​Major Similarities Between Casio CTK 3500 VS Casio CTX 700

An obvious similarity between the Casio CTK 3500 and the CTX 700 is that both of them are 61-key touch-sensitive keyboards.  This quality ensures enhanced musical expression, similar to an acoustic piano. On these keyboards, the harder you press the keys, the louder the sound is produced. This gives the player a chance to take control of the keyboard and create music as they please.

Another feature common to the CTK 3500 and CTX 700 is the number of polyphony they have. Both of them have 48 notes of polyphonies, which allow you to play several individual melodies simultaneously.

The digital pianos also provide MIDI connection via USB to Host. This lets you connect your keyboard with MIDI (Musical Instrument Digital Interface) ports to any external device (PC, android phone, iPhone, etc.). Because of this connectivity option, you can transfer and share your music pieces for instant feedback or changes. This makes the whole process of connecting the piano to your computer (or any other electronic device) a lot easier.

The CTK 3500 and CTX 700 also come with a sustain pedal input. So, you won’t have to buy it separately and will save your money, too. With this element, your music will sound more in-tuned. The pitch sound will vibrate until the pedal remains pressed.

The keyboards also incorporate metronome and transposition, which are important tools in music. A metronome is a learning tool that creates steady beats, allowing musicians to play rhythms perfectly.  On the other hand, a transposition lets you produce a variety of notes up or down with a continuous interval.

Casio CTK 3500 and the CTX 700 operate with batteries, allowing you to play them at any part of the house. You can use these digital pianos outdoor as well. Since both of them are compact and lightweight, you can carry them with you anywhere you like.  The piano models do not pose any travel restriction, making it an ideal travel companion.

​Major Differences Between Casio CTK 3500 VS Casio CTX 700

The CTK 3500 is a basic keyboard than the CTX 700. The former has fewer number of sounds and rhythms. For instance, the CTK 3500 has 400 tones, while the CTX 700 has 600 of them. When it comes to rhythms, the CTK 700 has 195 of them, while the CTK 3500 contains only 46 along with 100 built-in rhythms.

Casio CTK 3500 has a variety of educational features such as Lesson Lite, Scoring System, and Voice Fingering Guide. Other than this, there is also a lesson for learning the piano using the left hand, right hand, and both hands. These features make the CTK 3500 perfect for beginners. However, the educational feature is absent from the Casio CTX 700. As we said, the CTX 700 is not an entry-level piano like the CTK 3500.

This allows you to play one chord at a time rather than letting you play all of the notes simultaneously. This key feature is missing in the CTK 3500.

Also, Casio CTX 700 offers an output line connection, which means it has additional power to connect to loud sound equipment.  With the CTK 3500, you get a pitch bend wheel, but it’s not present with the CTX 700.  The latter also has more powerful speakers (5W) and amplifiers (4.7” x 2) as compared to the speakers (2W + 2W) and amplifiers (3.9” x 2) of the Casio CTK 3500.
