I'm using a very small stack of MIDI equipment (Roland MT32 and SC55-mkII) and they each use their own power supply (brick).
Can I use a single (larger) power supply with a splitter or is this a bad idea? I've also seen USB-to-9v adapters which look useful for powering this equipment. (I know the polarity on the Roland equipment barrel jack is reversed from normal)
I've seen people with video game consoles try to share a single power supply and lots of people don't recommend it due to video/sound issues, etc.
