I just got my Minibrute last week and it's friggin' amazing!
However, I've noted two issues with it and I wonder if they might be able to be resolved with some kind of calibration that is not available on the back of the unit, but perhaps resides on the main board inside...
1) Pulse width - On my Mini, when the pulse width knob is at 50%, it's actually quite a bit off. I need to turn the knob to about the 10 o'clock position to get a 50% square that matches the tone of the sub osc.
2) Pitch bend range - Works great on the synth itself, but when I control other synths over midi, what is a whole tone on the MB is like a quarter tone on any connected digital synth. It'd be great if they were the same in case I'd like to layer it up or control something else from the MB's keyboard.
Thanks again for a great sounding, great feeling instrument at a killer price! Love my Mini!!
