HI Diki

What you are asking for is for Dan to design his arranger software to work with multiple sound engines, and quite honestly this would take a team of dedicated engineer’s ages to achieve, (Not forgetting the constant updates that would be required as manufactures updated their sound engines) and to be quite honest is not a practical solution.

If you only have 1 sound engine to work with, then the time to balance everything up is considerably reduced, and it becomes like a hardware arranger (IE fully integrated) rather than a universal arranger. (Jack of all trades, master of none)

Regarding loading voices when changing styles, then this is a non-issue, as most hardware arrangers have about 1000 voices, and that amount can easily be loaded into memory at start up, (Ram is cheap, and SSD are dropping in price so fast that speed and storage will have little relevance)
