Hi Frank

Thanks for helping me think this through. Yes, if you use an external module for both accompaniment and lead, then a merge is required somewhere (with the exception you noted). I would prefer not merging at the computer. Note that merging is only necessary when one module is used for both accompaniment and for lead. If the funtions are split between modules (or between a module and the keyboard) no merging is required. Where merging is required, this can be performed in some cases by the keyboard itself (e.g., my Roland A-50) and in some cases by the module (I will try to get some models that permit this).

Given your warning, I would limit the computer to only one function, and that is converting chordal inputs to autoaccompaniment. I guess it is best to let this new field mature some before trying to combine programs and functions, especially from different manufacturers.
