Hi. Looking for a push into the right board(s) to be able to achieve the polyphonic playback of two files with a single switch input- one file on the negative going edge, and the other on the positive going edge. The Robertson players are -extremely- versatile and also kinda complex- at least for me when it comes to this problem. What is the absolute simplest way to achieve this? Thanks in advance.
The simplest solution would be One switch , two trigger inputs. When you press the button, One input sees the falling edge. The other one sees the rising edge via an inverter. https://electronics.stackexchange.com/questions/270894/dual-edge-detector
Thank you for your help!
So Iām working with a WAV Trigger board, and due to your suggestion I was able to achieve the same results without the external edge detector circuit by:
Using one button input into trigger 1 and trigger 2
Then setting trigger 1 to ācontact closure / levelā and trigger 2 to ācontact closure, edge (inverted).
The results are- as long as I press the button down it plays trigger 1, when I release it plays trigger 2.
The down side is- at circuit power up it detects an input to trigger 2 and plays that file. Not a big problem for my application, and it is simpler, but I can see how it wouldnāt be ideal for all uses.
I would love to know if there are other, similar solutions that might also work? Bueller?
Annnd, Iām not seeing a way to start and stop a looping trigger with the same input button?
Iām also not finding much on modding the firmware. Was wondering if there might be a solution there?
Again- thanks to anyone that can educate me!
The design youāve described is interesting, but the way it is setup now it is detecting a LOW (inverted) trigger on power which is making things wonky :-/
You can accomplish slightly more complex setups using serial control, as standalone I believe you can set any trigger to play/pause/resume/stop/loop, however I donāt see a method to have the same trigger perform multiple functions (check pg 5 or so)
But you could try ālatchedā mode if you want to prevent re-triggers. For the startup issueā¦Iām thinking with only one switch youād need to use a MCU in-between and wire the switch/button to its inputs. Then set a function that cycles each button press, then that code sends corresponding serial commands to the Tsunami.
These boards have sooo many features that it takes time and a LOT of study to work through the combinations. I REALLY appreciate any help getting there! However, everything has limits, and it seems Iād have to add to the project complexity so solve this one issue. Thatās kind of pushing this beyond itās practicality for my application. Iāll keep going though. Thanks again.

Will throw this in here- a couple months ago, when I started this, I gave this sleuthing task to chatgpt to mull through and find a solution annnnd omgā¦
That thing sounded like it knew all the answers. It did not. If fact it knew less than I did after I perused all the online literature one time and got a LOT of things twisted.
Weāre still safe so far!
Heck, that was months ago though. If I can get it to forget all that and put it back on it it might come up with a more clever solutionā¦
