I've had my minibrute for a little over a month and two days ago at band practice, I plugged it in and turned it on and there was no sound. Upon further investigation, it was putting out a signal, but the keys just made a short, percussive sound like a digital tap. It still sends midi signal to my computer, but the analog part of isn't working. I have tried other power sources, different outlets, different cables, pretty much everything. I keep it in a case and it rides in the car with us when we travel, never dropped, no physical damage. I'm a little disheartened that my brand new product isn't functioning in under 60 days.
