Great that it seems to work now. Why it only works with one modulation on a Sound, I don't know unfortunately.
I agree that drawing automation curves is far more comfortable in LPX than it is in Maschine. Maybe this article helps to find out how to create curves and such: https://ask.audio/articles/logic-automation-tips-tricks
If you are using different patterns within a Sound to create the different parts in Maschine, you will not be blocked. You have endless Groups which each contain 16 Sounds which each contain 16 Patterns (or even more, I don't recall). Here's what I would do:
- Let's say you want to have 4 program changes sent over the time of a song to the KPA. Use one Sound in Group A1 and create 4 Patterns in that sound. Each pattern holds the program change MIDI message.
- Let's say furthermore that you want some Wah-automation in the 3rd part of your song. Use a second Group (B1) and again one Sound and create 1 Pattern holding the Wah-Automation to be sent to the KPA.
- Then arrange the patterns in Maschine's Song-view to create the arrangement:
