11. Conclusion

All other differences in equipment aside, the most important thing to consider when buying a stage piano is how it feels when you play and the sound it produces. Both of these are decided based on your preference and are often intertwined. Before purchasing a stage piano or any digital piano it is advisable to try as many models as possible. It has certainly happened before that one model is considered better than another that is better equipped simply based on subjective reasons.

It is better to spend too much time thinking about the pros and cons of a particular model than spending too little before purchasing. There isn’t anything quite as annoying as realizing, shortly after the expiration of your money back guarantee, that it would have been nice to have a keyboard with different features. Since stage pianos differ wildly in this respect it may be useful to create a personal checklist of your desired features and compare it to the models you’re looking at.

What is meant by polyphony or polyphonics?

The term polyphony refers to how many tones can be heard simultaneously. The technical capabilities of an electronic instrument is, as with a computer, limited by the capacity of its built in chip(s). The more tones an instrument should control, the more data the processor needs to be able to…well…process.

If you check the technical specifications of a digital piano you will see polyphonic specifications of 32, 64, 128 or even 258 notes. Your first reaction may be to think that you would never play more than 10 or so notes at once (unless you’re Jerry Lewis who also played with his feet). But you need to be conscious of the fact that you’re in the digital world now and that every note received, from a pedal for example, must be counted in terms of the polyphony. For digital pianos with stereo samples you’ll need to pay attention to the fact that the polyphonic value given is halved, as there are two ‘’voices’’ for each sound or sample. The higher the polyphonic value, the more closely the sound will resemble a real piano because multiple resonations and overtones can be played concurrently.

What is MIDI?

MIDI (Musical Instrument Digital Interface) is a data transfer protocol that allows digital information about pitch, tone length, and sound type to be communicated, recorded, or played back between individual instruments or between instruments and computers. More information about this subject can be found in our online guide for keyboards.

Many digital pianos have a MIDI-interface, generally an input and output, designated as MIDI-IN and MIDI-OUT. This allows you to access another keyboard or connect to a computer with a sequencing program. Notation programs also usually support MIDI protocols. Another option is to download songs with MIDI ports, especially onto devices which don’t have an USB port.

What should I look for in the controls?

When selecting a digital piano you should make sure that the knobs, sliders, panels and other controls are easy to reach while playing. Is it, for example, possible to switch easily between sound settings? Is it possible to select built-in effects and other functions with the press of a single button? Is there a touchscreen? Or are all parameters only selectable through a tiny LCD screen with cumbersome controls? An e-piano is essentially a computer developed by hardware and software specialists, and sometimes they just forget that a musician isn’t interested in reprogramming the entire system. So make sure the instrument will do what you want it to, and that you can ask it to do that on the fly!

What is arranger?

Arranger is a function which allows the player to be accompanied by (play along with) different styles from several instruments. This function can be found on most keyboards as well as digital pianos. At the push of a button an entire band or orchestra can be imitated according to the rhythms and styles of the player. For example, the player can make a cymbal rhythm in C major with an orchestra sound.
