MIDI Synth

The ``S'' in ``Apple IIGS'' stands for sound, powered by the built-in Ensoniq synthesizer chip (pretty advanced stuff for a personal computer in 1986). The early versions of the operating system had tools to access the built-in oscillators, but it wasn't until System Software 6.0 was released that Apple put in place its own integrated music and sound system, known as MIDI Synth.

The music sequence file format is similar to, but just a little different from, standard MIDI file format. In addition to the notes, MIDI Synth defined its own file formats for holding waveform information and instrument specification. Playing a single song requires three files:

  • The sequence file, which contains the notes to be played.
  • The instrument file, which defines how up to 16 instruments sound.
  • The wave file, which hold 64K bytes of waveform information.
The sequence file specifies an instrument file, and the instrument file specifies a wave file. A single instrument file can be shared among many different sequences. Wave files and instrument files are usually closely coupled.

Apple included synthLAB, a program to play sequences and record MIDI input (if the user had a MIDI interface attached to the computer).

From this page, you can download ``Shrinkit'' archives of some software I've written and songs I've translated into MIDI Synth format.

Note: If you are using Netscape Navigator, you will probably need to ``shift-click'' on the links in order to get them to download to your system rather than display as garbled text.


The Software Archives

Note: You can list the software archive (.SHK) and description (.txt) files in directory format.

waveLAB 1.0
This May 1994 update to the program first released a year earlier requires System Software 6.0.1. waveLAB is an extension to Apple's synthLAB program. Its focus is the creation of waveforms and instruments for use with MIDI Synth. You can put together waveforms from other sources, or create your own waves by specifying multiples of harmonics. You can tweak all the parameters associated with instruments. Let me know if you have ideas for version 1.1.

synthfile 1.5
This January 1994 version of synthfile runs under either the GNO or ORCA shell. (It will not run directly from the Finder.) The program prints the contents of sequence, instrument, and wave MIDI Synth files, decoding them into text. When you specify the -p option, it will play sequence files. It's real handy to put it into play-only mode (no text output), give it a series of songs, stick it in the background (under GNO), so you'll have a musical backdrop while you do your other work. Archive includes source code.

MIDI Surgeon and midi2gs
When I looked into how similar MIDI data files were to MIDI Synth sequence files, I knew it would be reasonably straightforward to make the translation. A little poking around on the net turned up some source code routines to read MIDI data files, and it only took a little tweaking to get them working under ORCA/C. I created additional routines to write the information in MIDI Synth format and put the whole thing together into a little shell program named midi2gs. I added a desktop interface and the ability to manipulate and play MIDI Synth sequence files, named the new program MIDI Surgeon, and sold it for publication in the Vol. 5 No. 3 (Jan/Feb 1994) issue of GS+. An enhanced and speedier version (2.0) appeared in the Jul/Aug 1995 (Vol. 6 No. 6) issue. Unfortunately, GS+ ceased publication several years ago and EGO Systems (its parent company) no longer offers back copies of the magazine or its disks for sale. If I find out whether the person who purchased the rights to the programs wants to distribute them, I will place the information here.

MIDI Instrument Banks
Apple included five different instrument bank files (together with the companion wave files) on the System Software 6.0 and 6.0.1 synthLAB disk: Combo.bnk, Demo.bnk, Orch.bnk, Piano.bnk, and Synth.bnk. I've seen others and created one myself. You'll want access to all of them so you can choose just the right instrument when you do your own translations.

  • MIDI.bnk: I created this one to work with MIDI Surgeon. It combines several instruments from Apple's banks with ones I created with waveLAB.

  • Update to Piano.bnk: While translating several piano pieces, I noticed that some of the notes sounded awfully sour. Tweaking the piano definition with WaveLAB fixed the problem.


The Music Archives

When I was testing MIDI Surgeon, I gathered dozens of MIDI files from all over the net to see how well they converted. When GS+ released the program, I put them on GEnie, comp.binaries.apple2, and FTP sites in order to help promote it. I did the same thing when the second version was released. It's an awful lot of songs when they're brought together in one place!

Some of the translations done with version 1.0 would sound better if they had been done with version 2.0, because it added surgery commands to improve the volume level. If you find one that sounds a little ``off,'' let me know and I'll try to improve on it.

Note: You can list the songs archive (.SHK) and description (.txt) files in directory format.

``Awesome'' collection
I found several songs of interest in a collection named "Awesome." The original archive contains 28 MIDI files; some translated well to the GS and others didn't. I split the ones that translated into two groups in order to have more easily managed archives:

Awesome2Seq.SHK has some nice sounds as well, but someone else may want to try and re-instrument them: ``We Built This City'' by Starship, ``Easy Lover'' by Phil Collins & Philip Bailey, ``Every Little Step'' by Bobby Brown, ``Have You Never Been Mellow, ``Smooth Talker'' by Sade, ``Staying Alive'' by Bee Gees, plus two more unidentified songs (``walk'' and ``who'')
