the original composer would need to be 2 x 6 patterns each with 1 intro and ending etc to match up to kn2000 spec. Also if the maximum no of measures allowed in each pattern was different the information will be in the wrong place.

this works with machines of the same generation, using similar internal chips and architecture, you need to be sure the 2000 is the correct nearest equivalent to try, it can be a process of trial and error with no guaranteed results because the formats were never designed to be crossed over like this. However in the past when I collected every pattern from every machine the majority could be converted to some form of usefulness.
