Update: I just noticed a fun thing, changing the pitch of the drum inside of EZD2 does NOT change the pitch of its hiss/noise. But if you solo that drum’s channel, the hiss is still there! So maybe the samples are fine and the noise thing is related to the internal sound engine… I hope they look into it
I’m often using Core Audio with built-in audio on both my current MBP and the previous one for Support related work and have never experienced any hiss, especially not what you’re describing. If you would be using EZdrummer 2 as a plugin in a DAW, I would guess that you had some kind of plugin in the audio path after EZdrummer 2. But you’re using it Standalone, so that’s strange.
