Stabilization period before locking
Although Pyramix is capable of locking to incoming TimeCode within 3 - 4 frames, there are cases where synchro-
nization is more stable if there is a longer waiting time. This is because some external devices take a considerable
time to stabilize their speed after playback is started. This parameter allows a waiting time to be defined before
Pyramix will start chasing the TimeCode. 30 frames is a good starting point if you experience problems with exter-
nal machines.
Silent Chasing (helps large projects to lock)
When checked Pyramix allows large projects to lock immediately while chasing. In this mode locking time does
not depend on the number of tracks. The drawback is that sound only appears one second after a lock is estab-
lished.
Stay in record until stop pressed
If this box is checked Pyramix will remain in record (once properly locked to TimeCode) regardless of disturbances
/ discontinuities in the code until the Pyramix Stop button is pressed.

Allow chasing across midnight

When this option is unchecked the Chase engine always locks between 00:00:00:00 and 23:59:59:2X of Day 0
When this option is checked the Chase engine allows locking anywhere in the Pyramix timeline (-1000 days to
+1000 days). The engine interprets the incoming timecode to be the nearest position to the current cursor posi-
tion, thus allowing chasing around midnight of any days of the timeline.
For additional security and comfort, if Pyramix is in the "locked" state while crossing the midnight barrier, then
even with this setting unchecked setting, there will not be an immediate jump from midnight back to zero while
playing or recording in sync. The playback or recording will remain seamless, uninterrupted and cross the day bar-
rier until an out-of-lock status is recognized. Only then is a re-chase triggered to whatever the incoming Timecode
value is at that point.
Pyramix does not chase external TimeCode
When Hard Chase is active, Pyramix will only playback when valid TimeCode is
detected on the chosen TimeCode input port. If there is a jump in the incoming
TimeCode, Pyramix will adjust to the new TimeCode, re-synchronize and begin
playback from the new TimeCode position. Pyramix will run on its own internal
TimeCode for up to 1 frame if there is a drop out in the time code. If no valid Time-
Code is detected after that time, playback will stop.
When Soft Chase is active, Pyramix will only playback when valid TimeCode is
detected on the chosen TimeCode input port. If there is a jump in the incoming
TimeCode, Pyramix will not adjust to the new TimeCode, but will continue play-
back with an offset from the incoming TimeCode position. Pyramix will continue to
run on its own internal TimeCode for up to 1 frame if there is a drop out in the
TimeCode. If no valid TimeCode is detected after that time, playback will stop.
When the Vari Chase is active, Pyramix will Varispeed, I.e. alter its sampling rate to
follow fluctuations in an external TimeCode. (going back and forth, slowing down,
accelerating, playing normally or backwards, up to 8x nominal speed) while in
playback (not in record)
