I really like the strange sounds you get from the free version of the Oxidlab filter, so I went ahead and sprung for the paid stereo versions.
They do make a plethora of strange sounds, but as you switch between filter slopes, the stereo field jumps around jarringly. Primarily moving to the right as you select steeper slopes. I’ve written the developer about this, but no reply as of yet. I’m not sure if they are still actively involved in developing these devices.
Have others noticed this behavior?
