There is just so many pieces that are redundant. For example - the drums and patterns in the i30 are equal to the is5m - the PA1xPro has all the sounds from the O1W ... it's just too much bulk for no good reason. Years ago ... you needed all the modules, but today's gear has the bells and whistles built in. This guy is such a great player that he could use a Casio and make it sound like the Philly Pops. He's just reluctant to change. I'll convince him ... someday.
