Alesis ALESIS M20 Tape TC in the Tape Counter, Fixed Mode Time Code Generation TC Start REF, MA-4

M20 Software Version 2

Note the following exceptions when using tapes previously formatted with v1.xx software:

∙When a version 1.xx formatted tape has tc recorded to it using version 1.xx software, time code discontinuities and non-contiguities in fast wind will not be recognized. In this case, the M20 will extrapolate time code values when in wind modes (based on the last valid tape tc detected in Play or Record mode).

∙When a version 1.xx formatted tape has tape tc recorded to it using version 2.xx software, time code discontinuities will be detected in wind modes. However, time code values will be extrapolated when a section of tape without time code (noncontiguous time code) is encountered while winding. Once Play or Record is pressed, the actual tape tc value (if present and different) will be detected and properly displayed.

TAPE TC IN THE TAPE COUNTER

When the Tape Counter selection is SMPTE, the display is now based upon the chase reference selection:

∙When the chase reference is ABS Time, the display shows the ABS Time plus SMPTE Offset value, as before.

∙When the chase reference is TapeTC, the display now shows the Tape TC plus SMPTE Offset value.

When Tape TC is selected as a chase reference and no Tape TC is detected on tape, the Tape Counter will indicate “no tAPE tc” when in SMPTE mode.

FIXED MODE TIME CODE GENERATION: “TC START REF:

FIXED”

The internal generator’s TC start reference parameter can now be set to “Fixed”. When in Fixed mode, the start offset does not update to the last generated value when time code generation stops as is the case with User Set mode. Fixed mode will maintain the same start offset value after generation stops, i.e., the start offset value remains fixed, therefore, every time generation is restarted, time code output will always begin with the same start offset value.
