jOrgan Pi

The jOrgan community have been experimenting with using the Raspberry Pi for running jOrgan Fluidsynth dispositions, and with the Raspberry Pi 3's 1 Gig of RAM it has become a platform that is usable for many of the available dispositions.

So I have created a jOrgan Pi - based on Raspbian Jesse with jOrgan 3.21 beta installed, plus a good number of classical, theatre, and other dispositions.

In order to run jOrgan Pi you will need to load the image on a 16Gig micro SD card, and then run the SD card on your Raspberry Pi 3.

Download the jOrgan Pi image from:

https://mega.nz/#!Zso3xC6Q!je--LIIhvBU1jz8jmIxZf8EyY8vlxZmrcb54Y1PQzCo (size: 5.3G RAR)

This is a RAR compressed file, so you will need to decompress the image before applying it to your SD card. WinRAR or 7zip should be able to decompress the image file.

I have also created a jOrgan Pi Base (Raspberian plus Fluidsynth and jOrgan 3.21) which can be loaded on a 4Gig or larger micro SD card. You can download the image from : https://mega.nz/#!ktQkQDzC!0RDdL50MKRnkNpN0u5S8rC4ocq6YdH6suavFkBA-ZWE (size: 1.2G RAR)

See https://www.raspberrypi.org/documentation/installation/installing-images/windows.md for more information about installing the image to your SD card from Windows.

The image has been configured to use JACK as the audio system setup to use the Raspberry Pi sound device. I would advise that you add a USB sound device and configure JACK to use that device, as the native sound has a lot of hiss and is a low functioning device. If you're going to use the on-board sound card you must unmute it and turn the volume up. I would recommend that you rather purchase a cheap USB sound device and use that.

All the jOrgan dispositions have also been configured to use JACK. The VirMIDI (Virtual MIDI) device has also been added to the system.The jOrgan organs are available from the Menu, under jOrgan. They are pre-configured to use VirMidi ports - but you can use the customizer to set them to your system's MIDI.

The jOrgan Pi operating system is released under the GPL license (as it is Raspbian based). The various jOrgan dispositions are released under their own licenses (most of them are Creative Commons Non-Commercial).

Known Issue: The jOrgan installation of jOrgan Pi does not have the Soundfont Import feature working. This will be fixed in the next release.

Configuring JACK

Click on the JACK icon in the top left menu bar to make the Qjackctl (Jack Control) interface visible. Click on Setup. Select your sound card in the Interface drop down and configure the Frames/Period and Periods/Buffer to a lower latency setting that the default sound card. The Frames/Period value should be around 128 or 256 (512 is also usable).

Once the changes have been made, click on Save. Then click on Cancel to close this screen. on the Qjackctl main screen click on Stop (this ends the old configuration) and then click on Start.

Load a jOrgan organ and configure your MIDI connections. Play something and evaluate the audio. If the sound is good (with no breakup or stutters) then your JACK configuration is good. You can then tweak the Frames/Period value lower to attempt a lower latency setting.
