New QRS PNOscan

The PNOScanTM MIDI Record Strip is extremely sleek, low profile, and easy to install.

The best record technologies sense the movement of the keys continuously. This means they see the entire movement of the key up and down. That data can then be used to set trigger points and assign controller values. Leaving the most accurate recording possible. The sensors also need to be non-evasive, in other words nothing effects the touch of the key, there is no mechanical link to cause potential noise or breakage. Adding weight to the key is a way to add sensors but they modify the touch of the action and action repairs become a problem. There are several types of recording technologies currently used are hall effect, flag, tft, optic – flag being the most popular and cheapest is used by the Japanese and some Korean knock offs of an early Gulbransen strip. TFT has a mechanical element to it and has been shown to be inaccurate. The only real solution is an optical sensor – but even these have issues unless you are able to filter out the noise from lights, smoke, radios and adjoining sensors. QRS’s patents speak to this capability – without it the setup of an optic sensor is much too delicate a procedure and prone to hot notes, false triggers and erroneous events. PNOscan is by far the best product ever produced for recording a performance on an acoustic piano. Recently long distance learning has been pushed. Off the shelf products accessories make it happen. These products are available to QRS. QRS’s systems are compatible if this is the direction you want to go.

PNOscanTM MIDI record strip is designed to be a valuable high-performance solution for discerning musicians and composers yet is reasonably priced enough and practical for everyday use by piano students, music teachers or anyone who wants to save their piano performances or recitals. Recordings can be output as standard MIDI files or on the QRS PNOmation® player piano system for more dynamic playback.
