What I found out additionally. When the module has only power connected, it works perfectly according to the built-in LCD display - no noise, but the pads trigger the signal as expected. But when I connect to my mac and launch MegaDrumManager or any other midi software (Addictive drums, built-in Midi Configurator), it starts flooding. On Win machine module starts flooding right after I connect to the USB. Perhaps it depends on when the OS tries to initialize the MIDI device.
Also I tried to change the gain (set to 2) and threshold (set to 70) on the specific pad in different combinations, finally the noise disappeared, but the pad has become very insensitive.
Understood, it seems you have a pretty severe case of abhoritant noise being tranmitted just by the interaction between your computer(s) and Megadrum. It's not uncommon but it does seem to vary by person / setup. I suspect it's because the power delivery via USB is just too simplistic.
For example, I have the exact same issue as you but I get it in short bursts, not sustained noise:

The gain directly affects how much the noise is boosted, so I've worked with the problem, to a point where I only have my rim piezos go spastic every so often.
You should be able to find the balance too if you continue tweaking, you just won't be able to have as sensitive pads.
The secondly solution is to use a MIDI cable, to an audio interface, and run Megadrum from external power. Less elegant, but less problematic with noise, probably. I believe carrying MIDI messages inside +5 volts is the real issue.
