Analog FOUR filter freq values for deep bass

Howdy

A couple of points come to mind, whilst i am not sure what your end usage case will be in practice, i wonder if you realise a few things that may help

Firstly, the filter frequency is 14bit resolution, so for every ‘step’ you have noted above there is an extra resolution of 127 steps - so quoting ‘rounded’ freq values is not allowing much precision

Secondly, the filters can be KeyTracked so setting one value will mean teh filter freq follows (not so great on the ladder, but if used it could be serviceable for your needs over a short range) and for the peak (filter 2) the tracking is decent- set Tracking to 100% i.e. 32

Then tune the filter freq against the osc pitch however you like and keep in mind that (assiming iirc you have NRPN enabled) the resolution will be there between integer steps - the HighPass is useful in this role too
