The MURF is its own thing. It has 8 filters and a mod sequencer. The MxB only has 2 filters and a mod sequencer. However, you can get some MURF-y effects with careful sequencing. You would need to use the custom stepped LFOs modulating cutoff and maybe res. What you won’t be able to replicate is having the filters in a stereo field. If you have external VCAs or a panner you could approximate that by using the same CV used on the mod sequence to control the panning.
