Digital I/O
When DIO•8 or PDI•8 cards are installed in the HDR24/96 I/O slots, a pulldown menu will
appear for each installed card. Setup options for each card are addressed in the Quick Start

Locator-MMC – Tempo Map and Tempo settings
This is a multi-function menu with functions described in detail in Appendix A. The tempo for
BBT scale calculation is set from this menu. A MIDI file with a tempo map can be loaded
from this Setup window, to allow the BBT display to follow tempo changes when the
HDR24/96 is synchronized to a MIDI sequencer. Song Offset (page 16) and Preroll (page
37) times are set from this window, as are device ID’s for MIDI Machine Control.
Sync
This menu contains setup parameters for sample clock source and rate, bit depth, time
code source and framing, activates time code output, and allows setting of time code offset.
Appendix D contains detailed information about both time code and sample clock
synchronization. All of these parameters can be set from the GUI menu or from the front
panel using the SYNC button.
Sample Clock
