@Lugia I agree with your thoughts on monitoring and mastering. Right now, I'm working with a fairly limited setup and haven't invested the time to ramp up my skills and understanding in that area. Currently, I do mastering in Logic Pro X. That includes limiting, compression, EQ, stereo spread management, and normalization. For monitoring, I use Yamaha HS5's and Pioneer HDJ-X7's. The chain looks like: modular -> Scarlett audio device (input) -> laptop -> Logic Pro X. Output is through the Scarlett to monitors/headphones. I hear you about ear fatigue and also struggle with mastering for the typical case end listener. I've tried to master using 'neutral' monitors and headphones, but I'm lacking a good end result for the normal listener. It's an area where I'm looking to improve, for sure.
@GarfieldModular Thanks, glad you liked it. I hope to do more of these in hopes that others can get something out of them as I continue to learn.
