Thanks a lot!
I tested this. And the sound is very linear until the Decay tail goes into the next trig.
You can kind of hear it in the video even though the volume is quite low.
It kind of sounds like some trigs have a P-locked lowpass-filter with a 50% probability. It’s pretty subtle.
If I lower the decay of the initial trig with a P-lock. It goes away.
It does sound pretty nice and dynamic. But to an electronics noob it seems odd that it seems to happen randomly. Do you recognize this?
Explored this further on both BT and HT.
It turns out that it depends on the pitch of the drum. Certain pitches are not affected, others have a predictable change, and on certain pitches the affected notes are random 
Is there any update to this? I have noticed the same problem here with my LT in my new Projekt. No LFO or something else what could have an influance on the pure tom sound is activated. The tom is very inconsistent. With shortening the decay is a bit better but still present.
Ok it is analog and works for toms, but for bass sound the random sound is very anoying.
