False Trigger Suppression Algorithm Single Piezo vs. Dual

[maru_engineering]

Hi Dmitri!

I found out that my problem might be related to the third zone detection algorithm... Please have a look at the attached pictures...

I didn't mention that I worked on the pad in order to reduce the ringing; see below the wave forms and the Trigger result; the second pair is a double note...

And here is the picture of the pad; I replace thestruts with aluminium ones and I used fewer of them in order to achieve monotonically decaying wave forms...

1. This is a mesh pad but you reversed DynLevel and DynTime back to low levels. Raise them.
2. It's dual zone piezo/piezo pad so don't disable 3rd zone but adjust MidPoint for best balance between head and rim hits. If you don't want to use crosstick (3rd zone notes) set MidPointWidth to 0.

I'm new to megdrum and just got my module (thanks to dimitri for fast delivery on this way ) and trying to setup my drums. After quite a while of try and error i read this topic and i was able to reproduce the effect with the swapping stereo so mono cable... No matter if i set up the pas as single or dual pad and also no matter if i disable the second input completly. I think this is something weird in the firmware, isn't it? Is it a good advise to short the ring to sleeve an 1 zone pads in order to achive better falseTrigSupp?

I think that there is something strange about this behaviour as well, but it seems I couldn't convince the master...

I reversed the polarity of the Rim Piezo and raised the Threshold for the Rim Zone in order to get some kind of compromise... In my case we're talking about the Snare so I cannot afford to supress the Rim zone completely (like using a mono cable)...
