trigger input. The module will record for all the time that the button is pressed
(the trigger input is high) or the memory is full. During the recording time the
LED 'act' will be on. The considerations on the sample rate applies here.
PLAY mode
Whatever you recorded is written on the internal flash memory of the chip and
is available indefinitely (the storage is non-‐volatile) to the user. The 'play'
button (or the jack input) is a momentary (high pulse) trigger that start the
playback of the ENTIRE sample in memory. The playback could be interrupted
before the end by applying another high pulse to the input or a push to the
button. Once reached the end of memory the playback stops and the module
come back to the original state.
LOOP mode
When you press the 'loop' button the playback is started and is held until the
button (or the input) is active. If the end of the audio material is reached, the
playback starts from the beginning, 'looping' the sample indefintely until the
button is released or the input de'activated' (low state, 0V).
AUTOREPEAT mode
(jumper)
When the jumper on the back is inserted, the behaviour of the module is
changed and it will work in a sort of 'beat repeat' mode. When the user presss
the 'rec' button (or the trigger input) the module records the audio material.
When the user releases the button the module will start automatically to loop
the material.
To stop the looping just press briefly the 'rec' button again.
OPTIONS:
•
The jumper on the back of the module, if inserted, enables the
AUTOREPEAT mode for the sampler, as described in the previous chapter.
The default position is 'not inserted'. Please see the next picture:

When the module (the system) is powered-‐up, if the 'rec' button is
pressed and kept that way for at least two seconds, the module reads the
