>(Sorry, I don't have the FAQ)

Advanced Gravis is located in Barnsby (sp?) near Vancouver, Canada. Their 
phone number is 604-431-5020. You probably won't get any boards from them, 
though, as they do not (normally) sell to end users or retailers. Try some 
mail order store, like ComputAbility or Telemart. You'd probably get a 
better deal there, too.

>2) How much memory (RAM/ROM) does the GUS have on it?  Is it possible

It has 256KB RAM (standard 44C256-10) standard, but can be expanded to 1MB.

>nice 8 MB or so digital piano?

Not with the included software. The board itself cannot address (as far as I 
know) outside the 1MB on the board, but I guess that it would be possible 
with some "dirty" programming or something.


>3) Does the GUS card have a SCSI interface on it?

The GUS supports CD-ROM controller daughterboards, currently the LMSI 
version is available. SCSI will be in the near future, so will generic NEC 
and Mitsumi.

Hello,
I forgot to tell you about my MusED, written also for PC speaker.
Yes, it's very simple editor which plays music (5-Voices). It 
doesn't use sampling method for playing, just like you're using electric
piano.

Um, could you name any?  Best I can tell, fast is 300 ms or under, with the
fastest at around 280 or so.  There are inherent delays in the technology,
having to do with the spiral track, heavier optical heads, denser data that
takes longer for the servo to track, etc.  Furthermore, in addition to the
seek times, CD-ROMs rotate at 200-500 rpm (depending on where you are in the
spiral); even a new double speed drive rotates at 400-1000 rpm.  Rotational
latency becomes quite daunting in itself at those speeds (in addition to
seek time); calculate it yourself.

>10 ms hard disks are available, typical speed is rather in the 14-20 ms
>range. So the speed factor is in the 4-5 range, not 20!

You are right there; most PC hard drives are in the 15-20 ms range; some of
the 300 MB+ ones are more like 12, and the new Maxtor 540 and 1240 are 8.5;
but these latter are very rare still.  I doubt that even 1% of existing hard
drives are 10 ms.  (Again, in addition to seek time you have to add the
rotational latency, but most hard drives run at 3600 rpm; the newMaxtors I
mention run at 6300 rpm!).

Typical CD-ROM to HD seek time ratios are more like 20:1 (300:15), the
rotational delays more like 10:1 (but more variable), and the data transfer
differences around 5:1 (also varying wildly).

Organization: Curtin University of Technology
Date: Thu, 28 Jan 1993 05:05:15 GMT

   Apologies if this is a duplicate post; our news system fell over and I'm
unsure as to whether the previous attempt went out or not.

   I have some .VOC files which used to work fine on my old Sound Blaster
(1.0, I think). I now have a nice, shiny new PAS16; it's definitely worth the
outlay, but I'm having trouble playing the old .VOC files.

   If I use PAS16's PLAYFILE, I get a loud burp and little else. If I use
VPLAY.EXE which came with the Sound Blaster, they actually try to play.
Sometimes the whole file plays correctly, and sometimes it stops after a
syllable or two. And, of course, almost anything in between. I gather that
these particular .VOC files are 'packed' (whatever that may mean; I assume
they're compressed in some way and expect either the hardware or software to
uncompress them). I want to convert them to .WAV format so I can use them
under Windows. Anyone experienced this before?

   Oh yeah. As far as I can tell, the PAS16 is working fine in all other
respects.

That depends.  Who are you buying it from.  I bought a Diamond VRAM

found out that the 5 year warrenty is not transferable.  Guess what just
happened about a month ago... It died.  I am going to have to pay $65 for

If you get a great price from a person, it may not be the best deal
overall.  Always try to buy from a vendor.

	I've been following the thread about the GUS v1.22 disks.
From what I understand, there is a file missing on the v1.22 disks
that came with the v1.21 disks.  I took a quick look and I couldn't
determine exactly which file was missing.

	I would appreciate it if somebody could post the name of the
file that is missing, and where it is.

	I'm also assuming that I can use ezarc to add the missing file
to one of the 1.22 disks.

thanks in advance

Add PAS-16 16-bit stereo support.  Why?  Because, the DAC is cleaner and
less noisy than the SB Pro's and it has 16-bit stereo support.  Sure, the
Gravis is a really nice card and it's wavetable synth blows away FM, but
there are still alot of PAS owners out there (more than GUS right now).
Also, have you heard about the Mediavision Shareware contest?  You can
win $5000, $2000, $1000, or $100.  Write something for the PAS-16 and make
some money!

... which is why the next generation of PC (and workstation) motherboards
have sound on the board.  The problem, as always, is pinning down the
quality and features needed by the lowest common denominator of MM users.
CD quality stereo recording?  Telephone quality?  Integration with any
sort of video playback standard and codec?  Speech synthesis?

I think professionals who do audio production will continue to fuel the
demand for add-on cards from companies like Turtle Beach and Roland.  I
suppose gaming and "business audio" (whatever that is) compose the lowest
common denominator whose needs will eventually be met by audio on the
motherboard.

Here's an interesting question:  what do YOU think "business audio" is?

Sorry to do this to you, Andreas, but you've really got it all wrong.
First of all, it's the NYQUIST theorem, and it states that the in order
to capture any given AUDIO frequency, you must use a SAMPLING frequency
that is twice the given audio frequency.  What (supposedly) is happening
in the SBPro is that, due to some sort of inadequacies in the circuitry,
its frequency response rolls off at 2.6 kHz.  You can sample at however
high a frequency you want, but you WON'T reach the theoretical frequency
responce of your sampling rate -- even at 44.1 kHz SAMPLING frequency,
you won't be able to produce AUDIO at more than 2.6kHz.  Needless to say,
if this is true, it's a really crippling defect in the design.

Except when actually using it. The voice recognition is a powerhog and the
sound quality of the card is pretty bad, and is not even MPC compliant,
a spec that Microsoft themselves set.

Subject: midi/sound on computer questions
Organization: Brown Computer Science Dept.
Date: Wed, 27 Jan 1993 18:31:49 GMT


okay. i want to invest in sound and midi stuff for my current or
hypothetical new computer. any advice or guidance would be
much appreciated.

first: what i want to do.
- i want to use the computer as a sequencer. control, through midi, 
  synths, drum machines, sound modules, samplers, or whatever - external
  musical equipment. so i'd need a midi interface and good software
- i'd like to be able to play sounds stored on the computer. i assume that
  there are all sorts of instrument samples, songs, etc at ftp sites and
  i'd like to be able to play them.
- i want to record my own sounds. sample interesting vocal bits, instrument
  sounds from CDs or off of a synth or drum machine. a sampler, basically.
- i want to edit the sounds after i've got them. reverse them, crop them,
  maybe stretch or compress them time-wise, whatever.
- i'd like to be able to make my own sounds, as if i had a synthesizer at
  my fingertips.
- i want to play back my own samples and anything else i have under control
  from the sequencer. i.e. be able to treat the sample playback part of
  the card(s) just like any external musical instrument and control it
  with whatever sequencing software i'm using.

second: what i want to know.
- what are my various options for getting all or most of this done?
- how much will each option cost?
- what won't i be able to do with various options? (or what won't i be 
  able to do well?)
- what will i be able to particularly well with each option?
- how modular is the setup? (i.e. could i buy a midi interface and sequencing
  software now, add sound playback ability in a little while, and eventually
  add 16-bit sampling capability)
- what hardware do i need? how much RAM? hard disk space? how fast a 
  processor?
- i am not particularly interested in compatibility with SB or whatever for
  the purpose of playing games, though i am, of course, interested in what
  might not work with what (other hardware, software)

i realize these questions are probably much-asked, so email may be the best
way to respond. also, i've seen mention of something called the sound 
newsletter. what is it and how do i get it? are there FAQs that might answer
my questions and where do i get them? are there other sources of information
i should check? are there questions you think i may want to ask that i 
haven't? have you had enough yet?

thank you very much

mike

Hi,
I am a happy owner of a PAS 16 board.
I have the Trantor SCSI driver for my CD-ROM - works fine.

What I am looking for is:
I need a SCSI-Tape driver for the PAS16-SCSI to do backups to SCSI-Tape!
The TRANTOR-SCSI dirver does recognize the SCSI-Tape !


PC-TOOLS V8.0 only supports ADAPTEC SCSI - boards ......

Any Idea ? - Is there a spec how to interface to Trantor SCSI dirver ?

Please do not forget that the Wave Blaster has a MIDI brother, the Midi
