Daylight saving time and libraries

Among the tools present in the MusiCHI library manager, the one used most frequently is the synchronization between the file system and the libraries (or should be).


For example, if you delete a CD, or rename the folder where it resides, or even simply edit the audio files’ metadata in the tagger, you want to use this tool. In the last case, the time stamp of the file will be modified (Windows will store the date/time of editing).  When a user refreshes a CD in a library, the date and time of this action is recorded as well inside the lib. By comparing these two time-stamps, well, if the file’s modified date and time is more recent than the one existing in the library, this CD has to be re-scanned, because the meta-data has been changed, and what is displayed in the player may not be accurate, nor current.

When the daylight saving time changes, adding one hour (subtracting has no effect), Windows adds also one hour to all files’ time-stamp. Consequently if you invoke the synchronization feature the “day after”, you will be amazed to see that pretty much all your library has to be refreshed! No big deal if your library is small enough, on a huge one, it could take many hours.


For this once a year event, we have a little procedure, that will add one hour to the time-stamps inside the library, mimicking Windows file system’s changes. Hence, only the truly modified will be flagged.

MusiCHI new version 5.5: Total recall & new support for m4a (Apple) format

Brain memory failure is allowed!

From now on what is loaded in your playing queue will be saved automatically in the library, so you can recall for example the song you liked so much 2 weeks ago and have no clue how to locate it, or avoiding to play the same CD over and over again because you have no idea what you did listen to; this being for the most serious pathologies.
To use Menu > View > Playing history

Mixed OS user rejoice!

The support for the Apple format has been re-written 100% with native code, now supporting true custom fields. You can still use your mac or your iWhatever to listen and edit metadata with the MusiCHI tagger. Of course you can still use the MusiCHI player as usual and benefit of superior sound and unsurpassed searches .

MusiCHI as a movie front end?

Given m4a is also a video format you could tag and archive your m4a movies too, and using the external player feature watch them with for example VLC.


We are expanding our horizons, we a giving away a blues and heavy metal flavor, thanks to some power users. One of the beauty of MusiCHI architecture is its flexibility. Being a multi library system, in addition with the concept of “flavors”, you can tailor the metadata of any musical styles, resulting in the most flexible searches.

Other goodies

Ripper: For a multi CD set with the same composer, a new file pattern: Composer\Album\CDCD number\(Track number)Title or name.

Tagger: The box set wizard got another option, to be able to record automatically the track count of a bunch of CDs, given this tag, in Flac, does not have a standard (TRACKCOUNT vs TRACKTOTAL), it can save a lot of time. Menu > Box set wizard > Set track count.

Player: The size ratio (in pixel) of the album cover displayed while a track is playing can now be modified. The default is set to 1:1 now, but can be modified (one user favors 509:491)


For the users interested we have a client server version of MusiCHI,  which needs 2 windows machines.
A thin server: you can use an old tired laptop/desktop (although if possible silent) solely used and optimized for sound reproduction.
A thicker client:  that will perform all the searches in your lib, without interfering with the playing. A semi-powerful laptop or a windows tablet is ideal in this case.

A magical device to improve your DAC

If you have a DAC connected to your computer via USB, there is an industrial device that improves the sound quality  tremendously: The Intona high speed isolator,

One of the problem of the USB connection is that, besides the music, it carries all kind of noises (i.e. jitter). This little device was designed to clean the USB stream for industrial purpose, to allow among other things very fine measurements. Although it was not designed for audio, it gives amazing improvements in the music quality.

The good news is unlike some audiophile products:
– It really accomplishes what it claims
– The price is reasonable (200/300 Euros)
– No need to buy another too expensive USB cable between the PC and the Intona. But from the Intona to the DAC, do use the best USB cable you have.

BTW the Intona staff is very helpful as well.

Note: This device does not have a separate power supply, so it does not always work with DACs that are powered by the USB only.

I do not have commercial ties with this company, I just want MusiCHI users to know about it, so they can enjoy a better musical experience. It is not that often that one can find a device that does so much and does not carry the usual audiophile ridiculous price tag.

MusiCHI new version 5.1.00: Can you play this from memory?

Major feature, Memory playback

The audio quality improvement is very noticeable and it sounds amazing. The file is loaded entirely in memory first and then is played from RAM, so no electric noise pollution from the reading of the disk nor another process (the reading of the disk) competing with the process of playing. To enable Main menu > Settings > Audio > Memory playback

Hiding the mini player

Some users wanted the ability to have the player to behave like a normal windows application when minimized, to collapse to the bottom task bar, without showing the mini player. Best of both world, it is very easy to switch between modes. Main menu > Settings , check or un-check hide mini player.

Play list enhancements

  1. You can add the content of selected tracks in the playing queue to an existing playlist. Why is it useful? if you had created a playlist “My favorite arias” and you are listening to an opera, if you really like a few tracks, just select them, 2nd option “Add to a play list” after clicking the playlist toolbar button.  So you can grow your play list over time with minimum efforts.
  2. Some audio optimizer do disable the drag and drop feature of windows, preventing to add music from the windows explorer into the playing queue with the mouse. Tracks can be added using the 6th option “Pick tracks to add to playing queue” after clicking the playlist toolbar button.


MusiCHI new version 5.0.20: Views and generic support for external players

What are “views”?

With this version you can save and retrieve cascading order of the columns with optionally a filter on it. An example will make obvious why it is a nice feature. First here is a screenshot of my most used columns arrangement for the MusiCHI player [aka the Default].


Let’s assume I want to have every week-end a breakfast with baroque oboe concertos as a musical background. To make the best selection I would have to move my columns around this way (this picture) and then decide on the composer(s) I want for the event (Note that I switched to composition view).


I can save this view by clicking the monitor icon, pick “Save current view” and fill up a short description, so next week-end I can get to my favorite breakfast selection right away.


And because, I did the same for my default screen I can get back to it in 3 clicks. The monitor icon, “Recover view”, select item I want by moving the bar on the list [NOT the check box, see below] and click “Select”.


Needless to say, you can save as many columns arrangement as you want: Being a J.S Bach piano fan, I have this as a saved view.

To delete unused views, then check the line you want out and and click “Delete”.
You can also see the available views if you click on the “Saved views” button before saving a new one.

External players

Before we did support only foobar, now you can pretty much use any players you want as long as they can load a playlist upon opening.
