I have finally got Pisound running on a Rasp 4B. I used a generic USB charger to get it going (very noisy audio but I expected that).
Now, I intend to use it headless and with a USB MIDI controller (Bitstream 3X) plugged into one of the Pi’s usb ports, the 3X draws 400ma power.
What kind of power supply should I use to power this combo? Is there an offitial PSU that is recommended?
