MegaDrum Lite, kick input and hi-hat controller problem

[hajdek777]

Hi all,
Finally I managed to complete my Lite MegaDrum module! I have installed MDManager on my mac, I uploaded the latest firmware and I set MD midi driver with my Kontakt application. Everything seems to work out of the box, except first 2inputs: hi-hat control and kick. I think that the kick input should work as the other inputs (its only one mono channel), but I had zero activity when I plugged pads or cymbals. Same with hi-hat controller, nothing, i try pot and foot cont. option, low and hi impedance (i made switch like in 32MD module) and nothing. I have alesis 8' dual trigger pads (single for kick) and roland dual zone (piezo/switch) cymbals, simple switch on/off hi-hat pedal and alesis realhat controller (the one I like to use), all working fine with my XMdrum module. I cant find anything similar as my problem on the forum so I need a little help.
Regards

First, I would suggest you to check electrical continuity from the the first input pin on the board to the kick piezo and from the Low impedance HiHat controller input pin on the board to the HiHat pedal switch. Also check continuity from ground pins on the board to the kick piezo and to the HiHat pedal switch.

all conection are fine, tripple checked, maybe its something with MD system setup, I havent change anything yet, but as I said the rest of the inputs are fire up on the lcd screen and on the MD manager on my mac.

It should work with default settings. Have you changed any settings?
Since the problem is with the kick input and the HiHat pedal input I suspect that you may have connected them in wrong order, e.g. the kick piezo to the low or high impedance HiHat pedal input pin, and HiHat switch to the kick input pin. Take a picture of the board with the flat cable connected and show on the photo which wire you connected the kick piezo to and which wire you connected the HiHat switch to.

So, I haven't changed anything in the system setup, all default

I marked last 4 pins/wires:
red color - pin 40, go to ring/middle connector in jack socket
full blue - pin 39, go in to left side connector on the 2way switch
dashed blue - pin 38, go in to right side connector on the 2way switch
green - pin 37, go it to tip connector in second jack socket (kick input)

the middle 2way switch connector go by red wire in to tip connector on the first jack socket (hi-Hat contr.)

To exclude everything in between, can you connect a piezo directly to pins 37 and 15 and then tap the piezo?
