If you just wish to have the SX-1 follow the external
Timecode but not send out P2 commands, then you
can just set the HDR Chase mode to LTC SLAVE or
MTC SLAVE directly. In this case, the SX-1 does
not know where to send Transport commands, but
you will be able to do one clever operation by latch-
ing the Record button.
Normally, when the HDR is set to Chase Mode LTC
or MTC Slave, the transport buttons are assigned to
no device. When the external Timecode starts mov-
ing, the HDR will chase and lock, and the PLAY
LED will light solid. In this situation, you can use the
Record button to punch in record channels on the
HDR. If the Timecode was not moving, there is no
way for the SX-1 to start recording. In this case,
pressing the Record button will "latch" your request
to go into record, and as soon as the HDR locks to the
external Timecode, it will automatically do the punch
in. This is useful if you have a project in a PC DAW

go to your PC and press play. The SX-1 will chase
and then automatically record for you.
Note that the SX-1 has a restriction in this operation.
If the external Timecode starts before midnight
(00:00:00:00), then the SX-1 is unable to do the auto-
matic record for you more than 20 seconds before
midnight. In this case, the user will have to wait until
the SX-1 has reached within 20 seconds of
00:00:00:00 before pressing the Record button. Even
in this case, the actual recording will not start until
exactly 00:00:00:00, as no events may start before
that time.
The SX-1's Timecode chase hardware can correctly
follow Timecode that crosses 00:00:00:00 (mid-
night). It does this by treating any Timecode in the
range 23:00:00:00 to 23:59:59:29 as being –
1:00:00:00 to –00:00:00:01. This allows a Timecode
source to preroll and play back over the 00:00:00:00
midnight boundary without the SX-1 jumping for-
wards a whole day.
