Internal Crosstalk

[bt430]

I've got an internal crosstalk issue I can't seem to figure out. Here's what I'm doing. I've got a single piezo trigger which I'm plugging into each input to test my midi mapping. I've found that on 2 channels of the 8 I have programmed I'm triggering sounds on adjacent inputs. So 1 single mono trigger plugged into a MegaDrum trigger input is triggering sounds on 2 different channels. I've checked the programming, I've checked the source, I've messed around with crosstalk settings, fooled around with the thresholds but nothing seems to help. I'm hoping someone may be able to point me in the right direction!

Thanks!

Tapping bare piezos can trigger very high voltages and can cause false triggering on 2 adjacent inputs due to electromagnetic interference. Either disable unused inputs by setting Note to 0 or connect two piezos to both inputs.

Dimitri it's not a bare trigger. It's an acoustic snare with a quartz cone trigger. At the jack I've got a 47K resistor across the leads to cool it off. I had set all the other parameters to 0 when I was troubleshooting.

Is it a dual piezo pad? If not, disable the Rim input.

No it's not. All my drums are acoustic with one piezo trigger per drum. I don't run multiple piezos. I use real brass so I'm not running hihat or cymbal inputs. I set all the rim input notes on all the channels to 0. Is that the right way to disable them? My sound source is on MIDI channel 10 so I set the midi channel to 9 on all the unused megadrum inputs hoping maybe that would help. Don't know if this is a clue but the channels triggering are aux channels.

You can disable any input by setting the Note to 0. Are you saying that even setting Note to 0 on Aux inputs doesn't disable them and they still trigger?

[bt430]

No if I set them to 0 then nothing triggers.

Then if nothing is connected to them, just disable them.
