I am unable to select these same midi files for conversion in MidiSurgeon, presumably because the File Kind is "Unknown" and so they're filtered out of the file chooser dialog.
I'm unfamiliar with how Finder recognizes these file types, clearly it's not by extension (.mid).
Any hints?
Thanks!

GS/OS uses filetype/auxtype flags to associate files similar to what
classic MacOS does. I personally use the File Manager NDA to change
these, but I'm sure there are other tools.

There's a filetype byte as part of the catalog entry for each file.
MidiSurgeon may key off of that - so just getting a filetype changer to
make that change for you might do the trick. You'll need to know what
filetype it expects, first. You can do that by having MidiSurgeon save
a new file of a type it likes, then you can inspect that for its type
and make your Unknowns be of that type. [It's easiest to find a program
to do this for you; TCHANGE is one I've used in the past, which runs in
P8. I usually just bring the disk image up in CiderPress and use that
to modify the type.]
The danger, of course, is that MidiSurgeon may need something a lot
deeper than that - like a resource fork, which would be altogether
missing in your case, or some other gorp in the "MIDI" file that
MusicModifier doesn't supply. I don't know anything about MIDI, so
maybe one file is the same as the next, so you don't have to worry about
deeper incompatibilities.

Thank you both!
This was exactly what I needed to learn, and FileManager did the trick. $D7 happened to be the Midi format that MidiSurgeon was looking for, and it chewed through the conversion without a hitch.

Mike,
Here's a shot in the dark that might work for you.
Some GS/OS applications, when in the file dialog, accept an <OA-A> to
show (and allow selection of) all file types.
Whether MidiSurgeon does, I can't say.
If you haven't already tried it ...

I never knew that trick! It seems odd that it is OA-A, which normally is
'Select All', rather than OA-I.
Many times I have needed to change a filetype after transferring a file
using SAFE2. I think I need to add a new feature to SAFE2, that if you
have an entry selected in the Home folder, OA-I will bring up a box that
displays file information like the File Manager NDA does, and lets you
change the file/auxtype.
I have added that to my "To Do" list...
Cheers - Ewen

Ewen,
That may be because it is *my* memory that is at fault here.
My recollection was that the <OA-A> 'trick' was from GS.Shrinkit.
To confirm, I just launched GS.Shrinkit. I was wrong.
Instead, GS.Shrinkit, in the file dialog, has (2) radio buttons:
o Show Only Archives
o Show All Files
So, unless it was some other application that has escaped me at the moment,
I passed on an invalid 'trick'.
I certainly do like your planned OA-I to add/change File Type/Aux Type info
on the spot!
Thanks for continuing to add to your already impressive volume of work.

QLabs published 6Pack which has a PIF called MoreInfo (System/System.Setup/MoreInfo) which allows changing filetype etc. <Shift><Apple><I> as opposed to <Apple><I> in Finder.

Hugh,

I think it falls into the category, of 'Why did I not think of that
myself'. I do have the ability in Phoenix to change file/aux type, and
the access flags, but it would be more useful for every day use to be in
SAFE2.
As I said, I have added it to the "To do" list, so it will get done in
due course.

I do seem to come up with new ideas every so often, so hopefully by the
time this year's KFest comes round, in Ryan Suenega's famous words, "I
won't suck"...
