Chorus
The presence of the chorus effect in the digital piano.
Initially, this effect was developed as an attempt to simulate the choral sound of several instruments of the same type. Even a perfect choir never plays 100% in sync, which is what the creators of the chorus tried to reproduce. This effect works as follows: several copies are taken from the main signal, which are played along with it — but not strictly simultaneously, but with a small (up to 30 ms) delay, selected randomly for each individual signal. This really allows to imitate the effect of polyphony to a certain extent, however, such sound is still far from a full-fledged choir. However, the
chorus itself is quite interesting as an additional effect.
Brightness
The ability to change the
brightness of the sound of certain timbres or tracks.
Brightness determines the overall colour of the sound — from soft, smoothed to sonorous, sharp. This feature allows the player to adjust this coloration to their preference, and thus further expands the possibilities for customizing the sound of the instrument.
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 several electr
...onic instruments together.Built-in acoustics
The power of the native acoustics installed in the Digital Piano.
This indicator directly affects the maximum volume that the instrument is able to produce "on its own", without connecting external speakers. At the same time, it is worth noting that many manufacturers go to the trick and indicate in the characteristics not the rated power (rms power when operating at full volume), but the peak power, which is the highest power that the acoustics can deliver at short “ups” of volume. Peak power values can be quite impressive — in the tens and hundreds of watts — but these figures have a very indirect relation to the actual capabilities of the speakers. Therefore, before choosing, it is worth clarifying what kind of power is mentioned in the characteristics. To do this, it is not necessary to look for detailed data on the instrument, it is enough to compare the power of the speakers with the power consumption (see below): if the claimed power of the acoustics is greater than the power consumption of the entire instrument, then the manufacturer indicated exactly the peak value.
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".
