Enhanced of the infrared input.

Added a new folder tag [WHL] (play while), which means that the folder plays as long as the logical input is activated.

Added the ability to combine gradually the inputs.
Improved the boot time and the triggering times.
Removed a slight stutter effect at the beginning of the playback of some MP3 files.
Fixed a bug that prevents execution of folder tags [RLxy] or [RSxxx] when tags [DT] or [Jxxx] are used on files of the folder, or when an infrared command or an RS-232 command stop the folder playing.
Fixed a bug that gets some wrong parameters despite the configuration file config.txt after the wake up of the player in energy saving mode.
Fixed various bugs in the management of the volume tags [V+xx] and [V-xx].
Fixed a bug in the folder tag [RET], which was ignored.

Installation

The logic and functionality of the player are defined with an internal program called firmware. This program may evolve to bring new features, to change the behavior of the player, or to fix issues. The firmware can be updated or replaced by following these instructions:

Download the firmware from our web site.
Make sure that the SD card is properly formatted in FAT32 (USB flash drives are not supported).
Copy the file MPMK2.bin at the root of the SD card.
Eject the SD card with the ejection process of your operating system.
Switch off the player.
Insert the SD card in the player and switch it on. Do not remove the SD card or do not turn off the player until the operation is completed. Wait until the player reboots completely.
At this time, the firmware update is over. The player can be switched off and the SD card removed.

Note: The firmware update has to be done with an SD memory card. The update is not supported with a USB flash drive.

Known issues

The read and write performance of the USB flash drives is lower than the SD/SDHC cards. If a large quantity of audio files need to be played, the boot time can be longer. In this case, it is recommended to use a SD/SDHC card instead a USB flash drive.
