Alesis ALESIS M20 owner manual Tape TC Detection in Fast Wind Modes

M20 Software Version 2

∙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.
