Hello During a 3 week session at Air Studios in London we have found some serious sync problems with LAMP when syncing to MTC. The senario is as follows: Beige G3/266 UW scsi drives (Apple drivers) MOTU 2408 with Appoge A8000 24bit convertors x3 LAMP 4.07 (4.02/4.04/3.72 also tested) Unitor 8 mk2/MOTU MTP AV (we tried both) Sync setup: Studer MTR resolved to house sync (Video PAL) MOTU 2408 resolved to house word clock 44.1Khz Appoge A8000's resolved to house word clock 44.1Khz Unitor 8 mk2 fed smpte @ 25fps or MOTU MTP AV resolved to house word clock and fed smpte. LAMP: Set to MTC Audio sync to EXTERNAL OR FREE (we also tried MTC TRIGGER and DIGITAL) The problem: When recording audio from tape via the A8000/2408 the resulting audio file never ends up in the same place in LAMP. We passed the same drum track from the tape 10 times whilst syncing to MTC and EVERY pass was different by as much as 50ms! (2200 samples) The average descrepency was arround 30ms. The resolution of MTC at 25fps is 1/100s or 10ms but we could rarely acheive even that. Because the timing varies from pass to pass we had no choice but to stop using LAMP for any timing critical tranceferes to and from tape. Using Protools software and hardware with the MTP AV doing the MTC sunc resulted in approx 7 samples delay on average! We also found, to my surprice, that the MTP AV had a more solid sync to MTC than the Unitor8 mk2. The Unitor drifted slightly around the beat where as the MTP would lock very tight. For the record, this is not an issue with analog tape versus digital as the same problems occured when striping a DAT with smpte and running that in place of the Studer MTR. (the DAT was resolved to house word clock). Conclusion: Well this is where we need some input. Is this an issue with LAMP or ASIO or both? Have we made any mistakes within this setup that would explain these problems? Does Emagic or MOTU have any comments? the session continues till December 12 so any help or thoughts would be appreciated. Mads Bjerke
