Hi Gary , thanks so much for sharing this information with us all.
I'm using with my acoustic midi accordion via music tech transmitter and receiver a PSR3000 keyboard that has been made specially for me into a module ....I'm really enjoying the freedom this set up allows me to walk /stroll ...no midi cable attached to the accordion !! I'm really impressed by the Yamaha operating setup and the ease of use of the registrations !!and the great sounds and the vast amount of styles available .
Question ;- is it possible to save a particular multi pad setting into a registration ....ie piano boogie woogie player ?
