Recording a Sample / Audio Loop-Through Mode

Recording a sample and audio loop-through is accomplished using the deMIDulator's “

Sample 

Record

” button.

Pressing and holding this button in any mode will cause

:

all of the waveform LEDs to illuminate

the currently selected audio input source to be looped through the device to the headset jack 
output

Note that MIDI input is still processed while audio loop-through is active.

After releasing this button in Sine and Square modes:

previous LED function will resume

audio loop-through will stop

normal playback function will resume

After releasing this button in Sample mode:

the deMIDulator will begin to record and save an audio sample from the selected audio input 
source

all three waveform LEDs will remain illuminated while the sample is being recorded

audio loop-through will remain active for the duration of the recording

the recording can be cancelled by either waiting for the maximum sample time to elapse or by 
sending the deMIDulator a MIDI Note On message. This allows you to customize the length of 
your sample.  Sending a MIDI Note On to cancel the recording will also cause the sample to 
begin to play back immediately.
