Easiest method to create styles from scratch

[Henni]

Hi all,

I've modified many a Yamaha style over the years, but never made any from scratch. Now I intend to do just that. Please help me to find the easiest way. Problem mostly lies in the CASM - I think...

Can I maybe use a more or less similar style, unpack with MixMaster and just completely replace the required midi tracks with those of my own. Will the style then assemble correct with the correct CASM. Which program/s do you suggest I use for this?

Please help me to get started. I should grasp quickly.

Thanks,

Henni
