Awesome use case, now you need to set up timing in the sketch and trigger song sequences or have quick programmable buttons with small oleds next to them so you can title the quick button for a specific song, or mix of effects within the song. very cool!
Wow, a practical project!
Inputs, Outputs, Transforms ... Might be nice to have a PC user interface to just draw lines, and make labels on devices so you can quickly configure, load, and save settings.
With any luck, one of your subscribers knows how write a GUI for this.
You are a madman. Very nice work.
if the next project works out I will have definitely earned that title.
Exactly the video I needed for my experimenting!! I ordered the pcb. Looking forward to trying this out. Would it theoretically work to expand further with I/O’s?
I think everything can be expanded including the analog matrix or any more control mechanisms for it although I don’t know if there’s any limitation at some point where multiple chips have to be interconnected and there could be problems introduced running between chips like noise getting in or complications in trying to do signal routing on a circuit board but I figured 16 channels is a good place to start
@@GadgetReboot am I thinking correctly if I assume I have to quadruple the amount of chips to double the I/O’s?
Behringer is (allegedly) currently working on a matrix switcher for their EMS VC3 clone ... I think they finalized their design, but word thru the grapevine was that the mechanical layout for the matrix was difficult to construct and possibly might be, like the original, a feature that is prone to breakdown ... great for testing, maybe not so much for consumption. 😆
Would the chip malfunction if the sum of multiple inputs exceeds Vss?
I was thinking of making a similar set up but using an MCP2221 to convert python to I2C. I am just trying to figure out how I’d handle multiple addresses because the 2221 has an address to write to but so does the MCP23017. The set up would be used as a make shift ATE and the devices that I’d want to analyze have register addresses that are accessed using I2C. I am not sure how the i2c bus would handle everything.
What’s the PCB that you used at the end to connect the 1/4” jacks in?
that’s some thing I made using two vertical stacked jacks with five of them side-by-side. Neutrik NSJ12HF-1 but they’re kind of expensive.

so that’s why I just made the more basic board with the regular jacks and then I can just flip a board upside down to stack them and I can put more side-by-side to extend it.

does this mt8816 chip support serial communication?
I think I sent a 1 MHz sine wave through it successfully although I didn’t try something with fast edges like square waves but maybe I can test that out. I would assume it would work other than just making sure there’s no weird artefacts like ringing on the edges
@@GadgetRebootCan u please check it and confirm it using square waves
