I'm working on some recording for a Christmas project, and I'm pretty new to the whole producing thing. I'm really struggling with a trumpet sound (MIDI) where I want it to be loud, but when the volume is turned up it gets--on the high frequencies-- really "squealy", if you know what I mean--just really unpleasant to listen to. It's not a clipping problem, really, and I like the way the trumpets are mixed with the other stuff when it's on a lower volume. But I want to make it sound good at all volumes, without changing the master volume. Is there anything I can do to tweak that high-frequency stuff without just compressing it more? Because, actually, compressing it isn't doing a whole lot for this.
