I have a strange problem when opening 16bits sessions done on TDM Mixplus in PT5.01 on my 001. There appear to be clicks and pops in the files that *seem* to come from the CD ROM's that it's copied from: whether I copy the files in the finder, from my internal DVD-ROMdrive (G4) or from an external (SCSI) CD ROM drive, even if I save the session copy as 24 bits: there in the same place and 'grow stronger' with every edit I do: trimming, audiosuite etc. They sometimes even sound when previewed from 'convert and Import'
To be absolutely sure that it's not my system, I tried opening a session done in my old studio on a Mix system...and I see clicks in the audio...straight from the CD-ROM !!! You know the kind: ditches in sines, spikes, broken waves... WTF ?
I've been trough some posts on glitches and clicks, and I can safely say it's not a clocking problem or drive(r) issue: I never had this with 24 bits session or recordings done @ 16 bits. I reinstalled OS9 (+ update to 9.1), trashed prefs, ran Digitest, removed plugs, changed dither-settings.... nothing seems to make any difference. It's recorded in a respected Pro studio... not very likely to have clicks in their recording...
I need to confirm with you:
- Can a RAM problem cause this (spikes in the same places, even from CD ROM....) ?
- Can otherwise 'safe' waveforms become 'broke' as a result of RAM, cables etc. ?
- Could downgrading the CPU-mixer help ?
- Could this happen during the burning of the CD-ROM ?
I'm in the middle of a big editing session that needs delivery this week...
What to do ?
