Trigger Modes / Function Settings

There are 7 main trigger modes(from “0”to “6”) and 5 assistant trigger modes(from “7”to “B”) available for users to set in a configuration file according to the actual needs

Each of the parameters from “0”to “B”represents a corresponding trigger mode, which an be set individually for each of the 6 trigger inputs. See the details below.

Detailed Explanations on the Main Trigger Modes 0-6

· Pulse Interruptible: In this mode, a single negative pulse will start playback. It is possible to interrupt the playback by pressing the same button used to activate. Once playback is interrupted,it will automatically restart the audio file immediately. It’s also possible to interrupt the play back by pressing any of the other 3 buttons. Once playback is interrupted, it will automatically start the sound that is associated with the button pressed.

· Hold and Play in Loop: In this mode, the negative pulse must be held/maintained to the sound module trigger for audio file to complete. The audio file will only playback while button, or negative pulse, is held/maintained during playback. Once the button being held, or negative pulse, is removed, the playback will be stopped/cancelled. Once the button is kept holding, when the playback of the audio file is finished, it will start to play it repeatedly(loop playback).

· Pulse Non-interruptible: In this mode, a single negative pulse will start playback. It's not possible to interrupt the playback by pressing the same button or the other buttons. Once an audio file is triggered, the audio file will not be able to be interrupted/cancelled during playback. The playback will only end when the audio file has played its entirety.

· Hold and Play Once: In this mode, the negative pulse must be held/maintained to the sound module trigger for audio file to complete. The audio file will only playback while button, or negative pulse, is held/maintained during playback. Once the button being held, or negative pulse, is removed, the playback will be stopped/canceled. Once the button is kept holding, when the playback of the audio file is finished, it will not start to play it again.

· All in Loop: In this mode, a single negative pulse will start playback. Press the button and it’s able to play all the audio files in the storage device one by one in loop. During playback, if the the same button is pressed again, the playback will be stopped. In addition, if the associated trigger input is shortened with GND first, the player will automatically play the audio files one by one in loop once it is powered on.

· Play Next in Associated Folder: In this mode, a single negative pulse will start playback.Every time press the button and it’s able to play next audio file and stops when the audio file is finished in the associated folder. During playback, if the the same button is pressed again, the playback will be interrupted and it will activate the next audio file at the same time. In this mode, as many as 100 audio files can be loaded into the folder.

· Single in Loop: In this mode, a single negative pulse will start playback. Press the button and it’s able to play the associated audio file in loop. During playback, if the the same button is pressed again, the playback will be stopped.

Any of these 12 work modes can be set for any of the 6 trigger inputs through a configuration file named “read.cfg”, which comes from a text file(.txt) originally. In the configuration file, each digit that represents the work mode is associated with one trigger input, so there are total of 6 digits that associate 6 trigger inputs respectively.
