Hello! I’ve got a clone of the Mutable Instruments Shruthi with a Dual SVF board that I can’t get to function properly. I’m fairly confident in my soldering and component choice, and reinstalled the firmware to version 1.03. Everything powers on as expected, but parameter selection isn’t reflected on the main display. I attempted to replace one of the multiplexers to address the issue (I erroneously used a 74hc165E where I needed to use the 165N), but without luck.
Additionally, sound output is a mess. I get a distorted, grinding buzz that changes depending on what parameter page is selected. (I don’t have video of this yet, but I can post it if needed.)
I can provide more photos of the boards if needed. I’m using a generic center positive 12V 5A AC/DC.
