The very best record technologies pick up the motion of the keys constantly. This suggests they see the whole motion of the key up and down. That data can then be used to set trigger points and designate controller values. Leaving the most precise recording possible. The sensing units also require to be non-evasive, in other words nothing results the touch of the secret, there is no mechanical link to trigger potential noise or breakage. Adding weight to the secret is a way to include sensing units but they customize the touch of the action and action repair work end up being a problem. There are a number of types of tape-recording technologies presently utilized are hall impact, flag, tft, optic - flag being the most popular and most affordable is utilized by the Japanese and some Korean knock offs of an early Gulbransen strip. TFT has a mechanical element to it and has actually been shown to be incorrect. 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 adjacent sensing units. QRS's patents speak to this ability - without it the setup of an optic sensor is much too delicate a procedure and vulnerable to hot notes, incorrect triggers and incorrect events. PNOscan is without a doubt the best product ever produced for recording an efficiency on an acoustic piano. Just recently long distance knowing has actually been pushed. Off the shelf products accessories make it take place. These items are offered to QRS. QRS's systems are compatible if this is the instructions you want to go.
