3.9- The “Tracks.txt” File: The next image shows an example of a
standard “tracks.txt” file needed for the processor to correctly mount
1 to 10 tracks in the channels for polyphonic modes 1, 2, 3, 5 and 6,
and to play single audio files in monophonic mode 7 in the 1
st
working
manner.
This “tracks.txt” file must be placed in the microSD card root path
together with the .wav files written in the contents of the .txt file.
Example of Standard Text (*.txt) File Named “tracks.txt”
In polyphonic modes 1, 2, 3, 5 and 6 the processor opens and read
the contents of the “tracks.txt” file, and mounts each read .wav
file/tracks (1 to 10) in their respective channels, then those are ready
to be triggered with each one of the 10 physical inputs pins I0 - I9.
In monophonic mode 7 1
st
working manner the processor opens and
read the contents of the first .wav file, mounts this and then it is ready
to be triggered with the P/P (play/pause) input button.
* Please note that the ‘/’ slash character can be used in the tracks.txt file contents
to denote folder nesting, in the above image example, the Rooster.wav file is
under Nature/Animals folder.
* If no “tracks.txt” file is found or if the file read has no valid .wav files an audible
message “No WAV tracks” will be triggered in the SmartWAV 2 audio outputs, this
message could be avoided by programming a register in the Standard Serial
Mode 0, refer to the SmartWAV2-CommandSet.pdf for more detailed information.
