Pyramix LTC out problem?

Postby lgabiot » Fri Mar 09, 2007 07:17

Hello,

While trying to slave another machine to Pyramix LTC out, I observed often a chasing error of e few frame.

I was wondering of course if it was the machine wich had a problem to chase, or if the LTC sent was wrong...

So I did a test: I recorded an LTC out signal, and played back in Pyramix thru the Monitor jack out.
Then I had no more chasing error!

So I went to the conclusion that Pyramix LTC out is not reliable.

Could it be confirmed, and if yes, fixed?


Best regards,

Laurent.

Hi Laurent,

Can you tell us about your config.

What Version?
Do you use a Mykerinos PCI Express X-30?
Do you use a Merging AV case system with MTCHIO?
Did you enabled the playback stall checkbox in all Settings?

Thanks,
Ricardo

Hello Laurent,

some time ago I had similar problems with LTC communication. I had a Sequenzer running as slave to Pyramix, that fed the LTC into the MIDI-Interface of the sequqnzer-computer. I always had periodical drop outs during timecode reading. In order to see what happens I recorded the LTC-Signal onto an audio track. The signal seemed to be o.k. So I fed this audio signal into the Interface and was not surprosed to find it working without problems. Then I realized that it could be a matter of signal level. I set the SMPTE-Generator in Pyramix to a higher output level and all problems were gone....

I just post this in case you have not checked levels yet.

Good luck,
best regards,

Rainer
