I'm sorry, I made a mistake, this would double the speed since you will end
up with less samples.

To half the speed, simply overlap your FFTs by 512.

Of course you can transpose by any factor by spacing your FFT's starting
point by x/(FFT's length) where x is your transposing factor

I think if a midi sequencer can't record midi accurately, it pretty well
has zero functionality.  If I watch the Error gadget (Huh? why would a
midi sequencer even HAVE an error gadget, you ask?) and play even simple
monophonic notes into Music-X it will tally approximately 1 note error
every 8-10 notes....those errors are 'hanging' notes - notes without a
note-off and that's wholly unacceptable.  The other area of dysfunction is
the Library section where the sysex librarian features of Music-X lie.
What can I say? .... midi errors abound here, too.  BTW, I was using an
1M Rev 5 A500, 1.3, and an ECE interface; I tried Music-X on four other
similar setups with various midi interfaces and got the same thing.
Subsequent back & forth mail with Matt Nathan at MicroIllusions finally
had David Joiner (programmer) flaming Commodore's hardware & OS rather than
his own midi driver.  Dan, if that stuff ain't happening to you, then
you've got a 'good' release.  This was version 1.1......1.0 had done the same
thing when I had hoped they'd fixed it.  Something very fishy about that
Micro'sIllusion outfit - they blew me off completely after that episode.
With the release of Music-X 2.0 I will renew my own efforts to seek justice,
but as it stands now, with their complete failure to follow up and their
cavalier blaming of others for their own technical lack I have become
dis-Micro-Illusioned.  I wouldn't have bothered if I didn't think the
program had a kernel of merit, but slowness also made it unusable - slowness
in screen updating and in the roundabout notion of explicitly 'storing'
and slotting sequences for use.  I liked the grid, though, too....maybe too
much - before long, I found myself accomodating the graphic aesthetic of
grid display rather than the music and that's when I went back to KCS.  It
was like the difference between television and radio - with radio, the images
were in my head, not on a screen...but, hey, that's just me and MY foibles.

Well, maybe you should give Sunrize a call about the next card ?  They might
even give you a Betatest-version... :)

Seriously, since this card and probably future cards from Sunrize is 8 tracks,
the Messy-DOS solution with only 4 tracks doesn't sound that attracting anymore...

This method isn't very accurate, and I'll give an example:

Suppose our signal has two peaks, one at 1Khz, and the other at 2KHz.

1. we upsample by 100%, we now get the two peaks at 500Hz and 1Khz.
2. by multiplying with a 500Hz sine wave, we get 1Khz, and 1.5KHz peaks.
   if we use 1Khz, we get 1.5KHz and 2KHz peaks.

This demontrates that the method above doesn't exacly preserve the spectral
content of the signal while making it longer.
However, I think that for small speed variations it should be bearable.

Not a valid complaint; a preference of short mods is, how shall we say...

I did warn people that it was techno... and most instantly realize what

tends to be the opposite of music.  However, I was aware that many people

Hmm... to me, most of the mods I end up grabbing are trash incarnate (whether

usually better to rip from demos/games.

Well, goodbye, NetLand!  I hope to get back on ASAP, but don't know if I'll

Organization: RL
Distribution: usa
Date: Wed, 26 Aug 92 13:05:04 GMT


First off, before I begin, I take no responsibility for the work in the archive.
I only redrew the schematic (which was wrong) and modified the parts list
to correct it. Mine works, built exactly the way the diagram shows it. 

I'd also like to thank Fred Hamilton from National Semiconductor for the
help he gave me when I was debugging mine. You saved me a lot of time and
frustration Fred!!!

Now then:

I'd like to announce a the upload of a do-it-yourself audio digitizer to
the incoming/hardware directory on wuarchive. This digitizer is based around
the ADC0804 A/D convertor chip, and is capable of good quality mono sampling.
Stereo can be achived by using special software (such as Perfect Sound) by
digitizing the left and then the right channels and appending them together.

All the parts for the digitizer can be bought for under $20 and the unit
can be made extremely small. I've tested it with MED 3.21, Protracker, Animan,
VCLI4, and AGMSRecordSound/PlaySound without any problems whatsoever.

I encourage everyone to try this hack. It's pretty easy to do (now with the
right schematic and parts!!) and a real bargain.

If you have any problems with getting it to work, or understanding the schematic,
I can be reached at the folowing E-Mai addresses:

kopackm@lonex.rl.af.mil     (in the summer time)
kopack@bugs.rl.af.mil          "     "     "

There could be two Mobys. There's the first who's a rather famous
American and has a hit here in the UK last year with 'Go' and has
recently done some remixes of the Brian Eno single, and then this bloke
who writes the mods who's French; his address is in the mod files.

Of course the US moby could use an amiga, but he didn't have one when he
was on top of the pops!

  I don't really know where the hell you get off bashing like this.  Just
  for your information, $20 of mine has been set up in the U.S. chapter
  of the "U4ia RELEIF FUND"  For those of you wondering what this is, it is
  a site in the United States where U4ia music lovers can send a simple
  dollar in an envelope to:

                    U4ia Releif Fund
                    1303 N.  400 E.  #5A
                    Logan, UT 
                    84321
  
  And the end of the campaign, all $1 will be taken and checked into an
  international money order payable to him.  I have worked very closely
  with U4ia to set this up.  We figured that if more people send smaller
  amounts of money, it would be easier.  It is kinda hard to send $1 over
  seas.  It costs more than that just to get the International MO. 

  As for getting U4ia mods?  Everybody knows that they are FTP-albe

For those who wonder how to transpose a signal, here's how it is usually
done:

First you must compute the Fourier transform of successive sample segments so you get a time varying spectrum.

Then you must compute the inverse Fourier transform and concatenate your
waves.

For example, if you want to half the speed of a signal while keeping it's
pitch, compute several 1024pts FFTs spaced by 1024 pts (i.e. starting at each
2048*n sample) and concatenate the result of the 1024pts IFTs.
