At a weekend conference, the digital piano was in fact\nelectronic piano. I don\u2019t know whether people make that difference (digital or\nelectronic) or whether the naming system is consistent across manufacturers.\nBriefly, digital piano has better sounds (and more effects) than electronic. It\nsounds like a major difference, but some of it is due to very small margin in\ndesign.<\/p>\n\n\n\n

On small margins, human can only survive in small margins of temperature.<\/p>\n\n\n\n

I read that scientists discovered a planet a few years ago\nwhich they named GJ1214b. They worked out this planet is made much more of\nwater than earth. While the presence of water suggests life might exist there,\nit has a temperature of about 450F. Ouch, human can\u2019t survive there.<\/p>\n\n\n\n

We can survive on earth because, by chance or deliberate act, it has a temperature range that exact suits human. When temperature goes much colder or hotter than normal, we find it really uncomfortable and need to make adjustment such as install air conditioning or heating system. <\/p>\n<\/div><\/div>\n\n\n\n

Most musicians bring their own instruments when they perform. This is the same with musicians leading worship. Pianists, organists and drummers are exceptions (any others?) \u2013 we play on the instruments provided.<\/p>\n\n\n\n

The electronic piano at the conference venue was probably one of the earlier models; not only that the sound samples were really basic to the point it seemed the manufacturer didn\u2019t care, the sounds were also very \u201cthin\u201d \u2013 it does not have the fullness of sound that varies with touch. I struggled in explaining this to people. <\/p>\n<\/div><\/div>\n\n\n\n

The piano \u2018touch\u2019 is a difficult concept to explain in the first place, since on the acoustic piano, the keys that you play then go through a long series partially connected mechanism. A good digital piano is able to respond to the touch from the piano to produce the fullness of sound expected. Some digital piano will do much more, but that\u2019s the basic.<\/p>\n\n\n\n

A good digital piano reacts to the smallest subtlety of a pianist\u2019s touch on the keys. A very small margin (e.g. velocity, pressure) creates different effect on the sound. We take this for granted. The lack of expression on this electronic piano at the venue frustrated me: given the effort in making such an instrument, its sounds were so poor. <\/p>\n\n\n\n

From a distant, the electronic organ looks promising. In a similar way, GJ1214b\u2019s water suggests life. But we can only survive in a small margin of temperature that only Earth provides for. The electronic piano was built with a margin too small for expression.
