christian, i do not think it would be necessary to build a totally new organ interface from scratch. maybe you also read my suggestions i posted earlier. the implementation of my so-called "force-all-matrix-cells-to-parallel-cells-checkbox" and enabling/disabling of individual cells via midi controller would absolutely do the job.
i really donĀ“t need any fancy skins or graphical representations of "zugriegel". i just would like to have more intuitive access to the stops.
or did you mean that the current vi is not capable of playing more than - say for example - 100 streams (10 sounding keys/pedals multiplied by 10 stops) simultaneously? then this is a different "game of ball" (quoting DG).
