Note detection and simultaneous notes

Hi there, I'm trying to work on a simple monophonic drum patch, that behaves kind of like an analog drum module. I'm sending it midi from the drum16 sequencer.

I wanted to be able to set which MIDI note triggers the drum from the GUI, instead of using the sel.note gate object. I couldn't get it working though! The events got all messed up and velocities from a different midi note were getting jumbled up with the ones from the note I was trying to work with.

I used the event watcher, and the "simultaneous" notes were all sent in a logical order, and I was trying to parse it all, but couldn't seem to get it to work.

Now that I'm all mixed up on this, I really want to figure it out! Has anyone else dealt with this issue?

I've tried sending it midi from something besides drum16 (I used numerology), and had the same issue, so I don't think it's the sequencer.

Thanks!
