Default Roland V-Drums triggers double notes

Greetings drummers,

this is my first post in this forum and some things could be out of place, please just tell me.

So, I bought already used Roland TD4 on ebay 2 weeks ago. I'm a guitarist from nature, but nevertheless I always wanted to drum and it's been a blast and I want to continue to lern to play drums :)

Short explanation is pretty simple.
If you want it to get complicated read the status from Midi Monitor.

Anyhow, even I'm a bit advanced in using audio plugins for the most purposes and I had my share with midi and so on, I'm having trouble to understand the nature of the problem I'm having with my TD4:

Pads used: HH, Ride
Plugins/modules: TD4, Superior Drummer, NI's Modern Drummer

Error: HH and Ride are sending a double hit by one shot/ hit. (edge only issue) 1st hit (intended) - edge. 2nd hit - bow.

Please look for the possible solution I've reasoned out below first!

I can see the double hit on the display of the TD4.
I can see the double hit in SD/MD.
I can see the double hit using MIDI Monitor by Snoize (you can skeep this)

I recieve following notes (the number at the end is the velocity):

HH Pad Example:

HH closed (pedal) / 127
HH bow F#1 (note on/off) / 127
HH edge A# / 127

HH open (pedal) / 0
HH bow A#1 / 127
HH edge D0 / 127

Sofar so good hitting the HH just once, but then I hit the HH (edge only issue) repeatedly (1/8 for instance) then we have:

HH closed
HH edge A# / 127, F#1 / 5
HH edge A# / 127, F#1 / 10
HH edge A# / 127, F#1 / 9
HH edge A# / 127, F#1 / 12
... and so on. Happening sporadically!
At the same time TD4-module (display) jumps between 46 (A#2) and 26 (D1). The same is with the Open HH and Ride, without clastering you with the status messages again. But if you need those - no problem.


At first I though it would be SD, MD fault, but after listening closely TD4 plays the double hit as well just very quietly. So, only after playing SD/MD I could hear the double hit.

Could be something physicaly broken? Like the pads by overusing or the TD4-module itself?
Do I have to configure something I still don't know of?

Ok, possible cause: I exchanged the cords between Ride (right hand side) and Crash (left hand side) between eachother and as the matter of fact Crash is no having the issue.

Ok, question to the possible cause: Does it seem right to you, is it a common issue and can it be fixed before running off and buying new cymbal and hh-pads?

I hope all the evil happening because I'm a guitarist :D , but I maybe you could help me anyway. O:)
