Who it fits
Good fit for
This keyboard suits beginners and travelers who need a lightweight instrument. The foldable design and included carry bag make it ideal for students practicing at school or musicians on the go. The 88 semi-weighted keys provide enough resistance for fingering practice, bridging the gap between simple controllers and heavy acoustic pianos. If you need a portable option that connects to your computer for composition via MIDI, this model fits your workflow. It is also good for small apartments where storage space is limited.
Who should skip it
You should look elsewhere if you require fully weighted hammer action keys. This model uses semi-weighted keys, which do not replicate the heavy resistance of an acoustic piano. If you are an advanced classical pianist training for performance, the touch sensitivity may not be sufficient. Additionally, if you need Bluetooth connectivity, this unit only offers Micro USB MIDI. Players seeking a built-in display or extensive onboard sound library beyond 128 tones will find this basic feature set limiting.
Verdict: The Dellersound folding keyboard offers a unique portable solution for beginners and travelers. Its compact design and MIDI capabilities make it a practical choice for flexible practice sessions.
Key specs explained for this piano
Number of Keys: 88
This instrument includes the full set of keys found on an acoustic piano. You get standard black and white keys arranged in the usual pattern. This layout allows you to play complex classical pieces or jazz chords without any gaps. If you are learning proper technique, having all eighty-eight keys ensures you do not develop bad habits. It matches the standard configuration expected by most teachers and method books.
Key Action: Semi-weighted, touch-sensitive
The keys offer resistance that mimics a real piano, but they are lighter than fully weighted actions. This helps you build finger strength without causing fatigue during long practice sessions. Touch sensitivity means playing harder produces a louder sound. This feature adds expression to your performance. It is ideal for beginners who want realistic feedback without the heavy effort of professional stage pianos.
Connectivity: Micro USB, MIDI
You can connect the keyboard to computers or smartphones using a micro USB cable. The MIDI function lets you send musical data to digital audio workstations. This setup allows you to compose music using software instruments on your laptop. It bridges the gap between hardware and digital production. Check your device ports to ensure compatibility with the included cable type before purchasing.
Preset Sounds: 128 tones
The keyboard comes with one hundred and twenty-eight built-in instrument sounds. These include piano, organ, strings, and other common tones. You can switch between these sounds to explore different musical styles. This variety keeps practice sessions interesting for students. It provides enough options for basic songwriting and experimentation without needing external sound modules or expansions.
Form Factor: Portable
The design prioritizes easy transport and storage. You can fold the keyboard in half to reduce its footprint. This makes it suitable for taking to school, outdoor events, or small apartments. The included carry bag protects the unit during travel. If you have limited space or need to move your instrument frequently, this portable design offers significant convenience over traditional stationary digital pianos.
Design and Build Quality
According to the listing, this instrument features a unique folding form factor. The keyboard splits in half for storage. When folded, it measures 63 by 22 by 13 cm. This compact size allows you to place it in small spaces or carry it easily. The unit weighs 11 pounds (4 kg). This light weight supports portable use for travel or outdoor practice. The listing notes a wood finish, which adds a traditional aesthetic to the modern folding design. You can choose between black or red colors.
The key layout consists of 88 full-size standard keys. They are crafted with a 1:1 piano key ratio. The key action is described as semi-weighted and touch-sensitive. This setup aims to enhance fingering practice and provide a realistic touch response. It bridges the gap between lightweight portable keyboards and heavier weighted actions. The touch sensitivity allows for dynamic playing, where volume changes based on how hard you strike the keys.
Controls are managed via physical buttons on the panel. You have access to functions like metronome, record, sustain, and drum kits. There are also transpose and vibrato options. The listing highlights 128 tones and 128 rhythms for varied soundscapes. Connectivity is handled through a micro USB port. This allows you to link the piano to computers or smartphones for MIDI data. A carry bag is included to protect the device during transport.
Setup and Daily Use Guide
Setting up this folding keyboard involves unfolding the unit and connecting power. The listing specifies a rechargeable power source, so you will need to charge the internal battery before first use. There is no mention of an included power adapter, so you may need to use a compatible charger. Once powered, the keys respond to touch sensitivity, meaning your playing volume changes based on how hard you strike them. This semi-weighted action provides some resistance, helping you build finger strength during practice sessions.
For daily use, the instrument offers a range of built-in functions. You can access a metronome to keep time, record your performances, or engage the sustain function. The control panel includes buttons for adjusting tempo, transposing keys, and selecting vibrato effects. You also have access to 128 preset tones and 128 rhythm patterns. Thirty demo songs are included to help you explore the sound library. The keyboard also features chord accompaniment options.
Connectivity is handled via a micro USB port. This allows you to link the piano to a computer or smartphone for MIDI data transfer. You can use this connection to compose music or record performances using external software. The device supports MIDI communication, making it compatible with most digital audio workstations. A carry bag is included, which simplifies transport. You can easily pack the folded unit for travel to school, outdoor sessions, or trips. The compact folded dimensions ensure it fits in small spaces when not in use.
Before You Buy This Folding Piano
Owning this folding keyboard requires you to consider how it fits into your daily routine. The semi-weighted keys offer a touch-sensitive experience, but they do not replicate the heavy resistance of a grand piano. If you plan to produce music, you must ensure your computer or smartphone has a compatible micro USB port. The listing mentions MIDI connectivity, so verify your device supports standard MIDI protocols before connecting. You will need to keep the carry bag handy for transport, as the unit weighs 11 pounds. Regularly check the charging port for debris to maintain reliable power. This model suits beginners who need portability. It sits alongside traditional portable pianos by offering unique storage benefits. However, if you prioritize authentic key feel over compact design, other options may serve you better. Keep the surface clean to preserve the wood finish and ensure long-term usability.
Check before you buy
- Verify your device has a compatible micro USB port.
- Check if your computer supports standard MIDI protocols.
- Ensure you have space to unfold the unit.
- Confirm the rechargeable battery meets your travel needs.
- Decide if semi-weighted keys suit your practice style.
