Mr. Jensen 25.02.2026
Got mine in about a week ago and ran it through extensive testing.

Build quality is so-so, slightly misaligned inputs with respect to the chassis, thin, resonant plate steel and delicate wooden sides with sharp edges that will get dented easily.

My unit doesn't have the whine the initial units seemed to be suffering from, but it does have the issue of not bypassing the sound to the right channel (only left). Also, there's no way to completely turn down the volume, as sound always keeps bleeding through, even with Output set to 0.

The filters with respect to the patterns in the editor are mixed up, with the highest filter control actually affecting the lowest band. Very confusing and this makes the patterns play unlike they're intended to sound.

Same with MIDI notes to trigger the filters: The highest C controls the lowest band. Totally illogical and unlike the real MIDI Murf.

The unit is generally very unstable as soon as you want to start using it over MIDI from a DAW. The unit froze up on multiple occasions, like it could no longer handle any further MIDI input. Total freeze until power cycle.

When it is working, it's a really cool effect so I'm a bit torn. But I will have to return this one since I don't trust the damn thing. Will try again later.
