Dear Jeff,

Sorry, I don't think there's any way to make a video projector zoom in on
the image, except just carrying it so far away from the screen that you get
a quarter of the desktop filling the entire screen area (at a loss of 3/4
the projector's brightness - hardly to be recommended). If you want to
stick to the Powerbook, why don't you just blow up the movie to 640x480 and
do some heavy experimenting with various codecs. If you do enough codec
compression and defragment the movie file, you may get an acceptable
playing rate.
The video projector worked no slower than a desktop monitor connected to
the same output.

Hey Gregg,

This is a great suggestion!  I don't know why I didn't think of it.

Thank you very much!!!

Subject: Upgrade downloading problems

I've been trying to download the 3.5.8 and 3.5.9 updates from Opcode's
site, but the site is terribly slow. Any suggestions for what time of the
day would be best for downloading (from Europe), or if the update is
availble from other sites?

Subject: Re: MSP sound input quality on PTP225

I was very hopeful about this idea but it seems my problem goes deeper.  I
think I will look for a hardware solution.

Subject: lores~

As requested, here is some information about the MSP object lores~,
a second-order recursive low-pass filter.

There are two inputs--cutoff frequency (cf) and "resonance" (r),
which is an arbitrary factor that goes from 0 to 1. There is an
attempt to increase the useful range of r; normally in this design,
you don't get anything too different between 0 and .9.

rt = exp(r * 0.125) * .882497;  // weird arbitrary scaling
fq = cos((2 * pi * cf)/sr);
a1 = -2 * rt * fq;
a2 = rt * rt;
scale = 1 + a1 + a2;

(sr is the current sampling rate, i.e., 44100.0)

The filter equation is then:

y = scale * x - a1 * y[-1] - a2 * y[-2];

I made some editors for the Roland JD990 sometime ago.  You can download at:
It's not a librarian, just an editor.  The basic idea is a grouping of
parameters under a single lever.  The basic trick is a different scaling of
the lever's output to each parameter.  I have also done a couple things for
my TX81Z that allow me to edit the sound on the fly.   I got some great
results by sending a sysex message with each note on that would change one
of the operator's waveforms.  Very basic, but it keeps the sound fresh
(shall I be hip-hop and say "keepin' it real?").  I haven't really got into
librarian features becuase once I started projects like these, I found a
new infinity of sounds, meaning that I don't need to worry about the
permanence of sounds, because I can always come up with something good.
OK, maybe I'm still hung up on the analog synth world where you CAN'T save
sound, no matter how ornate your diagrams!

Why do you need to bring the poor Australians into this?  What did they
ever do to you?
