For those interested, here's a picture of my new trimpots installed on my duel piezo inputs. Boy was the soldering a messy PITA.

So far very pleased! Nothing is broken and it's so much better to adjust on-the-fly.
My 3-zone triggering has improved significantly, that rim-shots are a joy, now they are more reliable. TBH I think my trimpots should be in the default kit but I understand that's a lot of extra soldering for Dmitri (perhaps an optional premium?
)
I was able to do lots of experiments with variable resistance.
Key findings:
- Input 8 is indeed ridiculously hotter, it needed around 48k to bring it in-line with the rest. Nothing hot about the drum.
- Cooling all the rim piezos slightly (2-5K) helped with crosstalk (between inputs and the head piezo on the same input) even though they are very insensitive. Gain 7 and HighLevel 64 remains the best setting with Gain 8 introducing too much noise. Very dynamic even so. It's just the design of the trigger at the end of the day.
- Adjusting the trimmers had no affect on other inputs (duh) but I had to prove it to myself.
- No "crazy spontaneous self triggering" on the rims yet but I've only had it on for an hour. Point 2 might have helped.
- Tom 1 was very rim happy and there was nothing I could ever do about it in MDM, to stop the false triggering. Turn the trimpot slightly and problem solved, couldn't believe it! This was something that couldn't be calibrated out MDM.
- Still got self triggering aftertouch messages on both my cymbals. So obviously the next job will be to apply some trimpots to those inputs as well and hopefully eliminate this problem once and for all.
If I solve point 6 and if the "crazy spontaneous self triggering" never comes back, it'll be serious cause for celebration as those have been issues for years!
