Hi again OGPrinnny,
If you here two different instruments on a midi(lets ay a guitar and a piano sound) the channels have to be separated.
Channel 1 has got the piano sound and channel 2 has got the guitar sound.
Same with all midi songs that you can hear drums,bass,pianos strings etc.
They have up to 16 different midi channels.
If you hear just a piano sound,unfortunately you have to test it on the keyboard or on a midi notation program.
MuseScore3 is also displaying the midi channels.You will see that is displaying just one midi channel for the song.
I have used Fl Studio to separate the notes for left and right hand.
It is not a free program,but as I said all midi notation programs has a feature to copy-paste and delete notes but right now I am not familiar on how to do it on an easy way with Musescore or any other free program.
Here is a video I have made of how "Synthesia" is showing, just like the s970,that there is only one channel of the above midi song:
