Bass Notes Cutting Out?

Please forgive me if this is a rookie question. I’m having a problem with bass notes cutting each other out unwanted. If I have eight tracks all going to the same out, with the same bass sample on all, and choked in the same group I can play them slowly, however my problem is when I move to the next pad quickly sometimes that pad does not play. For example I hit A4 and quickly hit A5 after it. A5 chokes A4 however A5 does not play. This is intermittent and is unpredictable….I’ve tried to play with the envelopes and different quantization with no luck…does this happen to anyone else? I don’t believe this is update related as the same thing would happen in the MPC but I never figured it out there either. It’s probably SUPER simple but I’m out of ideas…anyone know the remedy?
