I was quite disappointed when the Thor iPad app with presets made by Patchmanmusic sounded so much better than my Nord Micro Modular with my Midi wind controller (WX5)! But I’ll have to live with it. The response with Thor is amazing, so much better than the Nord… In the end I am happy 
The only thing is to get a reliable connection from the iPad lightning to MIDI. Tried several things and key seems to be to have the original apple cables.
