Recently, I wrote an online converter to convert Notator files to midifiles.

It's free to use for everybody, as I wrote it mainly for myself and now it's still there.

You can either convert a whole Notator song (taking arrange mode/patterns into account, so get a midifile containing the whole song), or just convert a single pattern. Both output a midifile (type 1), with lots of tracks.

If you had the export module or the unitor smpte module, you could have up to 6 midi output ports each with 16 midi channels (total 96 midi channels).
As midifile only supported 16 midi channels, the converter at least ensures that midi channels of differente output ports use different tracks in the midi file.

I can import the files into Cubase Pro (on PC/Windows 11) without any problem, although some details (delay, transpose, etc, as well as system exclusive events) are not be taken into account.

If you want more technical data of the notator song construction and the working of the converter tool (all nicely put together in an eleven pages PDF document), you can drop me an email via the contact form of the same site (where you can find the online converter).

The link for the converter tool is:

Hope this is useful for someone here!
