Editing M20 Parameters, Chapter 3

3.2THE EDIT BUTTON

The Edit button toggles the M20 in and out of Edit Mode. Enabling Edit mode (button lit) allows editing parameter values for the functions grouped with the Edit button: Track Delay, Tape Offset, SMPTE Chase, Internal Gen, Format, Pre-Roll, Post-Roll, Auto Return, and Auto Record. While Edit is On, only the currently selected function’s switch will light. However, the M20 retains the current on/off status of all switches, and these become visible after exiting Edit mode.

Note: Don’t be confused! Editing a function does not turn it on. For example, while editing the Post Roll value the Post Roll switch will be lit, but if the light goes out when you leave Edit mode, Post Roll is not yet active.

If the Edit LED is not lit, pressing the various switches toggles these functions on and off. Example: If you’ve used the Edit button to edit the amount of Tape Offset and the Edit button is off, turning on the Tape Offset button enables the programmed amount of offset.

Pressing the Display, Pitch Value, or Utility button will also exit Edit mode and enter the Display, Pitch, or Utility pages, respectively.

3.3EDITING CONVENTIONS

∙The rightmost 7-segment display shows locate times in hours, minutes, seconds, frames, subframes and samples. Subframes equal 1/100th of a frame and range from 0…99. The number of samples per subframe depends on the Tape Counter and Sample Rate settings. If the tape counter is in ABS Time mode, there are always 15 samples per subframe in 48 kHz and 14 per subframe at 44.1 kHz. If the counter is in a SMPTE Time Code mode and the sample rate is 48 kHz, Sample steps range from 0 - 15 for 30 frames/sec, 0 - 15 or 16 for 29.97 frames/sec, 0 - 18 for 25 frames/sec, and 0 - 19 for 24 frames/sec.

∙A lit arrow above the subframe (SF) indicator indicates that there is a non-zero sample value. To access the samples field, with the subframe field selected press the Right Cursor button. This selects a second page that shows only the sample value.

∙When editing any tape address, the cursor steps in fields (hours, minutes, seconds, frames, subframes, and samples) instead of stepping every digit.

∙When editing any tape address, entering digits with the keypad automatically advances the cursor or selected field (using the Up/Down Arrows does not advance the field)

∙When editing a field in the 7-segment display, the digit(s) of the selected (and currently editable) field will flash.
