You are touching on an interesting point.
If I am not mistaken, in the times of the MD and MnM, Elektron only had a line of 3 products. So each of their product had incredible deepness to them which a quite cumbersome workflow.
Right now, more than 10 years later, Elektron has a line of 10 different products. Organized in different price categories, and with fairly different workflows.
What features each product had in the past line of products obviously are more diluted now in the 10 products that Elektron still support. And the idea is probably to have the customer buy more products to get the full scope of features they want.
In the case of this new AHFX maybe the idea of no sequencer on the box itself was because they wanted the customers to use it with a digibox that could sequence it? Maybe to boost the sales of the digiboxes?
Not to say that Elektron product quality is bad. But obviously there is a conscious decision to not overlap features between products and I do not think it is only for the customer best interest.
