Softube's Modular, we looked at in a review last year and we were pretty impressed. The level of detail and audio rate mod was surprising. Today we saw the new Doepfer LPG 101 - modelled on the original Doepfer Low Pass Gate. Available as an add-on module, though you can try it out before you buy.
It works in VCA and LPG modes, with three different Vactrols modelled (switchable). Priced at an introductory price of €29 (€39 regular price)
If you already have Softube Modular, its not a bad price.
State of the art for super-wide workflow enhancement
