Hi,
I’ve been testing this on my ipad for a few days now. The whole concept is truly amazing and I love it. However, the app crashes erratically, not entirely but it stops my whole setup leaving a hung MIDI note. When this happens some of the other apps lose their MIDI port mappings with the UR44. My setup is Xysthesizr, Samplr, Steppolyarp all synced to Genome, also some external MIDI gear. This all runs with no problems if I turn the dspMixFx app off.
