Hi all,
Been a while since I last posted just to say "hi", but now I'm back in PARIS world again,
bouncing things from analog to digital and back again. It's a great way to work, but I'm having a
real problem with pops. These pops are unusual in that, if one opens a project file, they appear at
certain times during playback; however closing and re-opening the *same* project produces these
little pops in different places during playback. When keeping the same project open and playing
through the song multiple times, they seem to remain stable.They're also unusual in that they're
very small and hard to find within the waveform, but once you find them, you can open up a
millisecond of empty space (with perhaps a millisecond of crossfade before and after) and they're
effectively eliminated, usually but not always without audible effect.
I use an external clock, so of course I've tried PARIS' internal clock both during playback,
but this didn't seem to help. I've tried re-transferring the files from analog 16-track several
times, but it doesn't seem to be an A/D converter issue, since this didn't help. I've tried using
different hard drives to stream the files, to no avail. I've tried using a different MEC for output
to my console (I'm mixing out of the box) with no improvement (the other MEC also provided a chance
to use another MEC-to-EDS cable to rule that out). I've tried removing the 8-in cards and cleaning
their contacts with De-Oxit, as well as cleaning the MEC-to-EDS connector cable. I've tried using a
different EDS card (I have two functioning cards, one not working, but have only one card at a time
installed right now). I've tried cleaning the contacts on each EDS card. I've tried using different
slots for the EDS card.
On the software side I've tried making sure the Default project clock settings agree with the
project I'm opening. I've tried 256fs, 44.1 and Internal, each time setting the Default Project to
agree with the project I'm opening. I do this by changing the clock setting on the Default Project,
saving it, closing PARIS, re-opening PARIS (with the exteral clock set correctly, of course), then
from within PARIS opening the project I'm working on.
Since I'm only using one MEC, I've also tried including and removing "UseHouseSync=1" nad
"MidiPlayDisabled=1".
I should mention that, during the transfers, I'm syncing PARIS to MTC and the external clock
at the same time, both of which are generated by an Aardvark TimeSync II which is built for this.
(The Aardvark reads SMTPE and spits out a low-jitter clock and MTC. I believe it's electronically
identical to the half-rack version of a Rosendahl Nanosync.) To check whether it might be the
Aardvark, I tried using the OpCode Studio64 XTC to read SMPTE and generate MTC/ clock, but on
playback there were still pops. I've also tried disabling all SkunkWorks plugins by removing them
from the Ensoniq "Plugins" folder.
Oh, and I've re-installed PARIS as well, and tried using different Default Projects in case
it might be a corrupt Default Project file (but so far I've only tried using a couple different
backups of *my* Default Project-- I haven't yet tried starting with a clean Default Project). I'm
also not quite sure whether I've tried simply transferring audio without being slaved to SMTPE/MTC,
but I don't think I've tried that yet. (There were lots of things to try, obviously!) I've tried
opening different Project files, too (that is, the Project file I'm working on, not the Default
Project).
I'm starting to think that it's something in my computer (a Mac G4 Quicksilver 2002 with a
1.467GHz GigaDesigns G4 upgrade card, 1.5GB RAM), since *either* of my EDS cards, in any slot, using
any MEC, using any clocking scheme during transfer or playback, using any hard drive for transfer or
streaming, etc., etc., seems to produce the same result: intermittent, small pops, visible in the
waveform, which stay consistent when the project is left open but change completely after closing
and re-opening the project. The pops seem to move around at random, and don't stay in a given area.
I'm out of steam. Can anyone (DJ, I'm looking in your direction) *possibly* come up with a
few more possibilities as to what might be wrong?
Thanks ever so much in advance!

wierdo problems like that I've usually seen linked to heat/power supply
issues..

I thought that too, but then I read the part about the pops
showing up in the waveforms, but then moving, and then I didn't
know what to think.
What could make that happen?

Hey Brian,
Got a spdif cable plugged into something that's not turned on?
That'll do it.

Brian, I had the exact same problem a few years back, turns out it was RAM,
swapped it and pops were gone.
I am on a PC thow.
Good luck.

It seemed to me that I remembered someone having similar problems a while
back, and finally realizing that their power supply was bad. Seeing as how
the *exact* same problems seem to surface when using either one of my EDS
cards, I think this may point to powe supply issues.
Thanks for the reply, Aaron... much appreciated.

You know, one of the things I tried was disconnecting my S/PDIF cable's loop
from input to output on MEC A's S/PDIF connectors. This is set up, as you
might imagine, to do the "Brian Tankersley Digital Bounce" technique. Unfortunately,
this didn't seem to help. After doing this I noticed that clearing MEC module
cards in the MEC module window (not just clearing connections in the patchbay)
made them re-initialize themselves, or at least so it appeared (the lights
on the 8-in cards flashed). I then got the idea to try clearing the connection
from S/PDIF in to out in the patchbay as well, also to no avail.
I may not have tried disconnecting my ADAT cable, but I think I did. I
tried to write down *everything* I'd done so far, but I should've bee ntaking
notes at the time (of course I kept thinking the solution was just around
the corner, so I had to do "pos-operative" notes from, uh, memory and stuff).

I thought that too, but then I read the part about the pops
showing up in the waveforms, but then moving, and then I didn't
know what to think.
What could make that happen?

Wow! No shi-- I mean, really?
I just might be able to find a friend with some PC133 SDRAM modules to
try this out.
Of course the "TechTool" application that's supposed to test ffor bad RAM
says it's fine. Well, who knows?
I've already tried cleaning the RAM sockets with DeOxit. I'll try once
more, then it's on to new RAM.
Thanks, everybody, for your replies...
