Description
Using LSL5 for Macintosh Floppy ENG, game is recognized. However, when MT-32 emulator is selected launching game pops up the console with ERROR: Failed to find MIDI command byte!
Switching audio to adlib emulator, game launches. tested on Mac with ScummVM 1.7.0, and on the daily build 1.8.0git694-g63f2ba2 sep 3 2014. (on the daily build, resource forks were missing since they don't transfer easily to Windows)
since running the Install is a great challenge, the contents of each floppy were dragged into one folder. On the Mac, resource forks seem to have been preserved on the .drv files. (confirmed with ls -ls and derez)
Have I missed something?

What's the size of the file?
1.PAT is 16907 bytes. MD5 (1.PAT) = c3318de0cd50b371c78cd115ca92a994
I'm just using the MT-32 Emulator in this case. I do have an MT-32, but it has never been set up on the Mac.

kq5g5: I think it would probably be best if you could attach a text file to this bug containing a file listing of your LSL5 Mac datafiles, preferably with full file md5sums?
The OSX command line "md5sum" tool will give these.

@digitall No, that will be completely unhelpful.
I spoke with Walter about this one. The problem is a extra byte at the end of the file that throws off our detection of patch type.

"completely unhelpful"?!
Since the user seems unclear where he has copied the files correctly, it would seem useful to ensure that they are identical to a developer who owns LSL5 Mac... but I am obviously wrong.
I could not see how you had reached the conclusion that this was due to 1.PAT when "I don't have LSL5 Mac (nor an MT-32)".
I assume you checked with waltervn, who does own LSL5 Mac and a MT-32, he tested this and it also failed for him and this is the reason?

OK. That is clear now.
I would offer to help test as I have a MT-32, but as far as I can determine all of my SCI games are MS-DOS/Windows versions. Sorry about that.

Using the advanced OSX 'head' command, I gave 1.PAT an 8-bit derriere-ectomy, and tried again.
It worked!

Thanks for your bug report, that was indeed an extra junk/unhandled byte in the MT-32 patch file.
Fixed in commit ae2be20a20, after speaking with waltervn. Closing as resolved.
