Hi,
Has anyone actually got any GUS stuff which utilises the 3D sound capabilities
of the card. If anyone knows where I can get a decent sample-tracker
supporting the 3D sound widget in the GUS then LET ME KNOW QUICK!!!!!!!!!!
I am particularly interested if anyone here knows of/written a sample-tracker
which makes the GUS produce Dolby Pro-Logic Surround Sound signals. I
have found out that this requires some tricky programming e.g. 'reversing
the polarity of the audio signals in order to position the sound behind
the listner'. If anyone know ANYTHING about this, PLEASE HELP!!! I
desperately need such a utility for some Soundtrack production.

Here is a tiny midi file which illustrates the above. First, it has several
patch changes coincident with note-on events. This works fine (with
WinCake2 and Winjammer Pro) - then Phat's example follows (with flute
substituted for bright piano). On the GUS, the organ is never sounded,
whereas on both the Roland SC155 and the Korg 05R/W, both notes sound
correctly. (I have access to a Yamaha TG100 as well if anyone needs to
know that).
I think that the GUS is unable to play more than one instrument on a given
track at one time - or at least the drivers make it that way (I'm using
the new drivers).

Subject: Space Debris MOD file
Well, I'm stumped! The Space Debris MOD file that comes with the GUS disks
(both the 2.06a and the old 1.21 that I have) used to work well with some
players (ZZPlay, Metal, Mod4Win, GusMod, etc.) and some not so well (I can't
think of any off hand, although some versions of DMP). I love this MOD.
Anyway, I was testing out some new players and noticed that Space Debris was
missing a sample during playback. I can't remember the exact name of the sample
but it's number 16 according to ZZplay, and first occurs during pattern 14.
Anyway, after tossing a bunch of new players, amazed by the amount of
coincidentally similar bugs in each, I decided to try it in ZZplay. It didn't
work either. In fact, I can't find a single player that'll play it properly
anymore. Fortunately, I had backed it up from a long time ago, so I restored
it and compared the two, they were identical in date, size and byte for byte
according to DOS's FC. So it came as little surprise that this copy too
would not play correctly.
I changed everything I could think of except base port of 220, the default.
I loaded my system clean, with just DOS 6.2 and doublespace (this is a recent
upgrade, could this be it?), no memory manage, disk cache or anything. ZZplay
and GusTracker both report this sample to be 164 bytes, which is much lower
than the other samples. There is a faint noise played where I should be
hearing a nice fatty synth, so I guess it's laying what it thinks is the whole
sample. I also noticed this when I installed a friend's GUS on his machine
and I figured it was something weird with his hardware (SCSI, AMD 486-40,
1.7G hard drive, Herc et4000/w32i, and lots of hassles -- paying the price
for being on the bleeding edge). My stuff's quite standard (386dx25, C&T
chipset, ATI VGAWonder, IDE controller) and I never had a problem with
anything else GUS-wise.
Sorry, for being so long-winded. If anyone has a similar experience or can
refute my claims -- or better yet, has a solution, I'd be very grateful.
Thanks
Carl
