|Realtime Automatic Note Detection for your MP3 music files.
|Having trouble figuring out all the notes in that tricky guitar solo?
Just load a MP3 music file, find an instrumental solo, and press the red Record Button. And all the while the MP3 file
plays, the notes of an instrument solo are automatically transcribed to a Notelist while they are animated to
Navigator's Driving View.
Navigator works by detecting the most dominant pitch at any given moment in time -- Navigator can not detect
multiple simultaneous notes.
Though Navigator can make reasonably accurate transcriptions in most circumstances, Navigator's note detector is
not absolute and occasionally makes errors and might add some erroneous notes. But Navigator's editing tools allow
you to quickly hear, evaluate, and delete or modify any false notes.
Navigator is designed to work on musical instrument solos, and is not really intended to detect the pitch of a human
voice. Harmonically dense instruments like electric guitars, saxophones, blues harmonicas, and clarinets will detect
better than harmonically sparse instruments, such as a flute or piano.
|Slowed-down Play Speeds Increase Detail.
Navigator can also detect notes at different Slowed-down Speeds, which play the music more slowly make
more measurements within the music, note detections at Slowed-down Speeds are much more accurate
than detections done at the normal play speed.
Slowed-down Speeds can also help the user gradually learn how to finger the notes of a solo as they play
along upon their instrument at a slower pace. To also help the user follow the playing notes, Navigator
can create a number of different animation schemes which vividly show the flow of upcoming notes.
Navigator also comes with other educational tools, such as the ability to mark and store musical phrases
of the MP3 recording. These stored musical phrases can later be reloaded from hard drive and played in
a Infinite Loop mode during practice sessions.
|Animation Choices for Visual Feedback.
To help users follow the music, Navigator comes with a couple of different animation devices: the DrivingView and the Revolver. The Revolver
resembles the face of a clock, but instead of having numbers for the hours, it has the notes' letter-names for the 12 pitches in an octave. As
the music plays, the currently detected midi note lights up at that note's position on the circle.
The DrivingView animation is much more sophisticated and shows future notes flowing into the DrivingView from its far right side. And at the
same time, the current playing note lights up on the DrivingView's rectangular gauge at the left. DrivingViews also come in different formats.
You can choose DrivingViews that have their notes flow vertically (far right), and also pick from different sizes of DrivingViews. And when the
music is stopped, you can select and edit the notes of a Notelist upon the DrivingView.
|More Midi Device Choices.
Nothing is needed other than Microsoft Windows, in order to use Navigator. Windows comes with a free, built-in, Midi Synthesizer which can
play the notes that the Realtime Note Detector finds.
Users can quickly pick from 96 stock Midi Instruments which are included with Windows while playing the music with the help of the Midi
Instrument Control. In the case below, the current musical instrument is "Percussive organ" which sounds similar to the Hammond organ's
Navigator can also access External Midi Devices that you might have connected to your computer. Then, while detecting notes or playing
Notelist transcriptions, the midi notes will not come from your computer's speaker but from the sound system you have connected to your
External Midi Device.
PitchScope Navigator is a type of educational software and is simple enough to use for children 8 years and older, if an adult or older child will
read the Online Help File, and show the child Navigator's basic commands. This software does not require a child to know how to read music, or
even how to play a musical instrument.
At its simplest, all a child must do to us the software is to load a MP3 file, and press the Play Button. As the music plays, the newly detected
notes animate across the DrivingView as they are being played through Windows built-in Midi Synthesizer.
PitchScope Navigator can be used as a discovery tool that introduces a child to some of the building blocks of music -- almost like a microscope
with which to observe the notes of an instrumental solo.
