Modular synth fault finding ...

Suggestions harvested from modwiggler:

you need a quiet power supply. low ripple. upgrade the power supply, upgrade the bus board.
you need low impedance from the power supply to every module.
you need to have a ground the does not move at all. by move, I mean the voltage at ground is no different from ground anywhere else in the system. differences in electrical potential, especially differences that change rapidly over time, are the source of the noise.
there are two kinds of noise, common mode, and differential mode. anything can happen in a synthesizer. the voltage ref is also a power rail.^[1]
