Its the normal noise Very low when you have a Big patch and push the system. So i Will try another psu until om done with my new case with no busboard just high end quiet stabile power with rails ect that i want. Im making a 3D sketch on the case now, I want my keystep pro to be foldable under the case and another small box you can fold out that has shorter patch cables in m.m, and i want some modules on the back and sides on the case to.
I have so many modules now and will build a real case and not have to replace modules with ribbon cables which I think are pretty bad if you are changing modules all the time, because i do not want to buy a new case. so I will build my own where power and everything should be top notch before I buy new modules hehe. I mix digital and analog modules on the same board and have ribbon cables of different quality. and some modules are noise sensitive, so it probably depends on more than just power supply. but I still want to test. always good to have a power supply extra at least;) if you want to build a smaller case.
