hello everyone
I for kit changes have adopted this solution:
1- save my kit in a .sd3p file (file->save as..) and so on for other kits.
2- I installed deckboard which allows me to make buttons (from the cell phone ) with which I can call up the file .sd3p
3- the kit is uploaded in 5 seconds to SD3 and I can play the new kit in my live.
plus:
for each kit I enabled the metronome with the appropriate click (drum out 1/2 and click out 3/4) with another button in deckboard I enable the play and also have the click in headphones.
