Hihat pedal affects snare midi note

[Kokomo]

Hi!

I just built a DIY Hihat-cymbal from one of those cheap plastic 14" cymbals and a linear Hall-sensor based controller. It's all mounted on a standard hihat stand. After reversing the signal in MDM and adjusting the low and high values I get a perfect foot-controller as one would expect. The problem is that the level of the foot controller changes the Midi note of my snare drum. Let me give you an example:
1) If the foot controller is open/not pressed down I get my normal snare behaviour -> upon a snare hit it shows "F#-1" in the raw midi output in MDM -> snare sound is played.
2) When I press the foot controller down a bit, say 20% or more, my snare starts playing hihat sounds. -> upon a snare hit I read "F# 2" in the raw midi output in MDM, which in fact is the hihat Trigger -> hihat sound is played.

Can anyone explain this behaviour? I don't see how the foot controller can influence the midi note of my snare drum.
I'm running the STM32F103RCT6 (FW 20130210) Megadrum to my RME UCX (Midi 1) and then into SD2 toontrack Solo 64 on a Win7 64-bit machine.

Thanks for your help,

Chris

Edit: forgot to mention some settings: Hihat pedal settings:

Type = FootContr
Curve = Linear Custom1
Hihat input = 4 (foot controller is jack 1)
Only Reverse levels is checked
Notes are all set to 42 (F# 2)

Set HiHat input back to its default value to 2.

Hi!

You mean even if the HiHat cymbal is plugged into Jack 4? I will try and report back when I get a chance.

Thanks for the help,

What input did you connect your snare to?
