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.
Hey friend, I'm working on a clone of the famous EMS VC3, a mechanical matrix is really not easy to build, this circuit presented here is a great option to solve this problem although I won't give up on building the mechanical version first myself. A big advantage of using the MT8816 and a chip programmed with Arduino is the possibility of implementing presets, I see a future in this. A very disappointing detail is that I worked in telecommunications for 25 years and we threw dozens of these MT8816s with ceramic encapsulations in the trash. Regrettable...
that’s why I don’t mind hanging onto all kinds of old circuit boards and things, I don’t consider it hoarding, just preserving inventory until I find a project for it!
@@GadgetReboot Pure truth. I have a habit of saving PCBs and components of all types. I worked at a telephone company here in Brazil, we were discarding many boards, devices and electronic components, I rescued as many as possible and didn't give any importance to the MT8816s, which were just a memory. I'm going to take a chance with some Alliexpress parts.
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
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. 😆
i’m hoping to get time to continue the project over the coming months along with some various effects pedal circuit experiments. I left everything as a mess of wires that needs to be revisited
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. www.pcbway.com/project/shareproject/Dual_Stacked_1_4_Phone_Jack_Breakout_Board_8c83ed54.html 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. www.pcbway.com/project/shareproject/1_4_Phone_Jack_TRS_Breakout_PCB_8e518ade.html
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
