Digital Sound Effects in Synthesizers
Description of the main speakers or as they are called digital effects used in synthesizers and digital pianos. Terms that are often heard, but perhaps not always understood.
Acoustic Effects (digital effects) - special effects, changing the sound timbres. The most common acoustic effects are reverb and chorus, also some models of synthesizers have built-in DSP, which gives an opportunity to use a much wider number of acoustic effects.
Reverberation (Reverb) - acoustic effect, which means the sound that remains after the cessation of the sound source as a result of multiple reflections of sound waves from the walls. This effect is specially used in architectural acoustics in the design of concert halls. Using the reverb effect to add to the sound of a synthesizer or digital piano sensation of playing a large concert hall. Virtually all digital pianos and synthesizers contain multiple (from 4 to 16) of reverb. When choosing the style or song automatically selects the type of reverberation that is most appropriate for your tone.
Chorus (Chorus) - acoustic effect, when the sound performs several identical timbres. In English Chorus - a "chorus", ie the effect of "chorus" for the violin tone creates a feeling that the melody played by a violin - Violin Choir. Chorus creates a rich surround sound. Virtually all digital pianos and synthesizers contain multiple (from 4 to 16) of the chorus. When choosing the style or song automatically selects the type of chorus, most suitable for your tone.
Acoustic resonance (Acoustic Resonance) - acoustic effect of transferring the resonance string acoustic instrument. It adds extra realism of timbre, transmitting sound of string instruments - guitars, violins, etc.
DSP-effects - the effects obtained by using DSP (Digital Signal Processor) - processor digital signal processing. DSP - is a specialized high-speed processor is used for complex sound processing. In some models of synthesizers and digital pianos built around a hundred different DSP-effects.

Piano Cleaning
In connection with the often encountered questions about the need to keep the tool clean and on the basis of experience in rehabilitation and resuscitation "of the old piano, long decommissioned and stored in inappropriate conditions (garages, sheds, attics, basements and even the balconies, terraces and etc.), find it impossible to attempt to provide advice to owners of tools and novice tuner.
Requiring content tool to clean due to two components, namely: health and quality of sound.
After many years I have developed the practice of pre-cleaning the piano in front of his setup. I can recommend it to all beginner tuners, as experienced professionals know it perfectly. I do not recommend do this to the clients themselves, for them, I cite it only for the purpose of focusing on this, at first glance seems simple, but as it turns out, large enough and, most importantly, obligatory and necessary process for each configuration.
For example, I can provide detailed technology very, very "running" tool. Work tools are usually located in a fairly satisfactory condition, and below technology can be somewhat simplified. It is well known that if the piano ever played, the mole there feels "uncomfortable". However, there are cases when the instrument is recently in the active operation, and his state, in terms of dust and other contaminants, just awful. This is because prior to its acquisition, it is stored for a long time in poor conditions, and before commissioning, maintenance work carried out badly and formally, or were not implemented at all. An indirect indication of this may be unaligned keyboard under the keys which mole "ate" pads.
After the dismantling of parts of facing and opening the keyboard, made pre-cleaning of parts of mechanisms with a vacuum cleaner. One must be careful in the hammer mechanism, so as not to damage the parts.
After this you should carefully examine all parts, assemblies and connection mechanism of the piano and to remove, possibly resulting from careless storage, the remnants of life harmful "pets". Basically it is the consequences of active breeding in the textile, felt and felt part that moth. It will be useful in various sizes and configurations of the brush, first with a hard, and then with a soft pile. Then I try to persuade the client that, in connection with the unsatisfactory state of the tool is forced a little "popylit", removed the vacuum cleaner hose "ejection" and "blew" the remnants of dust. The process is usually accompanied by tragic exclamations client, watched in horror on how to take the "hundredth" the dust settles on furniture apartment. To this we must be prepared to convince the hostess that "art requires sacrifice."
A classic and effective way to combat moth is tea tree oil. It is packaged in containers of 3-5 grams, is set in the basement of the lower part of the tool, the lid should do the small hole. The replacement must be done once every six months. In our steppe under very spectacular plain white wormwood. A small whisk to "save" the piano from moths from six months to a year.
But not only the moth is a pest piano, although it is most common and widespread, the practice of observing repeated instances where under the keyboard, for some reason in the 4-5 octave, found a classical mouse nest, sometimes with a mummified baby mice. This occurs most often on the first floor apartment buildings or the operation of the tool after its prolonged storage in inappropriate conditions. As construction materials mouse, often used newspaper.
The analysis showed that the mouse, as the entrance to his "housing exhibition" dwelling use pedal box, but nothing else - "a matter of technique. The old tuner, in a state of the characters in the famous painting "Hunters in camp, there were cases of successful exploitation of the piano as a shelter, such representatives of wildlife as pets hamsters, chipmunks, and even proteins. Nothing on this occasion I can not say we whites do not live, they need wood, but we have more steppe and even desert.
I hope that convincingly showed that hygiene is a necessary tool for cleaning is also important, moreover, is required. I will cite only one case, which convincingly confirms this conclusion. We were in town, after the events, one family moved from Chechnya. After some time the girl became ill with severe allergies. After numerous medical interviewers was diagnosed and the most likely allergen - domestic mouse. The apartment is new, modern, European performance, third floor, no garbage, furniture, all new, Italian. Performing the piano tuning, by the way very, very good tool, under the keyboard, I found a mouse nest. Everything fell into place, the disease has arisen girl immediately after the acquisition of second-hand piano and knows how stored before. Each year now, I configure a piano, a serious disease girls, even on surprise to doctors and to the great satisfaction of parents, was held immediately after the adjustment.
The question of the influence of dust on the quality of sound production also is important, of course, pure instrument sounds "cleaner" and, to my ear, a little louder, and in some cases, this note and customers.
On this occasion, I can not dwell on the massive case detection in an instrument of foreign objects found me when you set up. The various coins, sometimes old and valuable, needles, pins and all kinds of pins, scissors, nail files for nails, combs, pots out of cosmetics, boxes of matches and some matches and still have lots and lots of all "junk", sometimes quite voluminous and incomprehensible in the way swallowed. Often it is found during the operation piano when he refuses to mechanics. No less often all that breaks up in the configuration process. Some of the most clever and resourceful children who engage in music "with a stick, often taking advantage of this" throw "at the piano, and refuse, at least for a short time before the arrival of the tuner from the lessons, making a unique vacation from the hated object.
Thus, on the basis of the foregoing, let me note that the "vacuum cleaned under the keyboard once in twenty years, it's ok", the statement is not quite correct, I think that such a procedure is desirable to do still more often, although, of course, depends on the conditions operation; in elite concert audiences, with climate control, periodic wet cleaning and maintaining the required parameters of humidity and temperature, the problem is less relevant.
