its there a way i can create a envelope using the cv steps or maybe something that can be add in mod?
You probably could, by tediously producing a series of different voltages on adjacent steps, but it would be crude and lacking temporal resolution- and a pig to edit.
Eloquencer is a Eurorack module, and luckily Eurorack is full of function/envelope generators. In modular it makes a lot more sense to do things like that elsewhere, generally.
Have a look at the Klavis Quadigy, Intellijel Quadrax or Mutable Instruments Stages for a start- they're all really good, usable and feature-packed as well as being HP-efficient. If you're feeling more lavish, you could always look at Make Noise Maths, of course.
