I have managed to get the Samplerbox to work. It's amazing how in 30 mins I had it working. What I want to ask is: How can I change the booting audio device from the horribli RasPi audio output to my USB device? can I modify the python file on my Mac? Or can I do it with a few magical lines of code on the RasPi itself?

1) hookup a monitor via HDMI and a keyboard and boot the pi or
2) hookup the pi to a wired network, find out the IP-adres (in your router?) and SSH to the pi on your Mac.
Login with loginname root and passwd root
remount the filesystem in read-write mode with
mount -o remount,rw /
Then you can edit the script with
on one of the first lines you find
AUDIO_DEVICE_ID = 0 # change this number to use another soundcard
change it and save and close the editor by pressing CTRL-x and y
restart samplerbox by typing
systemctl restart samplerbox
When it works reboot the pi by typing

Thanks for your reply. However when I write the line to open the python script an empty screen pops up. Saying File: Samplerbox/samplerbox.py on top and the usual ^G Get Help, ^X Exit at the bottom. Any help?
