chromaprint VS OTTO

you could always cut up the video into segments A,B,C,D,E using like ffmpeg -ss 00:00:00 -t 00:10:00 -i input -c copy A.ext (where A is the first 10 minutes of video) and then recombine with https://trac.ffmpeg.org/wiki/Concatenate, might take a while though and some basic math. maybe you could do something programatically with chromaprint by identifying the repeating audio segments? that's just an idea since that's what this jellyfin plugin does to identify repeated segments of shows in the form of opening credits.

I'm currently doing the same. I'm using the chromaprint library via the pyacoustid library, using the technique described here, which should give a certain amount of leeway in terms of pitch and other variables. See also the notes in the chromaprint documentation about truncating the samples to reduce noise.

There is a music fingerprinting project called Chromaprint. The fingerprints generated by this library are widely used in music database, including Musicbrainz.

Are you aware of the OTTO project?

I'm surprised no one mentioned OTTO. It's literally a diy op-1 clone... That seems to be just turning into its own cool thing, rather than the original concept of straight cloning the op-1 https://bitfieldaudio.com/

I was only able to find the OTTO - Are there any others?

Like this? https://github.com/bitfieldaudio/OTTO

This was born as an accessible replacement: https://github.com/bitfieldaudio/OTTO

This thing is definitely not the OP-1 firmware. OP is either displaying a static image, or something they created that just resembles the OP-1 string synth. At first I thought it may have been graphics from the OTTO project, but I can't find anything to support that.
