What is patchOS?

patchOS is an operating system for the Raspberry PI 4 that makes two modular synths patchable over the internet.

Requirements

• Raspberry PI 4
• 8GB+ SD card
• Expert Sleepers ES-8 module

How to install

1. Grab the latest release of patchOS
2. Use etcher to burn patchOS to the SD card
3. Boot your Raspberry PI with the new patchOS SD card

How to use

patchOS is controlled via a simple web interface.
It's best to use your phone for this.
Open your web bowser and navigate to http://patchos.local

Special note for Android user

Android doesen't support mDNS in the browser. You will therefore not be able to connect to http://patchos.local.

Thankfully there is an easy fix by installing a network discovery app.
A good suggestion is BonjourBrowser

Install the app and it will find patchOS control panel for you.

If you are behind a NAT or a firewall

patchOS uses UDP port 4464 to stream audio.
If you are behind a NAT router or a firewall you need to forward UDP port 4464 to the IP of http://patchos.local.
This is done by logging into your internet modem/router and finding the NAT or firewall settings.

Notes

patchOS is an experiment; not a product.
