Hello !!!
Yes, thank, this one works!!!
If I hit my piezo, when I press a switch, I can affect the sound like I want through this on, I can see the red LED blink...
But, I don't understand how to "choke" the sound : when I hit and press, I want the sound become silent
I'm searching in Drummanager by changing parameter one by one... Dual or 3 way Yamaha or Roland... (but Roland give a hihat sound with the switch???)
So ... could you explain to me ?
