Beta Test

Beta Test version of OrganAssist 2.8 for both MacOS and Windows 

In addition to support for MacOS version 2.8 includes the following changes:

Classic Organ Works – now supported
Peterson – now supported
Rodgers – support added for variable ID codes
Solid State – support added for newer systems
MIDI Feedback Protection – to stop “sticky notes”
Track Edit – Move notes between divisions
Track Edit – Highlight groups of notes
Library and Playlist – improved usability
Playlists – can now be set to repeat automatically and/or shuffle tracks

This new version includes major changes “under the hood” to cope with the technical requirements of running on MacOS instead of Windows.  However, the appearance and main functionality is mostly unchanged since version 2.7

If you wish to try this test version then please use one of the following download links.


You can see a series of videos about using OrganAssist on the Videos Page

*** IMPORTANT *** – Due to new security measures in MacOS Sierra, this application will NOT run if activated from the Downloads folder.  See instructions below to avoid/resolve this problem.

The application is now CodeSigned which means that MacOS will validate the application and give a warning message if it has been damaged during the download.  Downloading a second time should resolve any problems.

** If there are any fixes/updates to this version, I will post information on this page and amend the download links as required. **

Known Bugs

MIDI data loss on MacOS ONLY if large numbers of messages recieved (for example from Hauptwerk combination pistons)

MacOS Sierra – Gatekeeper Security
Before running OrganAssist for the first time it MUST be moved from the Downloads folder to another location (Desktop, Applications etc).  Also you MAY need to Control+Click to Open it the first time – depending on your security settings.

If you have already run it from the Download folder it has created an invalid folder elsewhere that prevents OrganAssist from running permanently. To solve this problem you must go to your Home/Library/Application Support folder and delete any folder(s) starting with com.organasssist (the name will include a random number). After deleting any com.organassist folders, move the application from Downloads to another location using Finder and then run it again.
