Teenage Engineering OP-1

The fabled OP-1 from teenage engineering has to be one of my favorite instruments in the last decade. I’ve included photos of a my recent logic board repair to resolve an issue recognizing the OP-1 in Ableton Live.

Key cap removal is an essential part of repairing the OP-1. iFixit’s guide provided a few instructions, until I found a forum thread (maybe at elektronauts?) that included a full teardown of hardware that needs to be removed before attempting to lift up the keyboard and replace the logic board. Tools like exacto knives (flat) and tweezers were super useful for safely removing the key caps. A Phillips 00 also worked perfectly for disassembling most of the synth.

Super cool Teenage engineering included an on-board diagnostic for testing your synth!

After replacing the I/O board in the OP-1, I suspected a logic board may be the issue, so I went ahead and gently lifted the keyboard after removing the keycaps to reveal the OP-1’s gorgeous interior design. The device has very few connectors and the body seems like a tank. Proceed at your own risk here, as many of the components appear to be super fragile. I replaced the logic board successfully, but Teenage engineering accidentally sent a locked version of the DSP. Shortly after receiving another logic board and shipping the old back, I was in action again. The logic board replacement fixed the USB issue.

The op-1 can do so much: midi, sound design, sampling, recording, radio, and tape editing. I was happy to know the designers at Teenage engineering placed as much detail in their industrial design as they do their user menus. The architecture is stunning (if you’re lucky, I’ll find a snap of the Manhattan breadboard). Since the repair, I’ve been focusing on swapping original samples for the stock sounds and created some absolutely radical sounds out of the OP-1. There is a rich, digital sonic character that reminds me of the Blackfinn DSPs built into older high-end synths and soundcards of yesteryear. There isn’t much room for lining up stock samples, and I found the recommended software solutions on the teenage engineering website minimal at best. However, if you’re ok with a few analog drums and some big synth patches, the OP-1 most likely has more than enough an aspiring musician could need on tour. The 1/8th inch connector out is limiting in the studio, and the features like recording and tape editing seem to lack the tempo matching capabilities of Ableton or Octatrack (although, the TE store offers an interesting platform called OPlab for CV, Stereo, and Midi Sync expansion to the OP-1). Highly likely, the omission of full size audio ports was to preserve the authenticity of the OP-1’s nod to old Casio SK samplers.
