Auto accompaniment
Auto accompaniment feature on the digital piano.
Auto Accompaniment is a melody of a specific style played by the instrument under user control. Such control is carried out by the left hand: the musician takes certain chords on the left side of the keyboard, and the electronics of the instrument adjusts the auto accompaniment melody to the key of the taken chord. Thus, this function allows you to accompany the main part with a full-fledged accompaniment, while the musician only needs to set the chords.
Among digital pianos, unlike synthesizers, this function is rare. This is due to the general specialization of this class of instruments (not least professional music-making, including as part of an ensemble or orchestra). However, auto accompaniment is available on both relatively simple and high-end digital pianos.
Accompaniment styles
The number of Auto Accompaniment Styles (see above) originally stored in Digital Piano memory.
Different auto accompaniment styles differ from each other in the same way that different melodies differ from each other — in tempo, time signature, rhythmic pattern, set of instruments used, etc. Accordingly, the more styles initially available in the instrument, the wider the choice of the musician and the higher the probability of finding the option that best suits a particular situation. However even numerous styles does not guarantee that among them there will be a suitable one; in addition, we note that with the same number of styles, their specific set in different instruments can also be different. However, custom styles can be provided for this case (see below).
Summarizing, we can say this: if you plan to work intensively with auto accompaniment, in addition to the number of styles, it will not hurt to clarify their specific range.
Learning mode
The presence of a training mode in the digital piano.
As the name suggests, this mode is designed to teach the game. At the same time, usually, it provides different levels of difficulty — from the most basic, for those who are just starting to master the "keys", to the advanced one, which allows you to train your technique and improve your existing performance skills. However, anyway, the principle of learning is the same: the tool independently tells the student which keys to press at one time or another. Such hints can be in the form of a backlight (see above) or as a graphic on the display. Such a method is doubtful from the point of view of classical academic learning, however, it is undoubtedly more convenient and faster than reading musical notation. Moreover, the instrument can also play the role of an examiner — launch prompts at the original tempo of the melody and check how accurately the student hits the notes.
Also note that
the learning mode requires the obligatory presence of a metronome (see below).
More features
Additional features and sound customization options provided by the instrument in addition to those listed above. In this paragraph, usually, various original proprietary technologies and solutions are indicated; the specific meaning of these functions is best specified in the documentation for the tool.
Inputs
— Mini-jack (linear). Any
line input is designed to receive an audio signal in analogue format. Such an audio signal can be played back by the instrument itself through the built-in speakers, external speakers or headphones, switched to external equipment (for example, an amplifier or audio receiver), or recorded (if you have a sequencer, see above). In digital pianos, the most popular is the first option — playback; typically, the line-in sound either serves as an accompaniment to the main part or provides additional effects. As for the mini-Jack standard, this is a miniature plug, also called "3.5 mm" and known to many as a standard audio jack on a smartphone, laptop or computer. However, this standard is also very popular in digital pianos — among external signal sources, mini-Jack plugs are generally more common than full-size Jacks.
— Jack (linear). Line input using a Jack type connector (aka "6.35 mm"). In terms of purpose, such an input does not differ from the mini-Jack type input described above. As for the connector, it is almost 2 times larger than the mini-Jack in diameter — however, given the dimensions of digital pianos, this cannot be called a serious drawback. At the same time, the Jack socket provides a better and more reliable connection, with less likelihood of interference. At the same time, for a number of reasons, this type of connector is used somewhat less frequently in digital pianos.
— MIDI in.
...An input that allows the Digital Piano to receive MIDI signals from external equipment. MIDI is a standard signal format in electronic musical instruments; such a signal (MIDI-event) is created for each keystroke and contains information about the note number, strength, speed and duration of pressing; these signals can then be recorded and/or played back in a specific tone. The ability to receive MIDI events from external devices can be useful, for example, when playing two keyboard instruments at once (to play all the music on one of them, with better sound quality), or to use the digital piano as an adapter for another instrument that does not having the desired tones. In addition, technically, a MIDI signal can be switched to other devices (see "Outputs — MIDI thru").
— USB to device (type A). USB connector that allows you to connect various external devices to the digital piano. However, most often the range of such devices is limited to "flash drives" and other drives. However, even this functionality can provide very extensive additional features: you can play backing melodies from a flash drive, update user timbres and auto-accompaniment styles (see above) or even instrument firmware, and copy materials recorded by a sequencer to a flash drive (or even write music directly). ), etc. Specific features in different models may be different, this point should be clarified separately.
— Card reader. A device for reading memory cards — usually, the popular SD format. By purpose, this function is similar to working with a USB flash drive (see above), adjusted for the fact that memory cards will be convenient primarily when exchanging data with a laptop — almost all modern laptops are equipped with card readers, which cannot be said about desktop PCs.Outputs
—
USB to host (type B). Connector for connecting a digital piano to a computer using the USB standard; in this case, the instrument plays the role of a peripheral device. The possibilities of such a connection can be different: recording live music, updating firmware, voices and auto accompaniment styles, using the digital piano as an external MIDI keyboard, fine-tuning the instrument and troubleshooting, etc.; specific functionality varies from model to model.
—
MIDI out. An output that allows you to broadcast MIDI signals (MIDI events) from the Digital Piano to external devices. A MIDI signal is, in fact, a "preparation" of sound: a signal generated when a key is pressed and containing information about the note number, duration, and force of pressing. Based on this signal, the electronics of the instrument (or other device) generates the sound of a certain timbre. The MIDI output can be useful for connecting a digital piano to, for example, an external sequencer for recording, or to a synthesizer for playback in a tone that is not in the piano itself.
—
MIDI thru. Output used for switching MIDI signals. The description of such signals is given above, but here we note that the MIDI thru output duplicates the signals received at the MIDI input of the digital piano. This function can be useful in some specific cases — for example, connecting sever
...al electronic instruments together.Display
The type of display installed in the Digital Piano.
— Monochrome. Single colour
display, not capable of working with a colour image; such screens are often referred to as "black and white", although other colour combinations are actually possible (for example, a blue image on an orange background). Despite their simplicity, the capabilities of such displays are quite sufficient for both simple and fairly advanced digital pianos; and they are inexpensive. Therefore, most models that have a screen at all use monochrome matrices.
- Coloured. A screen capable of displaying a multicolor image. Such displays are more advanced than monochrome, they not only look nicer, but also provide more information and visibility (colour is often used as a way of highlighting). At the same time, such functionality is rarely required in the case of digital pianos, and colour screens are noticeably more expensive. Therefore, this option is typical mainly for premium-class instruments.
Power consumption
The power consumed by the tool during normal operation.
The cost of electricity, as well as connection requirements, depend on this indicator. At the same time, we note that digital pianos require relatively little energy — even in the most powerful and advanced models, consumption usually does not exceed 60 watts. So in fact, power consumption data is required mainly for specific cases — for example, to calculate the total load when connecting a tool to an autonomous generator along with other devices. In addition, this information may be useful when assessing the power of the built-in speaker, for more information, see "Built-in acoustics".
In box
Additional items included with the instrument.
— Music stand. A music stand mounted above the keyboard, in front of the musician's eyes. Note that in this case, only the detachable music rest supplied with the portable instrument is meant (see "Body"); in stationary digital pianos, by definition, such a stand is available; moreover, it is often a non-removable part of the body.
— Pedal. Only portable digital pianos (see Body) can be equipped with an external pedal. stationary are equipped with built-in pedals. Note that there is usually only one such item in the kit, even if there is more than one input for the pedals. However, this cannot be called a serious drawback: situations where a musician needs more than one pedal are extremely rare. For more information about the inputs and the pedals themselves, see Connectable Pedals.
— Power Supply. Power supply for connecting the tool to the network. Even for portable tools, an outlet is often the most convenient way to power; and in stationary cases, other options may not be provided at all. Therefore, the power supply is an almost indispensable element of the digital piano package. The absence of such a block in the kit, usually, indicates that it is made built-in; however, this is rare.
— Disk. An optical disc (CD or DVD) containing various digital piano supplements. These can be instructions and other documentation, drivers for connecting to a computer, specialized software for edit...ing music on a PC, etc. Such a medium can be very useful if you need access to information or specialized software, but there is no Internet connection at the moment or there is a problem with it.
— Rack. Stand for floor installation of the tool. It is used only in portable models (see "Chassis") — stationary, by definition, do not require additional stands. Such a device, usually, is made folding, which provides ease of storage and transportation. Racks are also sold separately, but in some cases it is more convenient to buy a stand immediately, along with the tool.
