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.
4.) Level mode with SAF1 active
Like level mode, the triggered group plays recursively as long as the level of TR pin remains high.
Furthermore, the output control pin SAF1 outputs active signal in response to the active trigger with this mode.
B. Normal triggers and ONEKEY trigger
Normal trigger plays its corresponding trigger group with its own trigger mode. On the contrary, ONEKEY
trigger plays multiple voice groups with random or sequential order selected by mask option. Maximum
ONEKEY play groups, which cannot exceed the total used trigger group, is defined by mask option. By
triggering pin ONE, EM22300 plays groups within group 1 to this maximum ONEKEY play group number.
If the play mode of ONEKEY trigger is selected to be ‘SEQUENTIAL’, the ‘RESET’ function can be
enabled/disabled by mask option. When ‘RESET’ is enabled, user can reset the sequential playing sequence
to group one by triggering the highest trigger input pin (TR12 for other EM22300 bodies).
example (EM22312):
a..) ONEKEY sequential play with "RESET" disabled, the maximum ONEKEY play group is optioned
to be 5:
playing sequence: group1, group2, group12, group3, group4, group5, group1, group2, ... (playing
sequence is not affected although TR12 is accepted).
