Is MSP compatible with the Sonic Solution audio cards ?

Subject: MSP sound input quality on PTP225

Has anyone had difficulties with the sound input quality on the Power Tower
Pro 225? When I listen to the "through" sound in the monitors and sound
control panel it sounds great, when I try to bring it into MSP or use other
sound apps to record the signal (sound hack, SE16, etc), the result is
distorted.  It almost sounds like I am only getting 8 bit samples no matter
what I specify.  I've done all I can do to explore hardware or software
conflicts.  Any ideas?

thanks!

Jeffrey,

Thank you for your response.  So are you able with the above mentioned video
projector to zoom in on a portion of a Powerbook screen, say a 320x240
movie?
How is this done, through settings on the video projector itself?  Did
having
a video projector connected to the computer slow things down even more?
Basically I want my Powerbook to be running the smallest size movie and
having
only that movie captured and blown up by a video projector for presentation.

Thanks!

Subject: MSP wish list

What are the chances of seeing any of the following in future versions of
or supplements to MSP?

(1) Precise filter specifications.  For example, for lores~, what's the
exact mapping between
  {cutoff freq, resonance factor, sampling rate}
and
  {coefficients in y_n = a_0 * x_n + b_1 * y_{n-1} + b_2 * y_{n-2} }
?

(2) More code examples.  Particularly helpful would be examples which show
how to access buffer~ objects (e.g. the source of the index~ object, or
something similar).  The source for tapin~/tapout~ or comb~ would also be
helpful.  (I'm assuming that making to source code of a few objects
available won't compromise any MSP trade secrets.)

(3) MSP status window from menu.  It would be nice if one could open the
MSP status window via a menu item.  Also nice would be if the MSP status
window remembered its position (across quit/launch).

(4) Virtual time when writing to file.  The basic idea is to have the
option of directing output to a file in virtual time rather than to dac~ in
real time.  The way if you had a patch which was too demanding for your
cpu, you could write  the output to a file and listen to it later.  If it's
too difficult to make Max's millisecond timer synchronize with the DSP
process running in this proposed "go as slow as you need to" mode, it
shouldn't be too hard to write an alternative metro object which uses
samples rather than milliseconds as it's timing base.  I'm thinking of
something like this:

  loop {
    compute a vector's worth of samples;
    write the samples to the file (or the file's write buffer);
    advance the virtual millisecond timer by (vector_size/sr) seconds;
      (or maybe the regular timing objects are disabled)
    handle any regular Max events until the queue is empty;
      (if the number of events processed is greater than a (user
specifiable)
      threshhold, assume there's an infinite loop and abort)
    ignore any user interface objects (perhaps they're disabled anyway);
    report number of elapsed virtual seconds in the Max window periodically;
    stop if elapsed virtual seconds is >= stop_time;
    stop if Max has received special stop message;
  }

Is this doable?

I just use the serial object in MAX and the same in Director.  You can
specify the port, so if you have enough CPU grunt you can run MAX out the
printer port and feed Director in the Modem port on the same machine.  I
have implemented several control approaches this way using Lingo in
Director to recieve a defined string from MAX (ie. AA01 etc)

Cheers,

Garth
