This is a post for those of you who are well schooled in the process of using SysEx midi commands.

I have used Dan's vArranger for over 5 years with my Roland A-800 Pro 61 Key controller. Within Dan's software is a method to assign functions to sliders and buttons of your choice and is very easy to use. So, my question is this: are all SysEx midi commands the same or do various devices use different SysEx commands to do the same thing?

I was wondering if my current setup on my A-800 Pro just might function properly with the Ketron SD90.
