Absolutely agree with BOGDAN. 100.Percent.
YEM's biggest 'non problem"' is that users don't acquaint themselves with how it works BEFORE starting to install packs or new packs. Then they make a mess of it, and blame the program.
It's not the program. It's that they can't be bothered spending an hour say checking out some YouTube or reading HOW IT WORKS.
So long as you have the latest version.
Re-install any existing packs that are already on there, so if you have 3 packs already and you want to install another 4 then you will actually install 7 packs.
Have the keyboard initialisation data. and click on target instrument, then it really isn't difficult.
But you CANNOT take short cuts with it. You WILL come unstuck if you do.
Allow plenty of time to install the packs, follow the instructions which you will have written down...... You WILL do that, won't you.... and it really is easy.
Yes, it's a clunky program.
Yes, we reckon we could all write a better one! (Nobody has yet!)
Just get all the info you can BEFORE starting, and you'll truthfully wonder what all the fuss is about.
You won't lose ANYTHING by using YEM.
