: Choose an Indian piece for your repertoire workshop and explore Indian tones for performance
Try This Now: Press TONE, navigate to the Indian category, and find the Tanpura tone. Play Sa-Re-Ga-Ma (that is C-D-E-F on your keyboard). Hear how instantly "Indian" it sounds? The tone transforms familiar Western notes into something that feels like it belongs in a classical music concert. Now switch to the Sitar tone and play the same four notes. Completely different character, but equally Indian. Now press RHYTHM, find Keharwa in the Indian category, start it at 80 BPM, switch your tone back to Grand Piano, and play C-D-E-F-G over the rhythm. You are playing with a tabla and dholak backing you up.

Your CT-X9000IN is a well-built instrument, but a little care goes a long way.

  • Cover it when not in use. Dust is the enemy of electronics. Use the dust cover that came with your keyboard, or drape a clean cloth over it. This keeps dust out of the keys, the speakers, and the display.
  • Keep drinks away. Spilling liquid on an electronic keyboard can cause permanent damage. No chai, no water, no anything on or near the keyboard. Keep beverages on a separate table.
  • Keys: Wipe with a soft, dry cloth. If keys get sticky or grimy, use a slightly damp cloth (barely damp — not wet), then dry immediately. Never use alcohol, solvents, or chemical cleaners.
  • Body/Panel: Soft dry cloth only. The display screen can be gently wiped with a microfiber cloth.
  • Never spray anything directly on the keyboard. If you must use a cleaning solution, spray it on the cloth first, not on the instrument.
  • Your CT-X9000IN has powerful speakers (15W + 15W with bass reflex). Do not poke or press the speaker grilles.
  • Avoid playing at maximum volume for extended periods — it stresses the speakers and your ears.
  • Use the AC adapter for regular practice. It provides consistent power and saves you from buying batteries.
  • If you use batteries: The keyboard takes 6 AA batteries. Remove them if you are using the AC adapter long-term — batteries left inside can corrode over months and damage the battery compartment.
  • Unplug the AC adapter from the wall when not in use for extended periods (going on vacation, etc.). This prevents unnecessary power draw and protects against voltage spikes.
  • If you need to move the keyboard, carry it with both hands. It weighs about 7 kg — not extremely heavy, but awkward if held from one end.
  • Use the carry case (if you have one) for transport outside the home.
  • Never place heavy objects on top of the keyboard.
  • Avoid direct sunlight on the keyboard for long periods — it can fade the panel markings and overheat the electronics.
  • Keep it away from extreme heat or cold.
  • Avoid very humid environments — moisture and electronics do not mix.

Try This Now: Look at your keyboard setup right now. Is it on a stable surface? Is there a drink nearby that could spill? Do you have a cover or cloth ready for when you finish practicing? Set up good habits from Day 1 and your keyboard will last for years.
