M20 Software Version 2

M20 ADDENDUM 2.1 MA-3

Using Tape Offset mode.
1. Tape Offset is enabled, ID 2’s tape offset value is non-zero and user tries to take ID
1 offline:
ID 1 offline is not allowed and “ID 2 Tape Offset Not Zero” is temporarily displayed.
2. ID 1 is offline, ID 2’s tape offset value is non-zero and the user tries to enable Tape
Offset:
Tape Offset enable is not allowed and “ID 2 Tape Offset Not Zero” is temporarily
displayed.
When ID 1 is put back online, all slaves will stop. CADI and slave memory is updated
to be consistent with ID 1 parameters.
All Machines Offline
If no machines are online, then the CADI will display “No Machines Online” when any
action is attempted.
Special notes when operating a CADI with ID 1 offline
No SMPTE Chase
SMPTE Chase remains a function of the ID 1 machine. ID 1’s SMPTE Chase parameter
settings are reflected on the CADI display even when ID 1 is offline. When ID 1 is
offline, SMPTE Chase for the pseudo-master and remaining slaves is not permitted.
Internal Generator operation
ID 1’s internal generator parameter settings are reflected on the CADI display even
when ID 1 is offline. The pseudo-master’s internal generator will operate, but its
output is subject to its own internal generator parameter settings (which may differ
from the ID 1 settings). Therefore, in most situations, time code generation should
remain a function of the ID 1 machine.
TAPE TC DETECTION IN FAST WIND MODES
Detecting discontinuous and noncontiguous Tape TC in fast wind modes has been
implemented. The M20 will recognize TC Track time code discontinuities and time code
gaps in fast wind modes, i.e., when chasing time code or during a locate, scan, search, fast
forward, or rewind). In addition, when Rew/Fwd TC Out is on, time code accurate with
the TC Track will be present at the M20’s Time Code and MIDI Outputs in fast wind
modes.
Please note that for speeds less than 1X (one times) play speed, the Tape TC is extrapolated
from the last valid reading.
