Something I would like, to speed-up EM programming, is an auto-learning feature.
For example, click Learn, and play all the keyswitches used to select the articulation you are programming. They will immediately become separate elements of the EM item.
You mean, you want to play a note on your MIDI device and use that as the way to specify the key switches for the currently selected base or add-on switch?
Exactly this, Daniel. Only, it would not be only a single keyswitch, but as many as are needed for the selected base or add-on switch.
For example, VSL articulations often require up to four or five notes used as keyswitches at the same time. The first one selects the main category, the second one the variation, the third one the vibrato, and so on.
