I would try all of the following: Turn graphics acceleration totally off. Don't let windows decide performance. Click the "adjust for best performance" option in settings. Set Audition's compatibility to your previous OS. Also, use a different drive than whatever drive your os and programs...
I have the 32 input version of this board. My only complaint is with the so-so performance of the mic preamps. They're quiet enough but are rather "soft sounding" due to poor transient response. Because of this, I use my outboard units for everything.
How hot does the deck plate get while the machine is in operation? If it gets warm to the touch, I would not cover it up with anything. If you have a remote, baffle the machine off once tape is loaded or move it out of earshot where the mics can't pick it up. If all else fails, get some...
There is no way the M30 would add any appreciable delay when doing an overdub
FYI - once aligned, the 38 should be left in sync mode. The repro head is only used for ease of alignment.
I'd check the pinch roller to see if it has a glaze on it and isn't gripping properly. Clean it with a good rubber rejuvenator. Do not use head cleaner.
A corner is not a good place from which to be recorded, especially an untreated one. FYI - The corners are the 1st places I work on when trying to tame a room.
Believe it or not, no JBL engineer/designer had been to a recording session until the early 1970's when one was invited to one at Drew Recording on Lexington Ave. in Hollywood. I cannot remember his name but he shortly later designed the 4315 4-way monitors which is still considered among the...
The 4311 was an update to the 4310. I think that the tweeter is different but am not certain. I would still say that accuracy wasn't part of the design because as I recall, mixes done through them wouldn't translate all that well to other systems. 2nd guessing was the order of the day.
The L-100 was the consumer version of the 4310 broadcast monitor. Fancier box to fit with home decor, same drivers, BUT a different crossover network to appeal to consumer tastes. LA engineers called it, "tizz-boom disease" because of the exaggerated low & top end. The 4310 wasn't all that...
The M30 was pretty good in it's day in many respects but the mic pres left a lot to be desired if one wanted clean, detailed sound with good transient response. Chances are the ones in your current interface perform better. Even the TASCAM techs acknowledged that. If you want analog tape...
There was a similar chip called the 5530 that the TASCAM tech I knew would use instead of the 5532. Supposedly, it was designed specifically for -10 device circuits whereas the 5532 was not.
