I would like to get an Ultrasound now that the local dealer has a bunch for

GUS. I was going to run it's line out into the line in of the PAS16 which I
would use for PCM, SB comp, SCSI and Mixer. I assume that I could set the
IRQ's at some higher number on the GUS since all my lower IRQ's are used up.
Have to keep the PAS low to use TBPro. Has anyone else done this yet?

Subject: Need to find instuments in Voyetra for the PAS-16?
Date: 23 Nov 92 17:35:53 CST
Organization: University of Kansas Academic Computing Services

Hello netters,

I have been playing with the Voyetra song editor that came with my PAS-16.
I want to create a song with it or Modedit/GTS.  Firstly, there seem to be
200 different synthesized sounds that Voyetra can produce.  Does anyone
have a list of what instruments each of these sounds are supposed to
represent?  I need a bass guitar, an acoustic guitar, and a drum (maybe 
snare) for starters.  I would like to just go down a list and pick, but
I can't find a list of instruments.

Also, I assume that using Modedit or GTS to create a mod would yield a
higher quality song.  But what do I do for instruments when creating a
mod?  Do samples come with Modedit or GTS or do I have to sample my own
instruments?  

Thanks in advance,

Yes, on a 25 Mhz i386.  I'm using the PAS16 in its default installation
mode; same with the 1542, except that I shut off its floppy ports as
I already have floppy support on another board.  I'm running 3.1, DOS
5.0, and the Win 3.1 drivers which came with my PAS16 (which means
they're probably pretty old).

One thing I *did* fight with for a while was what made my TBPro
stop working.  It turned out to be my emm386--it takes the i386 out
of real mode so it can intercept I/O's (I guess), but this seems
to break TBPro.  So now I load emm386 when I want to run Falcon,
but don't load it otherwise.  Since it also breaks GNU C for DOS,
this doesn't bother me too much.

Well, it looks like its time to upgrade the old ThunderBoard to something 
better -- I'm pretty sold on getting the GUS -- but the quesrion of the hour 
is:  Just how well does the SB TSR work?? 

Yeah, yeah, I've read all the other posts, but can someone who actually has
one PLEASE tell me if it is SB compatible.  I mean, my thunderboard may be
crap -- but it sounds awesome when I play WIng Commander, and I've never 
played a game that supported SB or Adlib that my Thunderboard didn't work
on.  

Now don't get me wrong, I know that the GUS is new and pretty soon everyone
and their mother is going to support it, but I plan to buy this card NOW, not
later -- so therefore I want it to work with the stuff I have NOW.  I 
understand that the current TSR only supports the SB -- since the current 
trend seems to be going to the SB Pro, I assume that they will come out with
a new TSR to support the Pro Right?  Or will they?

now whenever i play a sound, it comes out _incredibly_

but i do have an adlib card (i know, it's old and useless

and if i install the driver for the adlib to play wav's,
everything comes out at the right speed (except that there
is this incredible hissing and an annoying high-pitched
screech).

so, can someone tell me what is wrong with the sound src
driver, or how i can get my dac to work?  or does anyone
know how to get the hiss and the screech out of my adlib?

anyone?  anyone?

I don't think the Trident detection is working properly.  I got the same

OK, second try, since I got some information wrong in the first post.

I'm looking for a .SNG to .MID converter.  There appear to be several
different formats of the .SNG standard (the one most sequencers use) out
there, but I THINK that its just a case of the headers.

Example: I have Voyetra Sequencer Plus Pro, which saves to .SNG and .MID,
and a friend of mine has (I believe) PC Musician, which also saves to .SNG
format.  However, I cannot take his .SNG files and load them on my
sequencer, and neither can he.  HOWEVER, he owns a transcription program
which can read BOTH of our files and transcribe them flawlessly, indicating
that the way the NOTE information is stored is the same.  I'm therefore
looking for a program that IGNORES the header information and converts the
note infomation directly to MIDI.  Any Type of MIDI file is fine, I can load
all three.

Thank you.

Is there a FAQ list for sound cards somewhere? I'm looking for a capable

the Thunderboard, partly since it comes with F15 II, a decent game. I
looked at the Thunderboard for Windows package, but that looks like all you
get are a few utilities to play sounds while in Windows. Heck, I can find
good stuff like that on the net.

I agree that limiting music on the GUS to MOD format would be a waste, IF it 
were standalone music in a music player or editor. However, when writing 
games it is entirely unpractical to support the GUS using all 32 channels; 
most people are listening to the music with Soundblasters and other simple 
DAC devices, and there is just no way to play music created for 32 channels 
on 1. Don't underestimate the MOD format. In the game (Star Control II) 4 
channels of the US are for music, and four for sound effects. The results 
are fantastic.

Hi, 
you might want to try the following: With every new installation process, their
SETUP program seems to pull down the volume! So, first of all, you should check
the volume settings. Then please note, that from the release of the third beta
package on, there are no different interrupts under DOS and Windows allowed.
Also from the last beta package on, the MVPROAUD.DRV creates some settings in
your WIN.INI. These (four, I think) settings are something like the following:
WindowsUsesDosSettings=
CDPCMicOverride=
InheritDOSSettings=
(can't remember the last one)
So, go ahead and delete them from your WIN.INI as they have been moved to their
own MV.INI file, which the new MVPROAUD.DRV creates. You should check the drivers app in the control panel, with which you can control these settings. You 
have to try around a little bit, but it works fine wiht me!
BTW, Media Vision should better include some information, at least a general
README with some information would be good. They didn't even put in a README
for the new Pocket Recorder od the CD App.....(maybe they're assuming that 
everyone got the latest beta drivers)!

Hope this helped,

Tim

If all that is needed is a driver, is it possible for the companies to
release drivers for games already out there?  If its basically the same
driver they won't need to do much extra work if they plan to support GUS
for future games.  This might reduce some of the complaints about certain
games not working perfectly with the GUS's SB emulation.

Yeah, GTS does that. It is an EARLY version of the package and doesn't
print out your score and has some video bugs but so far it works fine
with my system. You select what note you want, drop it where you want

The GUS comes with pretty lousy software, actually.  Its playback
utilities are good, but the recording software is virtually useless,
and no sequencer is provided.  It's a shame that a card this good
should be bundled with software this lousy.  However, quality third

I am using sbpro 2.0 and a yamaha yfp-500.

This is probably a faq, but, please help if possible.

I have some .mid files that run just nicely on the sbpro fm.

The percussion (on channel 10 on the sbpro) sound just find.

But, when I play the songs through the keyboard, everything works okay
except the drums.  They make odd noises (like someone is playing the
notes in a different and wrong key.)

So, I can just turn the drums off and things or find.  (Or play the song
through the keyboard and the drums through the sbpro simaltaneously.
Which is something I DON'T want to do.)

So, the question is:  How can I get the drums to play correctly through
the keyboard?

I've read the complete manual on Voyetra and the Yamaha and the only
thing I can figure out is that the keyboard plays drums on channel 16
NOT channel 10.  So, I changed this... no luck.  It was still jumbled.
Both manuals claim their rhythm sections are fully 'general midi
compatible' and meet "everyone's" (i.e. Microsoft's) standards.

Obvioulsy, something is wrong.

Any ideas?

Is this a problem I would have with every keyboard, or just this yamaha?

ANY help or comments would help.
