Installation

• Install latest Raspberry Pi OS Lite 64 bit. I recommend rpi imager that allows to configure Wi–Fi (network ID and password) and SSH (enable ssh and set username/password). Also assign host name loop.
• Connect via ssh to rpi box and run commands shown below. Here r1.1.5.zip – is the version to install. Find out the latest version name on the project website.

ssh pi@loop.local
sudo apt install libportaudio2
wget -O ~/pepelats.zip https://github.com/slmnv5/pepelats/archive/refs/tags/r1.1.5.zip
# to get the latest not released version use line below
# wget -O ~/pepelats.zip https://github.com/slmnv5/pepelats/raw/refs/heads/main/pepelats.zip
unzip ~/pepelats.zip -d ~/pepelats

• To enable auto start edit one file as shown below.

# command to edit file
nano ~/.bashrc
# one line to add at the end
~/pepelats/loop.sh

The looper shows status on the web page: http://loop.local:8000 This page allows you to edit configuration files of the looper and see messages in log files. Sample configuration is accessible in starting page, use it as example to modify your personal configuration.
