A timecode slot is an integrated interface that interprets a timecode signal in hours (h), minutes (m), seconds (s), and frames (f).

The grandMA3 can receive up to 16 external timecode signals simultaneously. 

Timecode slots are located in the Timecode Slots pool.

The Timecode Slots pool

Each pool object represents a timecode slot. The slot can listen to external time sources and start counting when a time signal is received. Each slot can also generate a time signal.
