HBPM/Macintosh Source Distribution, Release 0.01 Alpha

Here are the sources for three programs.

        Homebrew OMS Driver

        Homebrew ScalePlayer

        Homebrew Thru Application

They're described in the README file for the binary distribution.

You'll also need the OMS Software Developers' Kit (SDK) to build this. You can download the SDK from http://www.opcode.com/.  I used the 09/11/95 release.  Also, the SDK includes the OMS Specification, which may be useful.

I used Metrowerks Codewarrior release 8.0 to build these programs. You should be able to reconstruct them using earlier Codewarrior releases.  You can't compile the OMS Driver using Symantec C++. Symantec does not support virtual functions in code resources.  I don't know how well MPW would work.

In audio.c, you may run into problems with SndSoundManagerVersion(). Some versions of Apple's headers declare that routine as returning a long; others say it returns a NumVersion structure.  There's an #ifdef in audio.c to use the other form as necessary.

In the OMS Driver directory, the source files that are Mac specific are Codewarrior IDE text files (creator code 'CWIE'), and the sources that are common with the Silicon Graphics synth are BBEdit documents (creator code 'R*ch').  That's Just to make it perfectly clear which files are supposed to be part of the portable synthcore and synthcore interface.  I did have to add some "#ifdef __MWERKS__" in MIDIConvert.C.

If you use an earlier Codewarrior release, you'll have to construct project files by hand.  I've put a project dump file in each directory -- its name ends in ".TEXT".  Look at those, and also look at these (probably incomplete) notes.
