Quoted from PinballTilt:
Question for the club. Does anyone have a pinsound board and a rotten dog mpu on the same game? I’m having issues and am not getting any support from pinsound guys. Wondering if this combo works for anyone. Thanks
I do not own either board...however I have been looking around considering a pinsound for my JP. One thing I noticed is they have an accessory available for data east if your power supply is aging / low voltage at the board. I would check your voltage and get this accessory if low or I've heard some people installing a second powersupply just for the pinsound/other mods as they draw power and add up. https://www.pinsound.org/shop/index.php?id_product=41&controller=product&id_lang=1 I've heard similar complaints from people installing ColorDMD and drawing more than normal off the one voltage segment.
If your regular sounds are working, and not the remix (or vice versa) it could be a either a bad/incorrect/corrupted mix stored on the USB or potentially act different due to voltage as the usb controls gains on different sounds/music and could be drawing different power or hitting that threshold of the voltage if it's right on the edge and the studio data cranks it up a notch.
Not an expert, but throwing my 2 cents in as something to try
Also if someone is considering selling their Pinsound, I may be interested.
