Yup, it’s definitely heavy on the sequencing. Hermod was one of the first modules that I purchased, and I love it. While it’s a capable sequencer, It’s also crucial for me as a midi->CV module and as a modulation source. I also use it as my main clock.
The ER 101/102 combo is more recent in my rack. I’m trying it out for the moment, unsure if I will keep it long term. I think they are fantastic modules, super well built and capable of being programmed in a very intricate way. Was thinking maybe I would replace the hermod with them, but haven’t quite gotten to that point yet. Bit of a steep learning curve.
They are actually really fun to use together, but definitely take up quite a bit of real estate.
