MIDI Record Strip
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
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
Designed for easy installation.
MIDI record strip is extremely sleek and low profile, and easy to install.
Traditional recording retrofit strips can require precise height positioning
and occasional keyboard modifications. These steps are unnecessary with
PNOscan's optical technology. The PNOscanTM MIDI record strip can
also be retrofitted on a piano you already own.
