I would like to describe small solution and a powerful utility of the latest pic firmware.
This is a small demostration to show you how to use MegadrumManager ( to change parameters etc ) and recording midi mapping with your sampleVst in a daw at the SAME time ( in my case Cubase )
The combination facilitates the configuration of pad, specially to setting the dualMidpoint/dualmidWith for dual zone pad, see more crosstalks error, triggering suppression , what happen for the multi switch of cymbal to take 2or 3 zone etc.

In my case i've opened first the megadrum manager--->options---> select "megadrum usb"
Click " Open Midi" and "GetAll" to load from MD all parameters
After this i've open the daw, go to midi setting---> disable the Midi Called "megadrum usb" ( already in use ) , select instead " Megadrum USB 2 " and click ok.
With this configuration you can see all the midi log from your MD and recording the session at the same time.
I realy like this solution, I hope this can be of help to resolve all the errors midi.
