I’ve been given that advice & it helps a bit but the H90 is still one of the noisiest (& most expensive) pieces of gear in the studio.
I don’t have the USB issue with any of my USB synths – Waldorf, Korg, Behringer, Arturia.. I’ve loads of USB devices even Boss USB fx pedals – are dead quiet.
My question still stands – I think these units need a better power supply.
