Judy,
I appreciate any and all support for my pleas to improve
Rev/Metacard's audio capabilities. I haven't yet found a satisfactory
solution to what seems like a very simple, and for me, a very crucial
procedure.However, there have been some promising, albeit
complicated, suggestions for solving this issue with built-in
procedures. I will keep everyone posted, but I may not be able to
continue testing until next week.
Just in case you, or anyone else out there, is desperate enough to
try to use any old HyperCard or SuperCard audio externals in
Revolution let me mention some that I've tried in Revolution,
without success, so far. Mostly, the converted stacks just crash,
whether from script errors or from the external itself. If I don't
find better solutions, I'll continue trying to make some of these
externals work in Revolution. I'll need to eliminate script errors to
really test the Externals.
MusicBox v3.0 by Alex Metcalf might come closest to what you mention
in that it can play "MOD" music files, which have to be created by
other applications. It extends sound play in other ways, but does not
duplicate the HyprCard commands for playing a sequence of notes.
Rinaldi's PlayIt XCMD doesn't really seem to add much functionality.
Iverson Software's SoundMaster (1.0) looks very powerful, but is
fairly complicated. Again, it doesn't play notes like HyperCard. (But
of course there would be no reason for a HyperCard external command
to duplicate its built-in commands.)
Finally, Sound Utilities for HyperCard (including Sound Playback demo
and Sound Recording demo stacks) by Lawrence D'Oliveiro, New
Zealand, are very powerful, but quite complicated to use. These
externals can allocate and play many different sound channels at the
same time, as well as access and manipulate the data in these
buffers. It seems to access many of the different system functions
for sound incorporated into the Mac OS.
Scott Rossi <[EMAIL PROTECTED]>, in improve-revolution digest,
Vol 1 #49, mentioned SndChannel, a HyperCard/SuperCard that would
"load and control as many sound resources as memory permits." This
external sounds like it might help solve my problem, but I haven't
managed to find a copy.
All of these stacks are several years old, but do at least partly
still work in OS 9 with HyperCard and/or SuperCard. However, I
haven't gotten any to work yet with MetaCard.
If anyone has successfully used similar externals in
Revolution/MetaCard, I would really like to hear about it. (BTW, I
have successfully used a set of Externals in Revolution under Windows
98, called MCPsych, which allows extensive control of sound playback,
as well as many other features. But I'm still interested in figuring
out Mac OS and cross-platform solutions.)
