    Ok. I have built the cable. I have double checked for opens and
    shorts about 30 times now. I follow the setup procedure for the
    ES-50. (Hook everything up and press the Setup button.) I get Cubase
    SX to generate SMPTE via the SMPTE Generator plugin. I record that
    onto track 8 of the TSR-8. I have SMPTE from Cubase coming out of an
    analog output of the soundcard into the Master TC of the synchronizer,
    and SMPTE from the tape deck coming out of track 8 into the Slave TC
    of the synchronizer. I start both Cubase and TSR-8 from 0:00, wait a
    couple of seconds and hit 'Chase'. TSR-8 goes into rewind until tape
    spools off.

    Of note, in an earlier attempt at this I had an open in my cable for
    the Ext/Int pin. This prevented TSR-8 from being servo controlled by
    synchronizer, so obviously I couldn't get a lock. However,
    synchronizer was able to FF/RW tape deck, stepping at regular
    intervals to see where it was in the TC until it was in the general
    ballpark of Cubase. So if I "rewound" Cubase, TSR-8 would see
    discontinuity in timecode and back track to more or less the same spot
    as Cubase. While chasing without the servo control enabled I could
    watch the indicator telling me the tape deck is behind, then the
    'lock' indicator comes on, and then the 'ahead' indicator comes on as
    the tape deck passes the computer. Telling me that the synchronizer
    is indeed comparing and understanding the timecode and can tell when
    they match.

    So then I fix the cable to enable TSR-8 to allow external servo
    control. This is the point that tape deck rewinds as soon as I put it
    in chase. Anybody seen this before?

    Other strange observations:

    - When only Cubase is outputting TC the 24fps light flashes. Even
    though plugin and timeline are set to 30fps. When only tape deck is
    outputting TC the 30fps light flashes. When both are running both
    24fps and 30fps lights flash. This occurs also if through tapedeck
    into input monitor so that it is actually just passing the TC directly
    from Cubase. Wtf?

    - If I start Cubase from 0:00, clock on SMPTE plugin display clock
    starts at 12:25:39:00 (hh:mm:ss:frame). If I start Cubase from any
    point after 0:00 SMPTE
    display clocks is synchronous with Cubase transport clock as one would
    expect. Again, wtf?

    - I've rerecorded the TSR-8 SMPTE track by clicking on 'Generate' on
    the SMPTE generator plugin and recording that signal. I've also tried
    recording the signal coming off plugin when in 'link' mode and putting
    Cubase in 'Play'. (Should be identical right?) I've tried starting
    at 0:00 and at 0:30 in case above 12:25:39:00 weirdness is a problem.
    Results are identical in each case. TSR-8 rewinds as soon as "Chase"
    is pressed.

    - CoolEdit claims to have SMPTE synchronization but it's clear that
    they really mean MTC, since you have to use a midi port for it. Why
    don't they just say MTC? Their documentation propagates rather than
    clears up the confusion between the two.

    Anyway, if this sounds like something somebody's seen before and they
    remember what the problem was, please let me know.

    Thanks for your help,

    Ok, I can't reply to my most recent post because it hasn't shown up
    yet, but it fucking works. I don't know what the fuck I did to fix it
    but it fucking works. I got vocals on tape and guitar on computer and
    they sync up great. For shits and giggles I tried playing back same
    guitar part on computer and tape together and result was good and
    phasey, like I would expect. Could be neat effect if done on purpose.
    A more subtle and less annoying flanging effect.

    But shit. It fucking works. My roommates are asleep so I can't make
    anyone bask in the glory of it all.

  3. Is there a setup page in the synchronizer where you specify what tape
    transport it is going to control? This is very important in getting
    my Zeta 3 to work.
