Yes! They are basically 5u modules in pedal format. Never tried the big delays and chorus, but the minis are nice.
The MF-103 Phaser is the best phaser ever, and way more versatile than I ever thought a phaser could be. It can also be cranked into resonating for some awesome drum sounds.
The MF-102 Ring Mod is likewise very versatile. You can use it as a standalone triangle oscillator (or two in unison if you feed the osc into the input and dial in the Mix for sounds an octave up), or as a vca, or two lfos (the oscillator can do both subsonic oscillation and audio rate).
The MF-107 freqbox is a dedicated oscillator in a box with better pitch cv tracking, audio envelope tracking, variable waveforms, and analog FM.
The 101 is classic Moog ladder filter with lots of modular tweakability and an envelope follower.
Haven’t tried any of the others but they all seem great.
