Pitch can be off with vinyl control

On Debian, 2.6 64Bit, Mixxx & JACK. Serato CV02
When I try to use real-time vinyl control I get a lag between the rates. I play the same track in software mode (no external control) and hardware (vinyl control). In order to have them playing at the same rate I must pitch up my tables right near +8%. Is this known? I tried adjusting JACK's latency to see if it was some artifact of that but it didn't seem to be. My needles/carts are old, so are my tables.. maybe they're just spinning slow?

I'm turning this into a bug in case I ever manage to reproduce it myself (and so I don't forget about it). We need a vinyl control input level indicator...

Will try to fix this before the 1.6.0 final.

Can't you just lift the code for the timecode scope from xwax?

Yes, we could steal the drawing algorithm, but I think the xwax indicator is confusing and non-intuitive. I'm on the xwax mailing list and there's tons of emails from people with problems and they have no idea what it means when their indicator looks like [blah]. Worst case, yeah, we could steal it... I started coding two embedded indicators in the prefs dialog that you could hack on if you're interested.

Fixed the only pitch problem I can reproduce in r2033.
