I have already tried Zadar in a music shop in connection with different oscillators. The module is a lot of fun. For simple modulation I've always used Ochd and Maths. If I decide to buy Zadar I am considering taking Maths out of my case. Except for modulation, I actually use maths as an attenuator or simpler things. I still have Samara for these functions. I know that maths is the module for many but just because it's very common doesn't mean it's for everyone. I think that's the nice thing about Eurorack. If I notice over time that I'm missing a function that Maths can do, I still have space for modules that replace it. Does anyone have experience with Noise engineering´s Pons Asinorum compared to zadar?
