I have this strong belief that Elektron are going to release a slew of machines similar to the Digitakt. I think the new strategy is to modularize the units they produce to a further degree while ultimately lowering the cost for each unit.
I think that there will be units that offer different specialties including different forms of synthesis, and effects processors similar to the AH. Since the units will be less costly and smaller, they’d be ideal to combine in different ways like Eurorack modules.
The soon to be released DT is literally what it is. It is not an OT replacement. There will likely be an actual OT replacement that will be more expensive and bigger.
Basically, the AH and DT are the first of Elektron’s “Modular” line of devices. They’re more limited and focused for specific purposes. There will be many more. But there will also be an updated OT soon imo.
