Karaoke files often have a ".KAR" file extension, but they're just MIDI song files that include additional types of messages for the lyrics and other information, so it's okay to rename the file to change the file extension from ".KAR" to ".MID." (2) The MIDI song files must have a ".MID" file extension. Also, don't remove the thumb drive while the keyboard is trying to read from it or write to it. Note that when you insert a thumb drive into the USB TO DEVICE port on the back of the keyboard, you must wait patiently for the "USB" indicator in the upper left corner of the LCD screen to stop blinking before you try to access the data on the thumb drive. All you can do is try a given thumb drive to see if it will work. Most USB 2.x thumb drives should work, but some brands might not be compatible, and USB 3.0 thumb drives definitely won't work. (1) Not all USB thumb drives will work with the keyboard. There are a few important things to be aware of: Additionally, you can toggle some of the tracks on and off, repeat a particular portion of the song (although this inserts an extra "count-off" measure of metronome ticks each time the loop begins), or use the other Song controls, as described on page 25 of the manual. You can also change the tempo, adjust the volume, or change the voice used for the first track (i.e., MIDI channel 1), as described on page 47 of the manual. Once you've selected the song you want to play, all you have to do is press the PLAY button to start the playback. When browsing through the list of songs, the built-in songs will be listed first (songs 001 through 110), followed by the 10 user song recordings (songs 111 through 120), then any songs which have been transferred to the internal flash memory (song 121 and up), and finally any songs on the USB thumb drive (beginning either with song 121 or some higher number, depending on whether any songs are in the internal flash memory). In either case, you don't have to "load" MIDI song files to play them- you simply press the SONG button to enter the Song mode, then use the various controls (the big dial, the number keys, the CATEGORY "up" and "down" keys, the "plus" and "minus" keys, or some combination of these methods) to select the song you want to play. (2) You can copy MIDI song files to a USB thumb drive and plug it into the back of the keyboard. (1) You can use the Yamaha Musicsoft Downloader (Windows) or Yamaha MusicSoft Manager (iPad) to transfer MIDI song files to the keyboard's internal flash memory. There are two ways to play MIDI song files on the PSR-I455 and similar models:
