As in algorithms? Nothing in the current lineup to indicate this is likely. Octatrack remains the only outlier there.
I don’t know if AH+FX is still on the “old” platform (hate saying this phrase, and I think this is heavily being misunderstood also in the context of speculation) - someone would have to open up their AH+FX and take a pic of the PCB. Digitakt II and Digitone II have a new SHARC DSP onboard that supposedly serves with more future expansion in mind. Realistically no one but Elektron knows the answer to that.
