Import / Convert MIDI Files

Version 3.0 has powerful tools to help import existing MIDI files from other sources.Editing

For each file you can select which MIDI channel is routed to which keyboard.  The Import Settings screen gives information about the contents of the file to help you choose.

OrganAssist contains additional logic so you can import MuseScore files in the same way, choosing the destination keyboard for each stave.

You can also use OrganAssist to automatically split long MIDI files into individual pieces and then immediately create new MIDI files for each piece.  Refer to the User Manual for details.


OrganAssist will automatically play back any recording on any other supported organ.  TranslateNo knowledge of MIDI is required.

You can import existing MIDI recordings for editing and playback on different instruments.

OrganAssist has been designed from the ground up to allow full portability of recorded music across all instruments. To achieve this OrganAssist contains a “Virtual Organ” that is capable of generating MIDI data in real time. To translate stop changes, OrganAssist contains a “Virtual Organist” which attempts to re-create the original performance using the stops available on the current organ.
