Buchla Thunder as Mixer

Hello all,

Right now I’m trying to utilize one preset of the buchla overlay as a mixer (with midi cc slider) and I find that the tracking action and response are not precise enough to my requirements - meaning that whenever I push it up from 0 value I’m not able to accurately reach my intended value everytime (eg: from -inf db to 0db) - also maybe because each of the slides are different in size? it would be great if anyone can offer a workaround. Thanks!

Also, I was able to achieve accuracy with the G and L slides - I’m wondering if the other sliders can be somehow calibrated to have the same response and action.
