Designing a synth bipolar PSU inspired by Doepfer's A-100 PSU3 (i.imgur.com)

I’m planning to make a modular synth from scratch, but I need to start with the PSU. Do you see any issues with this schematic?...

The linear regulators are still there. It’s the rectifier that gets replaced. I guess the main difference in the power side is the high frequency noise of the switching PSUs vs the low frequency ripple of the rectifier, I’m not 100% sure if 7x12s are immune to them at least at audio frequencies.
