I have the same problem, in studio one I want to edit envoloppes, set it to the three parameters set it on write. The patterns on my spark i have drag and dropped into studio one. Set the spark on host with a empty pattern selected. When is i press record on studio one the spark starts it records my midi on the fx pad but when i play back I dont hear nothing, also i set the parameters from write back to read.
Also how do I record the roller function in my DAW??
