Music chord recognition

Karaboss is now able to display the chords contained in a MIDI file.
Chords can be displayed dynamically, i.e. at the same time as the lyrics (for singing along with an instrument, for example), or at a standstill for more detailed study of a song and its accompaniment.

The chords of a song can be obtained in two different ways:

They can be written manually in the song lyrics.
For example: the text “[Am] Little house [G] on the prairie” indicates that you should play the chord “A minor” and then “G”.
Karaboss will extract the chords from the text and display them above the lyrics.
Adding the chords to the lyrics represents a considerable amount of work, but in return, the chords displayed will be exactly those you have chosen.
Or they can be automatically discovered by Karaboss, which is still a little experimental 🙂 and therefore less accurate than the first method. But in return, it’s much less tiring.
Note that chords placed voluntarily in the lyrics take precedence over those discovered by Karaboss.

The chords are written in international format (C, D, E, F, G, A, B)

I. Displaying chords in the karaoke window

Simply press the “Chords” checkbox in the right-hand panel of the karaoke window, and the chords are immediately displayed above the song text (whether already present in the lyrics or discovered by Karaboss).

Chords + lyrics

Press the checkbox again to return to normal mode: karaoke without chords.
In the case of a file containing the chords written in the lyrics, this is rather indigestible, as can be seen below:

Lyrics with embedded chords

II. The “Chords” module

Click on the “Chords” button in the explorer to access the “Chords” module.

This module has three tabs

  • A first tab displays the song’s chords in the form of a grid
  • A second tab displaying the chord map
  • third tab that displays the song text with its chords.

1. The chord and lyric line

The first tab displays on a line each beat of a bar, with the chord to be played and the syllables belonging to that beat. When the song is started, this enables the musician to play the right chord at the right moment, and possibly sing along with the song.

To make synchronization easier, the song scrolls on the screen, with the square corresponding to the beat and bar played highlighted.

The button bar can be used to enlarge or reduce the size of the squares.

2. The chords map

The second tab displays the chords map contained in the MIDI file.
When the song is started, the box corresponding to the beat is highlighted.

The button bar lets you

  • enlarge or reduce the size of the cells.
  • exports the chords map in PDF format

3. The score

The third tab displays the score of the song, qith lyrics and chords above the text.

[Fixed]The last update of Windows 10 (2004) available since May 2020 removes the VirtualMidiSynth synthesizer!

At the very beginning of June of this beautiful year 2020, and following the last update of Windows 10 in version 2004, I had the unpleasant surprise to see my MIDI player using again the horrible “Microsoft GS Wavetable Synth” instead of VirtualMidiSynth.

This image has an empty alt attribute; its file name is image-1.png

It is quickly noticeable by ear, the MIDI sound without sound bank is quite unbearable….

A reinstallation of VirtualMidiSynth is not enough, you have to reinstall VirtualMidiSynth each time you reboot your machine.

Or more simply: go to the “Start” menu > “VirtualMidiSynth” > “VirtualMidiSynth Configurator”.
This one then detects that it is not correctly installed and then puts the MIDI driver back in place, but only for the duration of the session.

The developer has well identified and taken into account the problem on his site, but it will not be corrected for some time.
This is a change made by Microsoft in the Windows driver management.
Source: https://coolsoft.altervista.org/en/forum/post/4775#post4775

Let’s hope that the solution will not take too long for VirtualMidiSynth users.

Updated on September 27, 2020 :

The developer of VirtualMIDISynth has fixed the problem with version 2.10.
Originally, it was not a bug, neither from VirtualMidiSynth nor from Microsoft, but from the way new versions of Windows handle drivers.

The virtual guitar

Play guitar with Karaboss

Karaboss has a new module made for bassists and guitarists.
Learn your favorite guitar tracks with Karaboss: Play a song and the playing notes will appear on a virtual guitar neck where you have to put your fingers!

How?

A video is available here.

Select a song in the explorer and click on the “Guitar” button  on the left navigation bar to display the virtual guitar.

Select Virtual Guitar

How to use the virtual guitar?

Each of the guitars included in the MIDI file is displayed and plays its own score.
You will find generally a bass guitar and one or several guitars.

Bass guitars are colored differently from other guitars.

Virtual Guitar

  • To remove one or more guitars from the display, click on the “X” button.
  • You can also slow down or speed up the performance of the song by clicking the “+” and “-” buttons.

What is it for?

Obviously, the display algorithm of positions often gives a very approximate result and far enough from what a normal guitarist would use.
(a normal guitarist does not have fingers twenty centimeters long).

A priori, the perfect algorithm should not be simple…
See this thesis from Elias Mistler proposing to use neural networks :  Generating Guitar Tablatures with Neural Networks

or this one, from  Daniel R. Tuohy:
Creating Tablature and Arranging Music or Guitar with Genetic Algorithms and Artificial Neural Networks

That said, this module, very visual, allows to apprehend a piece faster.

How to sort your MIDI files?

Manage a collection of MIDI files, why and how?

Own thousands of MIDI files, why not? But from a certain number, manual sorting is not enough anymore.
How to make sure of their uniqueness? How to be sure that we do not already have those we add?
Karaboss offers powerful and effective dual detection functions to support you in this daunting task.

Owning a large number of files, basically, is no use if we do not do anything with them.
Except maybe if you have a collector’s soul. But why on earth collect MIDI files when you can collect cheese boxes?

Well, you must have the time to listen to them, or worse, learn to play them if you are a musician, or to sing them if you are a singer.

But be aware that, anyway, even if you have astronomical quantities, you will never have the one you are asked, or you dream to add to your repertoire.

And then often, when you have the right file, it is double, triple, quadruple etc …
Among these duplicates, some have excellent sound quality, but sometimes downright disastrous.

That’s it, for this preamble. The idea is not to know what to do with these 30,000 files, bequeathed by your grandfather, but to make them unique.

Besides having duplicates of the same title can have several meanings.

Different orchestrations of the same piece

In this case, having several versions of the same song is of obvious interest.
Acoustic version, electric version, live version etc …
If the quality is at the rendezvous and if you are a musician, or fan of the artist, it may be interesting to keep them.

The same orchestration, but of very different qualities

In this case it will be necessary to keep the best version.
The only way to do this is to listen to each piece and ruthlessly eliminate those that you think are bad.
It’s hard to throw, I know, it’s too definitive.
Who does not have the versions (1), (2), (3) or even (4) of the same piece?
This is unfortunately sometimes due to the fact that no version really stands out, and in this case why throw this or that version?

And finally the real doubles

They are carpet insidiously in the depths of your directory trees. But how to identify them with certainty?

This is where the utilities offered by Karaboss become interesting!

To do this, Karaboss offers two Search modules:

  • Look for duplicates within your library or any other tree.
  • Look for duplicates in relation to your library.
    In this case, compares the files you want to add to your library to eliminate the ones you already have.

Keep reassured, Karaboss does not search for duplicates based on unsafe criteria such as file name or file size.
To detect duplicates, the software will create an index of all your files, each time calculating the MD5 checksum of the file. If two checksums MD5 are identical, it means that both files have identical content, without necessarily having the same name or the same size.

In addition, when duplicates are detected, no deletion is made.
At the end of the search process, you have the choice to either move the duplicate files to a subdirectory named “doubles”, or touch nothing, but simply display a list of duplicates allowing you to manually process each file.

In the case of moving duplicates to a subdirectory, it is the file with the shortest name that is moved (we don’t want to destroy all your renaming work!)

Choosing to move duplicates to a subdirectory is especially useful when you want to import new files into your library. This automatically deletes the files you already have from your import directory.

How to proceed ?

You access the file management utilities from the Karaboss Explorer.

Menu “Tools” > “Manage my files“

How to Hear Your Microphone Through Computer Speakers

How to Listen to the microphone?

When you launch an application on your PC, a video, a mp3, or Karaboss Karaoke player, the sound is transmitted to the speakers.

Unfortunately, the sound of the microphone, remains inaudible …
And a Karaoke without any microphone…

Indeed, by default, Windows does not automatically output the audio through the computer’s speakers.

This is on purpose.

Why ?

It is not to complicate your life, but simply to prevent the microphone, capturing the crystalline sound of your voice, but also that of the speakers, does not create an infernal loop of amplification, which ends with a shrill sound, the effect Larsen.

The sound emitted by the speakers is picked up by the microphone which transmits it amplified to the speakers. This signal is again picked up by the microphone and re-amplified, and so on.

So avoid this on a laptop where the speakers and the built-in microphone are very close, but it is quite possible when using an external microphone and not directed to the speakers.

The solution ?

  • Right-click the speaker icon in the notification area.
  • Choose the “Recording Devices” menu, and the window below is displayed.
  • Select the “Registration” tab.
  • Select the active microphone (make it active if necessary) and click on the “Properties” button.

Select micro
The following window is displayed:

Activate micro
Check the box “Listen to this device”

And now you listen the sound of the microphone in your speakers.
Unfortunately, this manipulation, excessively simple, does not always provide the expected result.

Latency

You listen your microphone in the speakers, but the sound is offset by a fraction of a second. And in the case of Karaoke, it’s just unusable.

On recent versions of Windows, the activity “resident” (everything that runs in the background) is important (services, applications, anti-virus etc …) and sound management is not managed on a high priority.

I was able to successfully test one of the methods recommended by gurus sites: the installation of ASIO drivers.
I did not go so far as to install specific drivers for my motherboard, but the generic ASIO4ALL drivers available here.

After installation, the result was rather correct, but maybe it’s due to my configuration, and it will not work everywhere.

The virtual piano

A virtual piano in Karaboss

Karaboss can now teach you how to play the piano!
Even if you can not read the scores, learn to play the piano with falling notes.

How to do ?

First, select a piano piece in the explorer of Karaboss.
Two: click on the new “Piano” icon button on the left toolbar and that’s it.
When the song contains several  tracks, they are displayed in different colors.
Typically:  left / right hand for the piano.
You can remove unwanted tracks with the score editor

Keyboard shortcuts make your life easier:
You just have to type “space bar” to launch the player, “space bar” again to pause and when paused, “left key” to stop.

And if it’s going too fast or too slow, hit “+” or “-” keys to speed up or slow down the tempo.

Piano Training

See these videos on Youtube :

Ray Charles – Georgia On My Mind

The Handsome Family – Far From Any Road (Soundtrack True Detective)

Tips:

You can build your own files with the music score editor by removing tracks and keeping only the piano track and then split the remaining track into two tracks to have left and right hands.

You can even print your music scores in traditional notation using the score editor of Karaboss (export to PDF format an than print).

What to download?

Do I have to download Karaboss and its two complements?

download

Karaboss is a complete application that works perfectly from its installation.
However the addition of two complements will make Karaboss much more attractive to your ears and those of your audience.

To begin: install Karaboss and nothing else

In theory, only Karaboss is essential: once installed, you will have access to all of Karaboss’s features: the karaoke player, the score editor, the virtual piano, etc.
So you can start by downloading and installing Karaboss to familiarize yourself with its various features (cool!).

Download two complements to improve the quality of the sound

Well, you finally master Karaboss on the fingertips, but quickly you find that the quality of the sound is not at the rendezvous. It is not neither Karaboss nor your PC that are involved, but the use of MIDI files that requires some adjustments.
Click here to find out why and how to fix it.

Once Karaboss mastered, and your ears permanently martyred, do not hesitate to return to this page and download

  • the synthesizer, which will replace the basic one provided by Windows,
  • and the proposed sound bank, which will replace the sounds synthesized by the sounds of real instruments.

Those two addons will greatly improve the rendering of your songs!

The downloads

  1. Karaboss
  2. A new synthetizer
  3. A Sound Bank

Which resources and useful links?

What are the best Karaoke download or karaoke files and other great places for singers or budding composers who want to learn about MIDI sequencing.

How to get MIDI or karaoke files?

Good question…Music Studio
A long time ago there was a lot of it on the net.
This time is over: We must now look long before finding his happiness and we often draw a blank.

The problem is that uploading a MIDI file for free comes up against legal considerations, with respect to the rights holders of the original work, and directly competes with the activity of many professionals …
– This is a copy of an original artwork even if the quality of the sound is certainly not at the level of the original one (To say nothing of the absence of the singer)
– This is the equivalent of a score in direct competition with that of the score editors.
– Sometimes these files are created and put on sale by professional musicians, so it is forbidden to put them online.
– Same for MIDI files that you have created yourself, except your own compositions.

In France, for example, the Code of Intellectual Property states that “any representation or reproduction in whole or in part without the consent of the author or the rightful assignees is unlawful, even for translations, adaptations, transformations or even arrangements that may arise from the artwork. ”

It is not the purpose of this page to make a judgment on the orientation of the internet, but it is clear that the “blessed” era of free internet is over and the merchandization of the MIDI file is a fact.

The purpose of this page is to list the different possibilities and give some links that point to files still free of charge.

Google search:

It is usually enough to launch Google by doing a search on “Midi Files” or “Karaoke Files” to get good results.

We then come across sites that offer self-service files, others that require the creation of an account, and finally there are sites that offer, for a small fee, files created by professionals and therefore good quality (you can even order a file if it has never been put in MIDI format)

List of links to sites that offer Karaoke files for free download:

Registration required

The lifetime of sites that offer free MIDI files for download is often short … There is no guarantee that these links will exist in a few months. Thank you for pointing out those who died.

Some interesting sites to consult for singing, to equip yourself:

The Sound Banks (Soundfonts)

Technical stuff: structure of a typical karaoke (.kar) file

We find everything in nature: files whose lyrics have syllables in “text” format, others in “lyric” format, sometimes they are not syllables, but whole lines, or conversely letters entered one by one!
No standard obviously, and thus charges to the MIDI reader to adapt itself progressively to the discoveries of exotic files ….
But here is what we would like to expect 🙂

That’s it, and if you have, you too, some good addresses, feel free to share them.
