Hi Diki , thanks for your very kind offer .
I'll keep it in mind .
I've always been a technics smac1200 module user midied up to my two midi /acoustic accordions and I've got a good collection of styles over the years .
I don't have the time to start from scratch with all the styles again .

On april 3rd I'm going to a presentation of the Roland BK7-M at the Pakefield organ festival in the Uk .
I'll have a much clearer idea if it will be suitable for my requirements

My friend Don Patterson has given a good write up of his findings based on his attendance of the recent Texas accordion convention ,which for me was very interesting regarding how easy it seemed to set the midi accordions up to the BK7-M .

best regards .....Giovanni
