I don’t know why people keep spreading this baseless assumption.
Elektron has never advertised or pushed buying another one of their boxes to get certain features that others are lacking. Each item is treated like a separate instrument, it’s own idea. There is never really even mention that the boxes work well together through x, y, or z feature. Hence, the reason there is a lot of topics on this forum about getting the boxes to play well together.
Additionally, almost every one of their products gets additional feature after release until the hardware is basically maxed out on what it can do.
Things will likely be added to the dt, as has already been seen with the compressor, but I highly doubt the dt will get more OT like. And this is not because or sales but rather the instruments are two entirely different ideas.
