I guess I don't understand what you and Jovinyl mean by splits. I thought you guys were talking about some problem with the autotrack feature.
I have A-Track off.
So I never have any problems with quiet moments triggering an incremental Track no.
When one side of the LP ends for Track 1, I hit Pause.
Turn the LP over for side 2.
And restart recording for Track 2.
What kind of "split" problem is difficult to get right?
I leave A-Track off too after messing with it and discovering it is not accurate. The OP used the word "split" to mean separating tracks. My problem with the A-Track on the 900SL is that while the trigger frequency is adjustable (another nice touch from Tascam, I mean that in a good way), it doesn't trigger correctly most of the time. One has to set the sensitivity rate very high to get it to work 99% of the time and then when it does, it tends to track split at every single silent or low volume section that is 2 seconds or longer. (Yes, the manual does pint this out). So if a song has a part that dips above the threshold setting it creates a new track and you also lose the first 2 to 3 seconds of the new recording. If a song has a truely silent section that is 2 seconds or longer the same thing happens.
That's why I just leave it off. To me it doesn't matter to have it off, because I record to CDRW then throw that into the computer, rip it to lossless wav, run it through Audacity, split the tracks and export. That way I don't have to babysit much during recording, except to monitor the levels. (It's just like using a tape deck except that being digital, one needs to set the input levels a little lower than one would with tape, digital is more sensitive to clipping). If I want to separate tracks during recording I just do it manually which requires more monitoring of course.
