Hi, bought this Wave trigger board because someone said it might do exactly what i needed it to do.

For the price i paid and the GUI i figured it would work. Tried a few things. Might have ran into a roadblock already.

Seems like it’s not exactly doing what it should be doing or lacks what i specifically need in GUI.

Then again maybe just me ??

I lack in programming experience and if i can do this with just this board and perhaps a small Amp “mono 20w max” it would be ideal.

If this requires serial commands it’s just another long headache trying to learn Arduino, At which point i can do a serial based unit for much cheaper.

I’ve tried AdaFruit Mini FX for what i need but my trigger options are limited… and that resorts that to serial based programming which is over my head. I’ll pay someone to program what i need at that point…

I’m trying just generic GPIO in hopes they will do what i need to do.

First question Why does my audio sounds like it’s playing slow, pitch change?? Not right… at all. :o

2nd question I need priority control, which i sorta have a control over… but it’s not exact or something im doing wrong??

Example.

Trigger 1 is a door switch, “HELD/release trigger” Music/chime will play out until the end of the track. “No loop”

Ground will be held even after end of the file in some regard.

Now, IF that ground is held and another High Or Low Triggers i want that one to completely cancel, play a normal non “HELD Trigger” once, then restart trigger one 1 at the beginning without it playing over top of the 2nd audio or starting prematurely.

There’s will be other’s that will do the same.

Video of what im trying to recreate with a quick easy, solution.

I also need a way to switch to stereo outs… “Ground interrupter/Switch ??”

Stereo on the factory box there passes though that box, and IF the music or audible warnings are activated it will deactivate the stereo line and play only from the unit on the front left channel.

Not sure what i would need for that.

Please help me someone… im dragging my feet getting this done with my current skills.

Already spend $100 in boards… trying to find one that works perfectly for my type of Application

Your audio files are most likely recorded at the wrong speed. The WAV Trigger requires you use files recorded at 44.100

KHz. If your files are recorded at a rate faster than that, they will play slower than normal on the WAV Trigger.

2nd question I need priority control, which i sorta have a control over… but it’s not exact or something im doing wrong??

From what I’m seeing in your video, I don’t think you are going to be able to do this without some sort of microcontroller monitoring your inputs and sending commands serially to the WAV Trigger telling it what to do. The WAV Trigger on it’s own isn’t going to be able to process the inputs the way you’re looking to.

I also need a way to switch to stereo outs… “Ground interrupter/Switch ??”

Stereo on the factory box there passes though that box, and IF the music or audible warnings are activated it will deactivate the stereo line and play only from the unit on the front left channel.

Not sure what i would need for that.

Unfortunately we don’t have a product that does this, but you’re probably looking at some sort of mixer that is able to combine inputs and mute one of them when your secondary audio source is playing. I’m not sure who carries these, you might try a store that carries products for custom car stereo installs, or possibly a store that caters to musicians.
