Ah, you are probably right - I forgot about those extensions and hoped there would be the time and the opportunity to revise the OP-1 now that the OP-Z is finally getting released. I have to say I did not follow the OP-Z story too closely though because I can’t see me getting along with the UI.
But I just watched the oplab-series tutorial videos with all the additional controllers and have to say that it is a pity that it did not make it cause it looks like a lot of fun.
