Adafruit Audio FX Sound Board play random Moderators: adafruit_support_bill, adafruit

I have a Adafruit Audio FX Sound Board and want it to play a random song out of a series using the T01RND1.wav etc. file type. I would like this to occur on power up on the board so I shorted Pin 1 to ground without a switch. It doesn't seem to do anything at this point. It randomly selects a song if there is a delay between power up and grounding of the pin only. Is this the only behavior for this RND access to songs or do I have other options to have grounded pins on power-up.

Thanks

I just checked the board's behavior and that should work. I was able to have several random tracks play at power up via a shorted pin.

Double check your filenames. It should be RAND not RND:

Did have an issue with naming! Thanks for that but when I ran the demo files I found it repeated the same sequence every time I triggered it which results in it playing the same initial
file every time...not random really just a sequence. This would work if you left the machine on and kept triggering it but just turning it on results in the same song every time. Is this your take on it or am I missing something again?

So if you have something like:
T01RAND01.wav
T01RAND02.wav
T01RAND03.wav
T01RAND04.wav
it will play randomly.

BUT - it does the same "random" sequence each time it is powered?

Yea the download files go “voice 4,3,0,,1” in the same order every time u power it on...

[adafruit_support_carter]

I'm seeing the same general behavior. It's probably a limitation of whatever the random generator is on the Audio FX Board. It must be pretty simple and doesn't do any kind of power on seeding to truly randomize it.

Very much appreciate your help. Ordered a couple of the feather sound boards Instead to get better control in the project...hope Adafruit Does ok!!

[adafruit_support_carter]

Thanks! And we hope *everyone* is doing OK also.

What Feather product(s) did you order? The Feather line has main boards and add on boards called FeatherWings. Want to make sure you didn't buy just a FeatherWing without a Feather to control it.

Bought a couple of these: MUSIC MAKER FEATHERWING along with a couple of poto boards 32U to control them...never used these particular wings but there are a couple of new demos up on your website that looked like the libraries worked.

Ah, OK, sounds you got some of these?

That'll work fine. Just wanted to make sure you didn't buy only the FeatherWing thinking it would work stand alone similar to how the Sound FX board does.

Another thing you could try is using the Feather 32u4 to control the Sound FX board via its Serial Control feature:
