Maybe I have a bad synth?

So I’ve had it for a few weeks now and no matter what I do, it always glitches and doesn’t play anything or just gives me static. It’s on firmware 1.0.1 and init works but even with three ACD synths all with a single voice it glitches out when I press the keys quickly. Like it doesn’t see other keys or it thinks it’s being pressed maybe even if it’s not? Maybe I have a bad unit? Thoughts?
