OrganAssist is maintained in my spare time. I will try to resolve any problems and am happy to attempt developing OrganAssist to support new manufacturers if necessary. Please use the Contact Page to give feedback or ask any questions.
Known Bugs in current version (3.0.1)
The Polyphony value displayed during General MIDI import is inaccurate.
When choosing a coupler from the Equivalent List, the Division options should be hidden immediately.
Please contact me if you identify any other problems.
Windows Installer – XP to 10
Note – OrganAssist is NOT supported for use on systems with the G.O. software installed. The effects reported include random freezes and crashes even if G.O. is not running. Uninstalling G.O. and then re-installing OrganAssist may possibly resolve the issue in some cases.
Existing Users – please back up your Documents/OrganAssist folder prior to installing.

Windows SmartScreen Warning As an independent developer I do not have the resources to certificate the program installer and so users of recent versions of Windows may get a warning message “Windows protected your PC”. If you click on More Info and the Run Anyway, OrganAssist should install correctly.
macOS – El Capitan to Mojave only
Due the statement by Apple, in September 2018, that 32 bit apps will not be supported in future, I do not expect OrganAssist to work on the next version of macOS. It is not possible to convert OrganAssist to 64 bit. However, OrganAssist should continue to install and run on systems using macOS El Capitan through Mojave.
*** IMPORTANT *** – To run OrganAssist on macOS you will need to download both OrganAssist and also the OA Midi Helper application. This is required to prevent MIDI data loss on input to OrganAssist. Please see the User Manual for instructions on configuring your macOS setup.
Due to security measures in macOS , this application may NOT run if activated from the Downloads folder. Move the application to your desktop or other location and use control + click to open it the first time.
Both applications are 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.

macOS – Gatekeeper Security
If you have already run OrganAssist from the Download folder then this 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.
