OK Mike I understood the channel number makes sense with sysex. Thanks.
Yes, I mean a pause between MIDI commands.

And thanks again for Mobilesheets and your listening to users  

Mike, I think I found were is the problem :
Image 1 - The Wall - midi datas created with mobilesheets PRO : sysex works perfectly
Image 2 - Sweet Home Chicago - miidi datas created with companion PRO : sysex don't works correctly. Nothing happend.
As can be seen on the images sysex is exactly the same on both.
If I modify with mobilesheets the data sysex it does not still work.
If I delete the line of sysex and if I write again the data sysex, it works.

Maybe this can help you. Or let know where is the datas I will check if datas is equals or not.
