Led issue on LK-S450 with MIDIs files (Chordana related)


Aug

Recommended Posts

Hello,

I recently bought the lk-S450 and downloaded the Chordana app to transfer songs in the piano so i downloaded many midi files but not from midiworld.com,

but from youtube where people were giving free midi files and those files really work on the app, i can see both hands playing but when i transfer it to the piano with a cable the piano gets it, however when i play lesson mode with both hands only the led from the left hand/left part are coloured, the right part is playing itself without waiting for me to play any key, so i tried to see if it was my files by transfering predowloaded Chordana song in the piano and in this case both hand are coloured so i think this might be a problem with the midi files but i dont really know that much about this kind of files so if anyone knows how to make it work please tell me.

(the midi files i downloaded are from kesh's youtube channel if anyone wanna see those files)

Thank you

Usually key lighting issues with MIDI files are due to how the files are arranged as far instrument parts.  The keyboard expects left and right hand parts to be two separate tracks. You'll need to check the MIDI files for that by playing them and finding which part number is left and which is right.  Sometimes the files will place both parts together making it impossible to separate them.   Hopefully this helps.

Thanks you for your answer, i juste wanted to add that when i disable the left hand on chordana and then transfer, only this part is lighted up.

And if the problem comes from my midi files do you know how to make midi files that are compatible with this piano ?

Thank you

Yes i use this one and i wanted to add that when i play a song that i dowloaded on the app with a midi file from external source, and when its linked to my piano both part are lighted up but it is when i transfer the song and then disconnect my piano from the app that no part are lighting up.

Thanks for your answer

LK-S450 is not compatible with the transfer function.  Note the list of compatible models on that page. 

 

To transfer MIDI files and specify left and right hand parts, you will need to follow the instructions on page EN 80 of the LK-S450 user manual titled "increasing selection of user songs".

Thank you,

I read this page on this url: https://support.casio.com/storage/fr/manual/pdf/EN/008/LKS450_usersguide_EN.pdf

If this is the right page then i don't know how this can help me because i think the problem comes from the fact that my midi file has only one track and that is maybe why it only works for the left part so i wanted to know if you knew how to make midi files able to have 2 part so it may work. 

Thanks

Unfortunately it is often difficult to split a single part into 2 parts.  Sometimes left and right hand parts can use the same keys depending on the song.  I'm not aware of any software that can do this automatically.  You can manually separate the notes using DAW software and the piano roll view copy and paste functions.  It would be tedious and takes some understanding of music to work with note events in a piano roll view.

Okay thanks for your help!

I have dowloaded an app named MuseCore to dowload the midi files and get their partitions and i know pretty much nothing about how to read these sheets but i can see that there seems to be the upper line that is for the highest notes and the down part seems to be for the low notes so maybe i will try to find something to do with this.
