I have made sure that all the tracks are panned towards the center, but no audio comes from the right channel. If it is plugged into speakers or headphones and panned to the center, audio only comes from the left side. If it is panned to the right no audio come out. I was curious as to if there is something I am missing or if this is a hardware problem that requires repairs/parts. Thanks!
You most likely have your External sync set to pocket operator sync. See section 10.7 in the Op-1 manual. It uses the right channel to send sync data, therefore no audio will come thru. I did this once already and was baffled for a few days, I almost bought a new board even!
If the above doesn’t work try wriggling the jack in the socket to see if the contact has come loose from the control board. If it has come loose, you may need to re-solder the audio output component’s contact(s).
I resoldered mine with a decent iron and yeah it’s quite difficult because of the component size and proximity to other components. Even with a decent setup I made a bit of a mess. I’m used to welding too haha. If you’re able to do it you can save $50+ on a new control board. If you’re not comfortable the price for a new control board can be worth it. That said, it’s worth a shot. What are you going to lose if you mess it up with a cheap iron? If you get it right you get a functioning OP1. If you mess it up you have to fork out, which is what you’d have to do anyway.
