The XP/JV/XV-series are MADE to be programmed. Creating the sounds you need is part of creating music on these machines. It is almost like asking why it is so hard to create good music on the XP.

When it comes to programming on the XP, it really is not that difficult. But of course, doing complex things on complex systems can never be made easy.
If you want simple, buy an accordion. Instant access to all the 4 sounds. They even sound the same anyway, so it doesn't really matter.

Just my opinion....
