Hi , I've got 2 smac 1200 units they are great , pity technics never continued and developed this product .

All the questions you are asking are too technical for me !!
I have converted midi files to styles for the unit ,i used a conversion prog called "EMC universal conversion soft ware "it is very good !!!

Do you have the user manual for your smac ?

regards .........Giovanni

PS even though the smac is at least 12yr old it is still a very good expander /arranger I've gigged with it for years with my midi accordion !!
if you require any styles i have a lot just let me know what you are looking for !if i have it I'll e mail ....OK
