The very best record technologies sense the movement of the keys continuously. This suggests they see the entire motion of the key up and down. That information can then be utilized to set trigger points and designate controller values. Leaving the most precise recording possible. The sensing units also need to be non-evasive, in other words nothing results the touch of the key, there is no mechanical link to trigger potential sound or damage. Including weight to the secret is a method to add sensors however they modify the touch of the action and action repairs end up being an issue. There are a number of types of tape-recording innovations presently used are hall result, flag, tft, optic - flag being the most popular and least expensive is used by the Japanese and some Korean knock offs of an early Gulbransen strip. TFT has a mechanical aspect to it and has actually been shown to be inaccurate. The only genuine solution is an optical sensor - however even these have issues unless you are able to filter out the noise from lights, smoke, radios and adjoining sensors. QRS's patents talk to this ability - without it the setup of an optic sensor is much too delicate a procedure and vulnerable to hot notes, false triggers and erroneous occasions. PNOscan is by far the best product ever produced for recording a performance on an acoustic piano. Just recently long distance learning has been pressed. Off the rack items accessories make it happen. These items are offered to QRS. QRS's systems work if this is the instructions you wish to go.
