II. Trigger inputs
The EM22203/EM22206 provides both normal trigger inputs and the ONEKEY trigger inputs. With normal
trigger inputs, EM22203/EM22206 plays corresponding trigger groups. The ONEKEY trigger, however,
plays trigger groups sequen tially or in random order by mask option. Besides, each trigger input has its own
trigger mode independent to other trigger inputs. Furthermore, debouncing circuits are provided to avoid false
trigger caused from noise or bouncing pulses of switches.
A. Trigger modes
There are four trigger modes which are selectable for each trigger input: level mode, one-shot with retrigger
mode, one-shot without retrigger mode, and level mode with SAF1 active. Trigger modes of each trigger
input are defined by mask option.
1.) Level mode
Under this mode, the trigger group corresponds to the trigger input pin (TR) will be played until the level
of the TR goes low.
2.) One-shot with retrigger mode
Under this mode, the rising edge of TR pin triggers the corresponding trigger group. The trigger is
accepted whenever a pulse is applied on the TR pin.
3.) One-shot without retrigger mode
Similar to one-shot with retrigger mode, rising edge of TR pin of this mode triggers the corresponding
trigger group, too. The difference is that under one-shot without retrigger mode, however, triggers are
accepted only when there’s no voice playing.
