I bought it and I barley hear sound on some keys

What app do we use on the computer?

I returned it. The pads often do a double hit, send 2 MIDI notes when I only hit it once. For every ~10 notes, there was at least one that registered as two, which is distracting to hear when playing, and leaves a mess of erroneous notes in a recording that you have to edit out afterwards. So I returned it and got a 2nd PreSonus ATOM to use to play/record my 2 analog drum machines. Besides the pads reacting poorly, it works, feels the same as the ATOM pads. The software is strange but once you figure it out, it can be used to map the pads to specific notes & MIDI channels. But if it doesn't translate what I play correctly, what good is it?

This item is amazing
