Mixing Sessions on a D8B from a HDR24/96

[Malfeitor]

Just tried a solo OPT-8 in every correlated slot 1-8, 9-16, 17-24 in both machines. Nadda. Pulled all lightpipe cables and getting the red on all 6 outputs. Installed lightpipe cables on all outputs and getting the red on all ends. Bright and perty.

Flipped it again, pulled, treated and reseated both DSP and brainboard EPROMs. Nadda.

- Both systems recognize any and all card configurations correctly on boot up regardless of position or machine.

This might be somewhat telling... I boot the console first since it's clock master and after it loads the DSP plugins for the MFX, I hit the switch on the HDR to boot. While it's booting, I see millisecond meter bridge activity on random channels and mains with corresponding pops/clicks through a beater pair of headphones on the HP1 jack (not jacking monitors into this console just yet). Assuming it could only get this through lightpipe or MIDI bus since they are the only connections.

- All MMC functions perfect. REC ARM/RDY responds on HDR, control surface functions etc.
- No anomalous behavior whatsoever. Faders, jumpy VPots, dead LED indicators.
- All faders on TAPE IN 25-48 set to unity and selected 24-48

Not giving up. Meter and oscilloscope are coming out next. Hold my beer.

Thanks for reply. Peace

It's something with the HDR. Looking into it. Once I got it up and running 6 months ago, I transferred all the session tracks from it. Worked fine. Today for debugging, I hooked it to my DAW AI to debug and nothing.

I've had a very similar experience to you with my desk and HDR with the 43 comm error after my gear being in storage for a few years, after changing the internal battery and reseating all the cards and cleaning up then resetting the bios it finaly came to life, but most times when switching on it can't make its mind up whether to sync itself to midi/wordclock or not. one time it will next time it won't.
I discovered an older thread here viewtopic.php?f=2&t=1278
that perfectly described my identical issues, it's three pages long but well worth reading, the only thing that did work in getting it to sync more often was pulling out my OPT8 card from the card cage in the 17 to 24 position before switching on, but even that didnt solve it every time, even swopping the master clock from the D8B to HDR seemed to work for a while but then failed to sync on a subesquent switch on.
It seems to be an unsolvable quirk that haunts this configuration, personally I feel its the midi rather than the wordclock thats the issue but if I'm honest I'm just guessing from my own experiences like every other user.

This might be somewhat telling... I boot the console first since it's clock master and after it loads the DSP plugins for the MFX, I hit the switch on the HDR to boot. While it's booting, I see millisecond meter bridge activity on random channels and mains with corresponding pops/clicks through a beater pair of headphones on the HP1 jack (not jacking monitors into this console just yet). Assuming it could only get this through lightpipe or MIDI bus since they are the only connections.

I have this happen when the D8B and HDR will not sync and I press the "All Input" button on the HDR, the meter bridge goes haywire on nearly all the channels and I can hear random pops and distorted clicks when monitoring through speakers and headphones but it never happens when the sync is successful.

Ok so I figured it out and it was as originally posted, my issue. I took the HDR over to my DAW console and lined it in via lightpipe like I did 6 months ago to get the priority sessions off these older drives. I have since learned the Mackie audio format schema and also backed up the HDD data just by straight IDE copy. After hooking to my DAW AI, all worked as intended and the HDR even synced WC to my AI via ADAT. Recorded a song from my PC to the HDR in two channel and played it back no sweat. Saved it and then rehooked to the console. Worked like a charm. Opened the old sessions and realized I had last saved the sessions after outputting them and realized that all 24 channels on the sessions were muted. What threw me a curve ball was that muting on the console TAPE IN 25-48 does not mute the HDR channels 1-24. Yeah, I'm getting old, very busy and can't remember everything. After all the surgery on the D8B host PSU and MAJOR surgery on the HDR. Both running latest OS and brain firmware and booting from CF. They work great and sound pretty good. At least my dumbassery forced me to go through and tend to the potential age issues in this equipment.

For historical purposes and future readers, the GIGABYTE GA-6BA works perfect in the HDR platform. Imagine it would well in the D8B host as well. It is a 440BX Slot 1 chipset config so you'll have to get a PII processor as well. Found on new on the auction site in Poland and, no joke, I got it in Arkansas from Poland in 3 days.

Thanks to all who helped me on this forum, Peter for maintaining the site, Mike Rivers and all who contribute to the database info. It's an awesome site with awesome folks.

Cheers and be well. Peace.

I knew it had to be something silly. I can't believe I didn't think to ask about the HDR side mutes. That one is easy to overlook.
