To recreate Elektron gear with Eurorack modules 1:1 is IMO not possible yet. Coming close to it, which I think is possible making certain compromises, is very expensive. Assume cost of 5 to 10 times more.
The major difference for me are the Elektron sequencers. The kind of easy p-locking so many parameters and saving it out as a pattern or project is hardly achievable with modular sequencers.
IMO one modular solution coming close to the Elektron workflow is the combination of WMD’s Metron and Voltera. Metron is a matrix trigger/gate sequencer and can be extended by Volteras, which provide 4 CV channels each.
Just to have a suggestion of cost:
- 850 EUR for one Metron with 16 trigger/gate tracks
- 300 EUR for one Voltera with 4 CV tracks
For 16 trigger/CV tracks we would need one Metron and four Volteras and pay 2050 EUR. This would make no sound and have no case and power supply.
I suggest also to compare - as an example - the functions of the Techno-System of Erica Synths with one of the more recent models like A4, AR, OT, DN, ST etc.
IMO Eurorack modular shines, if the flexibility of patching with cables is required and the objectives of the artist can’t be achieved otherwise. On the other side we get more functionality for less money using Elektron devices.
