Pi-Organ-Synth Installation and User Guide

The instructions here telll you how to install and get started using Pi-Organ-Synth on the Raspberry Pi 3B+. First, you should have downloaded the binary from our store at the link above.

Choose an Audio Output Device

Pi-Organ-Synth makes it easy to set up your audio card correctly. Use the drop-down menu of available audio output devices. In the example below, you can see the built-in Raspberry-Pi audio device (called "bcm2835") as well as a device labeled "USB" that is an external sound card. Choose one of these to get started. Pi-Organ-Synth does its best to set the audio parameters correctly.



Choose a MIDI Input Device

Selecting a MIDI Controller input to use with Pi-Organ-Synth is easy too! Use the drop-down menu in the [MIDI] section to view your available inputs. In the example below, we can see a lot of MIDI devices! The ones we are interested in are the "Launchkey 25 MIDI 1" and the "Numark ORBIT". In our example, we're going to use our Launchkey 25 key MIDI controller.



Start Playing!

That should be enough to get you playing sounds on your Raspberry Pi! Make sure you have speakers or headphones connected to your Raspberry Pi output jack, or that your soundcard is turned on if you are using an external USB audio device.

And Have Fun!
