I’d love to see the ability to set a default DSP setting. I have many “standard” albums. They all use the same profile. But, I have a few “oddball” albums at different rates and channel counts, that use different DSP settings (VST plugin for Auro 3D, channel routing for 10 channels or 12, etc…). A default would be spectacular and help me listen to more of my “oddball” albums that I often skip because I don’t want to load different DSP settings.
Walking over to my PC to adjust settings, versus using iPad for playback is a pain, and over the course of a century those extra steps can really add up :~)
