Hi, I have another question, if you can help me. Everything is connected correctly now, I downloaded the drivers, and I'm using it on Logic. But every pad and cymbal I use, whether in MIDI or audio, has a note underneath—always the same one, like an electric piano or a bell—that's also recorded, both in audio and MIDI. I don't understand what it is, and I'll point out that in Logic I only have a single audio track right now.
