Scott,
Was that really the case for 2.4?
I have a vague recollection of a SNDChannel external but don't recall coming
across it in HC 2.4. But I could be wrong.
Sound channels were implemented directly into the HC engine sometime
after the 2.0 release (can't remember exactly when.)
The advantage of this approach was that some very complex music could be
created on the fly, using scripting only, without the need for large
sound files. Similar to MIDI notation, long or complex music could be
generated using only a short script, and the only resource necessary was
a small sampling of an instrument sound file. The resulting music
probably wasn't good enough for commercial work (with the exception
possibly of some children's software,) but it was wonderful for dynamic
music generation.
The very best use of sound channels I ever found in HC was a rendition
of a Bach Chorale. It employed 4-part synchronized harmony, played by
the embedded "flute" sound that shipped with HyperCard, using a small
and compact little script. I'm sorry I don't know who transcribed it.
I'm also sorry that none of my emulators will play all the sound
channels any more, as it was a beautiful little thing. :(
