Multisampler Confusion

I am trying to use LSP Multi-Sampler for drums editing. I have no idea what is going on.

I was adding notes to the grid and then suddenly the whole thing just got messy. I am 135% sure that I am adding notes to the correct note, with the correct sampler and the correct velocity and the correct everything. Look at these nodes, side by side. One plays, the other doesn’t. Even the tooltip shows one note as being “Bass Drum” the other as being “C2”.


How does one note go through channel 10 and the other channel 1? What did I accidentally change here?

Did you enter all the notes using the same source?

What was the “Channel” drop-down set to as you entered the notes?
That is the thing that sets the channel number when you’re entering notes in internal-edit mode.
