Will it work on the Zero? There are some cheap old drum machines on the market that have nice sequencers onboard. It will be nice to fit them with some 808 and 909 samples.
This is what happens for me:
1) Write the image to the SD Card and insert it into Pi Zero.
2) Attach powered hub to Pi Zero.
3) Attach midi keyboard, USB stick with samples, usb audio interface, and keyboard/mouse to hub.
4) Attach HDMI out to monitor
5) Attach power to Pi Zero
Pi Zero LED alternates between solid and blinking, no HDMI output is present
