Bob invited the iconic filter chip designer Dave Rossum to our booth at NAMM to talk about his filter designs. Caution: It gets super nerdy! In the video, Dave shares the incredible story about how he came up with the design for the 2040 filter on a napkin over lunch with Tom Oberheim, how he avoided stepping on Bob Moog's toes when designing the 2144 filter, and what the sonic differences are between these two chips.
