Samplerbox in failed state

Hello,
Samplerbox won't give any sounds or show my files on the USB-stick.
I can see a failde state, but no reason for that.
This is the info I have:

root@samplerbox:~/SamplerBox# systemctl status samplerbox -l

Hi, found this one.
I had to change the defaults in samplerbox.py. They don't fit a plain raspberry, but expect a display, buttons etc :-) see below

AUDIO_DEVICE_ID = 2 # change this number to use another soundcard
SAMPLES_DIR = "/media/" # The root directory containing the sample-sets. Example: "/media/" to look for samples on a USB stick / SD card
USE_SERIALPORT_MIDI = True # Set to True to enable MIDI IN via SerialPort (e.g. RaspberryPi's GPIO UART pins)
USE_I2C_7SEGMENTDISPLAY = True # Set to True to use a 7-segment display via I2C
USE_BUTTONS = True # Set to True to use momentary buttons (connected to RaspberryPi's GPIO pins) to change preset
MAX_POLYPHONY = 80 # This can be set higher, but 80 is a safe value
