Wav Trigger with banks

Hmmm I haven’t seen that. What are you using to generate the gates?

Is there a schematic for the WAV trigger? It sounds like there’s a capacitor that has to charge to trigger a HIGH state on the MCU and that several concurrent triggers are not giving the capacitor enough time to discharge to trigger a LOW. That’s just a hypothesis though, I’d need the schematic to say any more.

Hey Zorch!

if you were to press and hold one of your buttons, would it continuously play the sample, or just play it once? I’m working on my build and my samples are playing sipe ready back to back when I hold the button and it’s annoying :man_facepalming:t2:

I’ll have to give it a check, but I’m pretty sure it would just play it the one time.

That would be awesome! I wonder if it’s because I’m not using any resistors :joy:

Yes, holding it down does not re-trigger the sound.

In addition I am only able to retrigger sounds fairly infrequently, which is something I have been meaning to look into.

Hey everyone! I’m having some trouble with my wav trigger and I’m looking for some assistance.

Full disclaimer -

  1. I always have to do everything over the top and complicate things way more than necessary because frankly, I’m an idiot

  2. I have no idea what I’m even really doing. Again, I’m an idiot

Photos of the wav trigger below




The idea for my wav trigger - two banks of 7 samples each. Banks can be controlled by the buttons to the far right. Samples can be played by pressing the button or by CV - both methods will result in the LED in the button flashing.

The problem - the 2nd button from left will not play a sample or even light up when triggered through CV. The sample will play fine when the button is pressed.

The other problem - the 3rd button from left will not light up, but will play samples fine through button press and CV.

Does anyone have any idea what might be going on?

Can you share what config you loaded? Maybe that’s why?

Sure! This is the .ini that I’m using. I haven’t configured the banks yet

There are some simple things you can start with:

1: You might want to check whether the lights of those buttons are in working order.
2: Can you check that there is a voltage present to light the button when it is supposed to be? You can check that with another light you know is working (or an LED with a resistor in series), which should then light up.
3: Apart from visual inspection, you might want to measure whether all points that seem connected by cables are in fact connected.

Thank you for the tips! Tried all of these and unfortunately I still have the same issue. I might disconnect everything and start from scratch :face_with_spiral_eyes:

Take the wavtrigger out and just try manually triggering

This will def elim the other bits from being the problem, good troubleshooting step!

Definitely going to try this!

Finally getting around to working on this - but not having luck for some reason.

Here is my .ini:

#TRIG 02, 2, 1, 1, 1, 1, 1, 0, ,

#TRIG 16, 2, 1, 1, 0, 0, 12, 0, ,


And this is what my file structure looks like

The first bank seems to play fine - but the banks dont shift when I trigger 15 and 16

Maybe the text files messing things up?

Quick update - I took out the text files and now it seems that the triggers cycle back and forth between banks, but the new banks are blank and dont play sounds when triggered.

Maybe they are not “woke” enough to be easily triggered

I think I have narrowed it down to some bad sound files. They play fine and seem to be in the correct format in audacity - but when I load them into the trigger they don’t play.

try not using the txt files. in my github there is a python script that will make banks for you, including padding with empty wav files.

It also includes the ini file i use.

I was reading back through and got a lot of help from past us. Its a little upsetting how many things I forget.
